( Technical field )

This invention is a method for producing a hydraulic inorganic composite, in which a hydraulic inorganic curing material is pressed into the pores of a fibrous, granular, flaky, lumpy, or other porous substance, and an apparatus for producing the same. In particular, regarding the above-mentioned hydraulic inorganic curing material containing a porous substance under reduced pressure, subsequently, restoring the pressure to substantially normal pressure, continuously kneading, and then removing and curing. The present invention relates to a method and an apparatus for manufacturing a hydraulic inorganic composite.

Here, the term "hydraulic inorganic composite" refers to cement-based, slag-based, and silica-ash-based hydraulic inorganic-based curing raw materials.

(Background technology)

In many cases, the conventionally used concrete or motor is simply a mixture of cement, water and aggregate, and then cured. In this case, the cement and When the aggregate is porous, the air in the pores hinders the adhesion, and the strength of the aggregate itself cannot be utilized well, which is a drawback. ■ 0

, 舰ノ A technique is known in which the raw materials are kneaded in a mixer, depressurized, decompressed, and then taken out and cured (Japanese Patent Laid-Open No. 5 2 — 2 8 1 3 7; The above technique increases the water cement ratio to improve kneading, removes excess water and air by reducing the pressure, and restores pressure. Although it is attempted to crimp the cement paste onto the aggregate to obtain a good concrete, the experimental results show that the strength increase, etc. The effect of reforming is not seen. In addition, a method of depressurizing the porous aggregate in a mixer, adding a cement paste, kneading, and then re-pressurizing to remove and harden it (Kohokuni, JP 5-5-3). No. 0 9 6 2, Japanese Patent Laid-Open No. 5 5-3 0 9 8 3), a method in which a porous aggregate is used for decompressing, then taken out and hardened ('Shonhon Kokusho 5 5- 1 0 5 5 1 4) is also known. These are intended to increase the bond strength between the cement and the aggregate by press-fitting the cement mirco into the structure of the porous aggregate. Although the results show some increase in strength as will be described later, there was a drawback in that the bleeding was large and it was difficult to finish the surface of the concrete.

(Best Mode for Carrying Out the Invention)

The present invention will be described in detail below by using a blast furnace slag as the porous material and using cement and water as the hydraulic inorganic hardening material, with reference to the accompanying drawings. In addition, this specification In the claims and claims, the hydraulic inorganic composite is simply referred to as a composite for convenience.

Figures 1 and 2 show one example of a composite manufacturing device, where 1 is a mainframe and the mainframe 1 is connected by a cylinder 2. A mixer frame 3 is rotatably provided. The mixer shaft 5 protruding from the mixing drum 4 is supported by a bearing (not shown) of the mixer frame 3 and fixed to the mixing drum 4. The gear 6 and the prime mover attached to the mixer frame 3? The pinion 8 mounted on the rotary shaft (not shown) of the motor is engaged, and the mixing drum 4 is rotated by the rotation of the prime mover 7.

On the other hand, the base arm 9 is fixed to one side of the mixer frame 3, and the end arm 1 is attached to the tip of the base arm 9 by the cylinder 10. 1 is rotatably pivoted, and is attached to the end of the end arm 1 1 through a swivel 12 force swivel bracket 13. As shown in Fig. 3, the sino-belt 1 2 has a baling 15 fitted inside the s- ive-lens 14 as shown in Fig. 3. The hollow shaft 16 is rotatably mounted through the hollow shaft 16 and the hollow shaft 16 is closed on one side by the plug 17 and the other shaft L is integrated with the hollow shaft 16. It penetrates through the closed lid 18 and communicates with the inside of the mixing drum 4. A hole is provided in the middle of the hollow shaft 16 so that it communicates with the suction port 19 provided on the svelcase 14 and between the svenor case 14 and the hollow shaft 16. There is one Rule 20 is provided. The lid 1 8 is attached to the cylinder 1 0. It is detachably attached to the opening of the mixing drum 4 via the locking 21 and the bearing cover 2 2 and the retaining ring 23 are bearings. In addition to fixing 1 5, it also prevents the dropouts of the super case 1 4 and hollow shaft 1 6.

Next, a method for manufacturing a concrete (composite) using the above-described composite manufacturing apparatus A will be described. First, from the state shown in the figure, operate the cylinder 10 to open the lid 18 and open the required amount of blast furnace slag (multi-pore material) from the opening in the mixing drum 4. And cement and water (hardening raw material), operate the cylinder 10 again, close the opening of the mixing drum 4 with the lid 18 and operate the prime mover 7. Sasase mixing drum

Rotate 4 and knead. Next, while kneading, activate a vacuum suction device (not shown) to communicate with this.

Vacuum suction bow I inside the mixing drum 4 via 19 and re-pressurize the air in the pores of the blast furnace slag where it has been sufficiently degassed. Stop operation and start mixing drum

Stop rotation of 4 and operate cylinder 10 to open lid 18 and operate cylinder 2 to tilt mixing drum 4 and open the opening. Facing downwards, the raw concrete in the mixing drum (curing raw material containing the porous substance) is exposed to the outside, and this is driven into the mold to form and cure. As a result, a high-strength concrete (composite) in which a concrete component is injected into the pores of the blast furnace slag is obtained.

The above example is a composite using a rotating drum mixer.

OMPI

U. . ^ The following is an example of the manufacturing equipment A and a method of manufacturing a composite using this equipment.The other concrete mixers are made of raw concrete using blast furnace slag as aggregate. Into the mixing drum 4 of the manufacturing equipment A, rotate the mixing drum 4 and vacuum-suck while kneading, repressurize, and then continue kneading. It is not so good that it can be taken out and cured. In addition, the recompression pressure may be during the rotation of the mixing drum, at the same time as the rotation is stopped, or after the rotation is stopped. It is preferable to degas the blast furnace slag evenly by vacuum suction.

Above, we have described an example in which blast furnace slag was used as the porous material and cement and water were used as the curing raw materials.However, various materials were used for the porous material and the curing raw material, as described below. In addition, the curing raw material is not only one agent but also multiple agents in many cases. Therefore, the blast furnace slag and the like are simply porous materials, the cement and water are curing materials, and the materials that constitute the curing material, such as cement. Other examples will be described with reference to water and the like, a curing raw material containing a porous substance is a composite raw material, and the cured material is abbreviated as a composite.

Figures 4 to 11 show eight examples of composite manufacturing equipment consisting of an upper container 25 and a lower container 26 via a gate 24 that can be opened and closed. The decompression pipe is provided in communication with the upper container 25, the decompression pipe 28 is provided in communication with the lower container 26, and both decompression pipes 2 7 and 2 8 are shown. Not connected to a vacuum suction device. 2 9 is lower Diffusion plate provided at the bottom of the gate 2 4 of the vessel 26, 30 is an agitator provided in the upper container 25, 31 is an agitator provided in the lower container 26, 3 2 is A motor for driving and rotating the stirrers 3 0 and 3 1, 3 3 is a composite raw material, 3 4 is an introduction hole provided in the upper container 25, 3 5 is an outlet of the lower container 26, and O ₀

A method of manufacturing a composite using the composite manufacturing apparatus B shown in FIGS. 4 to 6 will be described. As shown in Fig. 4, the gate 2 4 and the outlet 35 are closed, the vacuum suction device is activated, and the lower container 26 is evacuated through the pressure reducing tube 28. Reduce the pressure by pressing, open the lid of the upper container 25, put the composite raw material 33 in the upper container 25 to fill it, and close the lid tightly. Next, as shown in Fig. 5, when the gate 24 is opened, the composite raw material 33 drops into the lower container 26 due to the pressure difference and its own weight. When the lower container 26 is decompressed after continuing vacuum suction for a while, the curing raw material contained in the composite raw material 3 3 is pressed into the pores of the degassed porous substance existing in the curing raw material. .. The discharge port 35 is opened here, the composite raw material 33 is taken out, and after kneading this with an appropriate mixer, it is placed in a mold and cured to obtain a composite. In this manufacturing method, the composite raw material is kneaded under reduced pressure to degas the porous material evenly, and the composite raw material 3 3 in the upper container 2 5 is depressurized in the lower container. While the porous material is allowed to fall into the inside of the chamber 26, the porous substance is degassed evenly, and the volume of the lower container 26 is larger than that of the upper container 25, and the volume of the lower container 26 is smaller. The height of container 2 6 is large

Ο ΡΙ The more effective it is. In this example, as shown in FIG. 6, the composite raw material 33 was not filled in the upper container 25, but was left in a space and dropped into the lower container 26. Good too. At this time, the pressure difference between the upper container 25 and the lower container 26 becomes large, and the composite raw material 3 3 falls vigorously into the lower container 2 6 and the composite raw material 3 3 easily disperses when falling. It is easy to uniformly degas porous materials, but since the degree of vacuum is low, it is necessary to make the lower container 26 larger than the upper container or to lower it.

It is desirable that the vacuum degree of 26 be higher than that of the upper container.

Producing apparatus B of the complex is shown in Figure 4 ~ Figure 6 is Ni would Yo manufacturing apparatus B _t of the complex shown in FIG. 7, the lid of the upper container 2 5 and fixed, taken An introduction hole 34 and a pressure reducing pipe 27 for putting the composite raw material may be provided in. When this device B is used, the composite raw material 3 3 is put into the upper container 25 from the introduction hole 3 4 to shut off and seal it, and the upper container 25 and the lower container are connected via the pressure reducing pipes 27 and 28. After vacuuming the inside of container 26 to reduce the pressure, open gate 24 and drop composite raw material 33 into lower container 26. At this time, if the vacuum degree in the lower container 26 is set higher than that in the upper container 25, the composite raw material 33 drops due to the pressure difference and its own weight, and when the vacuum degree is the same. Is a composite raw material

3 3 falls due to its own weight. Next, the composite raw material 33-is recompressed and taken out, kneaded with an appropriate mixer and then cured to form a composite, which is the same as explained in Figs. 4 to 6. It Fig. 8 shows the umbrella-shaped diffuser plate 29 without a handle, which is located below the gate 2 4 in the lower container 26 of the composite manufacturing apparatus B described in Figs. 4 to 6. A composite manufacturing apparatus B ₂ is shown, and a composite is manufactured in the same manner as described above, but when the gate 2 4 is opened and the composite raw material in the upper container 25 is dropped, the composite raw material is a diffusion plate 2 It is easy for the porous material to be degassed while being dispersed by the 9 while falling into the lower container 26.When the composite material falls When the diffuser plate 29 is rotated by an appropriate means Dispersion fall of is more effective. It should be noted that a diffuser such as a grating may be used instead of the diffuser plate 29.

Figure 9 is shows a manufacturing device B ₂ of the complex in which a stirring odor 3 1 to the lower container 2 in 6 of the manufacturing apparatus B complexes described in Figure 4-Figure 6, the mixing tool 3 1 Since it is provided, the bottom of the lower container 26 is formed horizontally. The manufacturing method of the composite is the same as the manufacturing equipment of the composite shown in Figs. 4 to 6 and Fig. 8, and the gate 2 4 and the outlet 35 are closed, and the inside of the lower container 26 is reduced. Pressurize and put the composite material in the upper container 25 and seal it-then open the gate 2 4 and let the composite material in the upper container 25 fall into the lower container 26, but further In order to perform even deaeration, the composite raw material that dropped into the lower container 26 was stirred with a stirrer 31 to restore the pressure, and then kneaded, and then the discharge port 35 was opened and the composite raw material was opened. It goes out and cures this. The recompression pressure may be during stirring, at the same time as stopping stirring, or at any time after stopping stirring. This device When using, close the outlet 35 and the gate 24, put the composite raw materials or materials (for example, cement water, blast furnace slag, etc.) in the upper container 25, and Open to drop the composite raw material or material into the lower container 26, close the gate 2 4 to seal the lower container 26, operate the motor 3 2 and rotate the stirrer 31. The composite raw material or the material is stirred and kneaded, and the inside of the lower container 26 is depressurized through the pressure reducing pipe 28, the pressure is restored, and the kneading is continued. It may be taken out and cured. In other words, the upper container was used as a meter or hopper.

FIG. 10 shows a composite structure in which an openable / closable gate 2 4 is provided between an upper container 25 equipped with a stirrer 30 and a pressure reducing pipe 27, and a lower container 2 6 equipped with a pressure reducing pipe 28. Body manufacturing device B ₄ is shown, and when using this device to assemble the composite, the composite raw material is put into the upper container 2 5 through the introduction hole (not shown), and the upper container 2 5'is hermetically sealed and the pressure reducing pipe 2 7 via the upper container

While depressurizing the inside of 25, the stirring tool is operated by operating the motor 32.

Stir the composite material at 30 and re-pressurize it, and then continue kneading, then open gate 24 to drop the composite material into the lower container, open discharge port 35 and take out the composite material to the outside. And cure. The upper container 25 and the lower container 2S were decompressed and the composite raw material in the upper container 25 was stirred, then the gate 24 was opened and dropped into the lower container 26, and the pressure was restored here. Take out the composite raw material, knead it again with an appropriate mixer, and cure it. Even if the upper container 25 is depressurized, the composite raw materials are stirred in this, and after the pressure is restored, the gate 24 is opened and the composite raw material is placed in the lower container 26 under reduced pressure. Alternatively, the lower container 25 may be dropped, the composite raw material may be taken out by recompressing the lower container 25, kneaded with an appropriate mixer, and then cured. It is also possible to put the material in the upper container 25 instead of the composite raw material, stir and knead it with the stirrer 30 to obtain the composite raw material, and perform the above steps to take out the composite raw material and cure it. The upper container may or may not be closed when kneading the ingredients. Ie upper container

If a stirrer 30 is installed in 25, it is possible to put materials such as cement, water, and blast furnace slag into the upper container 25 and stir and knead to combine the composite raw materials. If it is possible to hermetically decompress the inside of 2 5 and stir the mixed raw material, then re-pressurize it and drop it into the lower container 26, the stirrer 30 is used only for the production of the mixed raw material. It is also possible to decompress the lower container 26 and then drop the composite raw material into it to restore the pressure. At this time, the introduction hole may be blocked or opened 0

And then seal it, and reciprocally move the pressing tool 39. Valley I? The material inside was kneaded by kneading through 3 6 and the material 4 1 became a composite material, that is, after the material 4 1 was kneaded well, the inside of the container 3 6 was put through the decompression pipe 3 8. After depressurizing and degassing the porous material evenly, the pressure in the container 36 was restored, and the kneading and kneading were continued.After that, the reciprocating motion of the pressing tool 39 was stopped and the lid was opened to open the internal composite Then, the composite is taken out and cured to form a composite. As shown in Fig. 12 and Fig. 13, it is more effective for the horizontal pressing tool and the vertical pressing tool to perform the kneading effectively. It can be carried out.

Next, when the screw rod of the lower cylinder is retracted and the screw rod of the intermediate cylinder is moved forward, the composite raw material in the intermediate bag moves into the lower bag and the upper cylinder moves. When the piston rod of the binder is retracted, the composite material fills the upper bag. Next, when the piston rod of the lower cylinder is advanced, the composite raw material in the lower bag falls and becomes a hook. If the composite raw material in the upper bag is dropped by dropping the inner cylinder into the upper bag and retracting the intermediate cylinder's piston rod and advancing the upper cylinder's piston rod. Move to the middle bag. By repeating this operation, it is possible to intermittently discharge the composite raw material without hindering the depressurized state in the continuous mixer 65. The mixture is kneaded in one step and cured to obtain a composite, but a continuous mixer may be used as the mixer after recompression.

The operating order of the valves is not limited to the above order. Figures 26 to 30 show the operating sequence of the ejector cylinders consisting of the pressure plate 6 6a, one flexible tube 8 3'a and 3 cylinders. , 8 3 c is the cylinder's best rod. That is, three sets of valves are formed by the pressure receiving plate, the flexible pipe, and the three cylinders. One flexible tube was used in place of the three bags of the discharge device in Fig. 23, and since the discharge principle is the same, the cylinder of this discharge device is The operating sequence is used for the ejector of Figure 23 and the operating sequence of the cylinder of Figure 23 is used for the ejector.

Lower cushion rod as shown in Fig. 26 and then retract the upper cushion rod as shown in Fig. 26, and repeat this operation. Intermittently discharge the composite raw materials that have been mixed in the mixer 65.

The discharge device described above uses three sets of valves, but as shown in Figs. 31 to 34, the discharge device using two sets of valves is a continuous mixer. It is possible to discharge complex material without hindering the depressurized state inside the mixer 65. Since this ejector is merely the one with the middle cylinder of the ejector shown in Fig. 26 to Fig. 30 removed, the detailed structure is omitted.

At the same time, when closing the bottom nozzle 8 7 and opening the vacuum valve 8 8, the inside of the bottom container 8 6 is also at the same atmospheric pressure as the inside of the continuous mixer 6 5, so the top volume F 8 When 5 is filled with the composite material, opening the upper valve 8 7 moves the composite material in the upper container 8 5 into the lower container 8 6. Next, when the upper valve 8 7 is closed and the vacuum valve is closed and the lower valve 8 7 is opened, the composite raw material is discharged from the lower container 8 6 and the composite raw material is collected in the upper container 8 5. .. This operation is repeated to intermittently discharge the composite raw material.

A downward pipe 8 9 provided in communication with the discharge port of 6 5 has a level detector (not shown) or a weight measuring device (not shown) and an openable gate 90 at the lower end. It has been done. F is the force to push up the composite raw material in the downward pipe 8 9 and P is the atmospheric pressure. , If the atmospheric pressure in the continuous mixer -65 is P, and the cross-sectional area of the downward pipe is A, then the formula F = ( _P.Pt ) A holds, and the composite in the downward pipe 89 is Raw material height h, weight

If W and specific gravity are d, then the formula W = A h d holds.

If W> F, then the low pressure is maintained in the continuous mixer 65, so that the composite raw material always has a constant weight within the above range-this Λ ;, _r s If the gate 90 is opened so that the composite material can be maintained and the composite material is discharged intermittently in small amounts, it is possible to discharge the composite material without disturbing the depressurized state in the continuous mixer 65. You can In the figure, the vacuum tank 69, gauge 70 and vacuum suction device 68 are omitted.

The continuous production apparatus for composites has been described above, but the composite material discharged from the discharge device to the hopper 84 is kneaded again, taken out, and cured to obtain a composite.

Next, after the pressure inside the container 9 1 is restored and the mixture is agitated by the agitator 9.7, the supply pipe 9 2 and the decompression pipe 9 5 are closed, and the discharge pipe 9 4 and the pressurization pipe 9 6 are opened. When one is operated to pressurize the inside of the container 91, the composite raw material in the container 9 1 is discharged from the discharge pipe 9 4. Next, stop the operation of the compressor, close the pressure pipe 9 6 and the discharge pipe 9 4, and open the decompression pipe 9 5 to activate the vacuum suction device, so that the pressure inside the container 9 1 is reduced.

In addition, the container 103 is provided with a supply pipe 1104, a discharge pipe 105, a pressure reducing pipe 106, and a pressurizing pipe 107. That is, a cylinder 999 was added to the continuous production system for composites shown in Fig. 35, and the method for producing composites is the same as that explained in Fig. 35. Although the details are omitted, it is possible to depressurize and pressurize the inside of the container 10 3 by using the cylinder 99, so the depressurizing pipe 10 6 and the pressurizing pipe 10 7 must be used. However, it is not necessary. In addition, it is similar to the equipment granule in Fig. 35 that an agitator is installed in the container 103.

By repeating the above, it is possible to intermittently and continuously discharge the composite raw material. Like the hopper, it is desirable that the shape of the container is such that the lower part has a small diameter, and it is not necessary to use compressed air to discharge the mixed raw materials if such a shape is used.

Figure 37 shows a fluid pump Ε which can also be used in place of the other rotary feeders 74 that can be used in the discharge device. , 1 0 8 connects both ends of the semicircular type.

m A substantially semicircular casing with a cross-sectional shape extending in the line direction, 109 is a flexible tube arranged in a U shape along its inner surface, and 110 is a casing. It is an arm that rotates concentrically with the semi-circular portion of the casing 1 0 '8, and a lower arm of the same contour is provided below the arm 1 10 and the drive shaft 1 1 3 are inserted into the central bearing of the arm 1 10 and the central bearing of the lower arm, and the driven shafts 1 1 4 and 1 1 4'are the end bearings of the arm 1 1 0, respectively. It is fitted to the end bearing of the lower arm. In addition, the drive shaft 1 1 3 has drive shaft sprockets 1 15 attached to the upper and lower parts, respectively, and the upper drive shaft sprockets 1 1 5 and the driven shaft 1 1 5 A chain 1 1 6 is wound between a driven shaft sprocket 1 1 1 fixed to the upper part of 4 and a lower drive shaft sp σ 1 1 5 and driven shaft 114 lower part. A chain 1 1 6 ′ is wound between the driven shaft sprocket 1 1 1 ′ fixed to the drive shaft 113, and when the drive shaft 113 is rotated in the direction of the arrow by the power, the driven shaft 1 1 1 1 ′ is rotated. 4 and 1 1 4 ′ also rotate in the direction of the arrow, and the large diameter parts of the driven shafts 1 1 4 and 1 1 4 ′, that is, the rotary rollers 1 1 2 and 1 1 2 ′, respectively, are flexible tubes 1 0 9 While moving by pressing, the fluid body (fluid material, curing raw material, composite raw material, etc.) in the flexible tube 109 is pushed and conveyed in a certain direction. The arm 1 1 0 also rotates in the direction of the arrow around the drive shaft 1 1 3. An arm similar to arm 1 10 was installed orthogonally to arm 1 1 0, and four rotating rollers were made to rotate on their own axis to convey the fluid inside flexible tube 1 09. Good and good. That is, if one side of the flexible tube is connected to a continuous mixer or a storage tank, and the drive shaft 1 1 3 is rotated by operating a prime mover (not shown), the continuous mixer is It is possible to continuously discharge the fluid, which is connected to the sir or is stored in the storage tank, from the other side of the flexible tube, and the pressure can be restored at the same time as the discharge. Therefore, the continuous mixer 65 shown in Fig. 23 can be installed and used in place of the discharge device 66, and the material supplied to the continuous mixer 65 is a composite raw material. In the case of a liquid such as the above, it can be used in place of the mouthpiece feeder 1 74.

For the fluid pump, rotate the arm fixed to the drive shaft and press the flexible tube with the rotary rollers rotatably attached to both ends of the arm. A fluid pump that conveys fluid in a flexible tube while L is also known, and the fluid pump including the fluid pump E described above is collectively referred to as F. The following will describe another example of the manufacturing method of the composite body and the manufacturing apparatus.

In Figures 38 to 42, 1 1 7 is a storage tank for temporarily storing the composite raw material 1 3 0, which is connected by the continuous mixer 1 1 8 etc. shown in Figure 4 2, 1 1 9 is a supply pipe for supplying composite raw material from a storage tank 1 17 to a container 1 2 0 or a continuous mixer 1 2 1, and 1 2 2 is a container 1 2 0 or a continuous mixer. Vacuum suction device installed in 1 2 1 via decompression pipe 1 2 3, 1 2 4 is gas-liquid separator installed in decompression pipe 1 2 3, 1 2 5 is container 1 2 0 or continuous The discharge pipe for discharging the composite raw material from the mixer 1 2 1, F is installed in the supply pipe 1 1 9 and the discharge pipe 1 2 5.

O PI _ It is a pump for fluids, and flexible pipes on both sides of the pump are attached to the flood picture tube 1 19 and the discharge tube 1 2 5. In addition, 126 is a rotary diffuser plate provided in the container 120 shown in Fig. 39-1 2 7 is an agitator provided in the container 120 shown in 40-1 2 8 is a rotary type A diffuser 1 2 6, a stirrer 1 2 7 and a prime mover for driving the warped continuous mixers 1 1 8 and 1 2 1 respectively, and 1 2 9 is a supply pipe 13 inside the continuous mixer 1 1 8 in Fig. 42. The material supplied through 1 and 1 3 2 are discharge pipes for discharging the composite raw material 1 3 0 mixed and kneaded by the continuous mixer 1 1 8 to the storage tank 11 1 Ί.

In other words, all of the composite manufacturing devices shown in Figs. 38 to 42 store the composite raw material 130 made by kneading a plurality of materials with a continuous mixer 118 or the like. The fluid pump of the supply pipe 1 1 9 is temporarily stored in 1 1 7 and is stored in a container 1 2 0 or a continuous mixer 1 2 1 whose pressure is reduced by a vacuum suction device 1 2 2. While it is continuously supplied via F, it is discharged via the fluid pump F of the discharge pipe 1 2 5 and is recompressed and discharged to a hopper or the like not shown. The recompressed composite raw material is kneaded with an appropriate mixer, taken out, and cured to obtain a composite. For the purpose of evenly reducing the pressure of the composite raw material 130, in the device shown in Fig. 38, the height of the container 120 is increased so that the composite raw material is uniformly depressurized when dropped. Therefore, in the device shown in Fig. 39, the depressurizing effect due to the dispersion of the composite raw materials is taken into consideration by using the rotary diffuser plate 1 2 6 (either a fixed diffuser plate or a disperser may be used). .. In addition, under the reduced pressure The composite raw material of Fig. 41 and Fig. 42 is stirred by a stirrer and the uniform decompression of the composite raw material is considered by utilizing the expansion of continuous mixer .1 21 under reduced pressure. It is being touched. The mixer for supplying the composite raw material to the storage tank 1 17 by the above-mentioned manufacturing apparatus is not limited to the continuous mixer 1 18 shown in Fig. 42, but the storage tank 1 1 7 As long as the composite raw material is stored in the inside of the mixer, it may be a mixer that connects the composite raw material for each lot.

Figures 43 and 44 show two examples of production equipment for producing a foam-containing composite material by further entrapping the composite material 1300 produced as described above into a foam-containing composite material. Is the discharge pipe of the composite manufacturing equipment in Figs. 38 to 42, F is the fluid pump provided in the discharge pipe 1 2 5, 1 3 3 is a foaming machine, and 1 3 4 is A foam supply pipe for supplying the foam made by the foaming machine 1 3 3 into the mixer 1 3 5, and 1 3 6 is discharged from the discharge pipe 1 2 5 into the mixer 1 3 5. Mixing material and foaming machine 1 3 3 Kneading foam 1 3 7 to stir the foamed composite material, 1 3 8 is a prime mover driving the stirring tool 1 3 6, 1 3 9 Is a discharge pipe that discharges the foam composite material that has been packed in the mixer 1 3 5; 1 4 0 is a storage tank that temporarily stores the foam composite material 141 that is discharged from the discharge pipe 1 3 9; 4 2 is a discharge pipe for discharging the foam composite material 1 41 in the Lizhong Kwa 1 4 0, F is a fluid pump provided in the discharge pipe 1 4 2, and 1 4 3 is a continuous mixer. -The flow meter installed on the foam supply pipe 1 3 4 between the 144 and the foaming machine 1 3 3, 1 4 5 is the discharge pipe 1 2 5 from the discharge pipe 1 2 5 in the continuous mixer 1 4 4.

O PI Composite raw material supplied and foaming machine 1 3 3 A foam composite material that is kneaded and mixed with foam, 1 4 7 is a foam composite material that is connected by a continuous mixer 1 4 1 It is a discharge pipe that discharges 45 o

Although not shown, a mixer for kneading the composite raw material after decompression is provided in the middle of the discharge pipe 1 25.

In the device shown in Fig. 43, the mixer 1 3 3 mixes the composite raw material discharged from the discharge pipe 1 2 5 with the discharge pipe 1 3 9 closed and the foam created by the foaming machine 1 3 3. Mix the mixture in 5 to fill the foam composite raw material, open the discharge pipe 1 3 9 and discharge it to the storage tank 1 4 0.Continue from the discharge pipe 4 2 by operating the pump F for fluid. However, in this equipment, the composite foam raw material is connected to each wire, so the supply of the composite raw material to the mill Φ 1135 is shown in Figs. 38 to 42. Instead of supplying from the device in the figure, it may be supplied from the device as described in FIGS. 1 to 36.

The device shown in Fig. 44 continuously feeds the composite raw materials continuously supplied from the discharge pipe 1 2 5 and the foam continuously supplied from the foaming machine 1 3 3 to the continuous mixer 1 4 4. The mixture is kneaded to form a composite foam, and this is continuously discharged from the discharge pipe 1447. In addition, the discharge amount of the pump F for fluid and the flow rate of bubbles detected at h m.st 1 4 3 are controlled by a controller (not shown) to connect the sapphire composite raw material with an arbitrary mixing ratio. While (1) 4 6 is a motor, it is a prime mover driving a continuous mixer-1 4 4 <5>.

The manufacturing method of composite raw materials and foam-containing composite raw materials has been described above. However, it is advisable to automatically control the compounding of materials, the degree of pressure reduction, the discharge amount of pumps, etc. to obtain the desired composite material or further the foam-containing composite material, and to cure it. Not really.

Although many embodiments have been described above, any of the above embodiments may be configured as described below as appropriate.

(1) The material or composite raw material may be stirred under reduced pressure.

(2) The composite raw material under reduced pressure may be recompressed while being stirred.

(3) Porous materials include pearlite, glass foam granules, blast furnace slag, meteorites, man-made bean aggregate (mesalite, celite, etc.), porous slag, and carbon. , Silicon carbide, glass, alkalous glass, metal, silicon nitride, synthetic resin, etc. can be used, and 1 or 2 or more of the above porous materials can be used for composite materials. can do.

(4) Fibers, pieces, grains, lumps, and other shapes can be used as the porous material, and one or more of the above porous materials can be used as the composite raw material. can do.

(5) As a curing raw material, a hydraulic inorganic type (cement type, dregs type, and silica ash type) curing raw material can be used.

(6) Drying, heating, steam curing, autoclave curing, etc. can be used to cure the composite raw material.

Next, blast furnace slag was used as the porous material, cement and water were used as the hardening raw materials, and the hardening raw material containing the porous material under reduced pressure was decompressed and immediately taken out. A method for producing a cured composite (concrete) will be described as a reference example, and then an example will be shown in which kneading is continued after the above pressure recovery. Reference example 1

In the draft drum 4 shown in Fig. 1 to Fig. 3, 4 parts by weight of cement, 14 5 parts by weight of water, 6 17 parts by weight of sand 6 100 parts by weight of blast furnace-100 parts by weight of blast furnace slag Portion, close the lid 18 to seal the mixing drum 4, and rotate the mixing drum 4 to knead the above materials and perform sufficient kneading. The pressure in the mixing drum 4 was reduced to 600 Satsuma Hg at the place where there was no splattering of the ment, and kneading was continued for 4 minutes under this reduced pressure. The internal pressure of the interior of the mixing chamber 4 is restored to the atmosphere, the rotation of the mixing chamber 4 is stopped, the lid '18 is opened, and the mixing chamber 4 is tilted to produce the composite raw material. It was taken out, cast into a mold, molded, and cured by steam curing, and then released from the mold to obtain a composite steel (concrete).

In the above reference example, the composite raw material (uncured concrete) has a slump of 7.5 cra, the compressive strength of 7 scoops is 407.6 kg / cnf, and the compressive strength after scooping is 5 4 8 It was found that the strength was kg / cnf, which was slightly higher than that of what was cured without being depressurized. In addition to the above-mentioned reference example, various compounding ratios and particle diameters of the materials were tested, but in the case of a composition intended for high strength, the maximum compressive strength of 960 kg / cni could be obtained. -Generally, a compressive strength of 600 to 900 kg / erf can be obtained relatively easily, and bending strength and tensile strength also increase with this, and a uniform mouth with little variation is obtained.

We were able to obtain a lightweight, high-strength or high-strength concrete. In the case of lightweight and high strength concrete, cement material is pressed into the center of the blast furnace slag.

ΟΜΡΙ

H

: R ATV It is considered that unretained pores or cavities remained, and in the case of high-strength concrete, the grain size of the blast furnace slag was small and the cement material was pressed into all the pores. .. Moreover, as a result of examining the strains on the compression side and the tension side in the bending test, the proportional limit stress ratio deviates from the constant value of about 0.67 and a high stress ratio. Therefore, it was also considered that the initial cracks are less likely to occur than the conventional concrete. The good results as described above were obtained because the cement material pressed into the surface texture of the blast furnace slag became innumerable needles and stuck into the blast furnace slag. It is considered that the strength was high because the blast furnace slag itself was integrated with the ground and the blast furnace slag itself was reinforced by the press-in cement material.

As described above, a method for manufacturing a cement-based composite in which the composite raw material is taken out and cured immediately after recompression is described as a reference example ^, but as compared with the case where a non-porous material such as gravel is used. However, although it had high strength, it had a drawback that it had a large amount of bleeding and it was difficult to finish the surface. In the publicly known technology disclosed in Japanese Patent Laid-Open No. 5-390062, it is necessary to take out the composite raw material and cure it immediately after recompression. It is thought that this is because the air is removed to obtain a dense and strong composite, and the air that has been removed by the kneading is not mixed again. Then, after the pressure is restored and the mixture is kneaded again to be hardened, the pringing is remarkably removed, and in addition, a composite having higher strength is obtained. Based on this knowledge, we can obtain excellent effects that cannot be predicted at all, and open the way to practical use. I was able to do it.

Example 1

340 parts by weight of water, 165 parts by weight of water, 717 parts by weight of sand, and 1140 parts by weight of blast furnace sludge were produced using the manufacturing equipment described in Figs. 1 to 3. Knead, depressurize to 600 m ni H g and continue kneading for 4 minutes, then return to atmospheric pressure while kneading, knead for another 30 minutes, then remove and harden the composite (concrete). ))

The following table shows the slump value and the test value of the compressive strength of the composite obtained in Example 1, Reference Example 1 and the conventional conventional technique.

As can be seen from the above, the decompressed one has a higher strength than the non-decompressed one and the blast furnace slugger has a higher strength than the one using gravel. What is more, the blast furnace sludge was decompressed, decompressed, and kneaded for 30 minutes and then taken out. Only when the lamp was large, there was no bridging, and it was not possible to believe that the strength was even stronger.

The difference between the test Να 3 ,: 4 and the test Not 5, 6 and 7 is that the blast furnace slag used in the test NOL 3 and 4 has a large drainage rate. This is due to the low water content of the blast furnace slag used for tests Να 5, 6, and 7.

The reason why the strength of the kneaded product after kneading for 30 minutes after being decompressed and then re-compressed was higher, and the slump was greater was probably The pressure-time cement mill is rapidly injected into the furnace slag, which causes the residual air in the blast furnace slag to be compressed and become higher than normal pressure. It is considered that only the water in the lag is gradually released to the outside of the blast furnace oa; i> ~ There is a lot of bridging that was taken out immediately after the pressure was restored. Therefore, it is considered that the water released from the blast furnace slugged well and did not knead.

Example 2

Using the foaming machine 1 3 3 shown in Fig. 43 and Fig. 44, a foaming agent consisting of a stabilizer, a surfactant, and water are used to generate foam. That is, the composite raw material (uncured concrete) prepared in Example 1 was mixed with the above-mentioned foam in a volume ratio of 3: 1 to form the combined foamed composite raw material into a mold. It was cast into a frame and cured to obtain a lightweight high-strength composite (lightweight high-strength cellular concrete).

In the above example, blast furnace slag powder, such as crushed blast furnace slag, cement and water were used to set the blast furnace slag with a water content ratio of about 55% by the method of Example 1. A slurry (composite raw material) in which a hot substance has been pressed may be obtained, and then a foam may be mixed and cured to form an air bubble concrete (composite). When mixing foams to form a foam-containing composite material, if the water mixture of the foaming agent used for foaming and water is used as the water during the production of the composite material, It is easy to adjust the bulk specific gravity of. Moreover, if a water reducing agent such as a cellulosic type is used, a composite material having a low water cement ratio can be obtained to obtain a composite having high strength. 3 Although the manufacturing apparatus described in the figure is used, the present invention can be carried out by using other manufacturing apparatuses disclosed in this specification and the drawings and by using other porous materials. .. In these cases as well, the effect of the same tendency as that of the above-described embodiment was obtained, and therefore the details are omitted.

(1) It is possible to use water slag or slowly cooled slag as the porous material.
