When recombined concrete, which is produced by mixing the hybrid concrete with a water-soluble polymer or latex which is an organic material and an acrylic polymer, is discharged to a shooting guide member, high pressure compression air of 5 or more atmosphere pressure is emitted, so that air included in the recombined concrete is evaporated and the hybrid concrete is made to have an air content of 3-7% and a slump of about 100-200 mm. The mixed quantity of latex which is generally mixed is reduced so that production costs can be greatly reduced. Also, when the recombined concrete is discharged, high-pressure compressed air of 5 or more atmospheres of pressure is emitted, so that air included in the recombined concrete is evaporated and the hybrid concrete is made to have an air content of 3-7% and a slump of about 100-200 mm. Accordingly, high strength and high durability can be ensured.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid concrete method for preparing a hybrid concrete,

The present invention relates to a hybrid concrete production method, and more particularly, to a method of manufacturing a hybrid concrete, which comprises mixing a plain concrete containing cement, water, and aggregate with a high-purity powdery pozzolanic material bubble slurry to form a mixed concrete, Or a water-soluble polymer and an acryl-based polymer is discharged into a shorting guide member, the air contained in the remodeling concrete is blown by compressed air having a pressure higher than 5 atm, so that the air content is 3 to 7% The present invention relates to a method for manufacturing a hybrid concrete by adding a high-pore zeolite slurry and a latex latex to produce a hybrid concrete which maintains a slump of 100 to 200 mm.

Lightweight foamed concrete is used for insulation in floor, wall, roof, etc. in the form of block, panel, filler and so on by reducing the density of concrete by introducing 20% or more stable pores into hardened paste or mortar. When the cement paste is used only for the lightweight foamed concrete, the density is about 0.3 to 0.5 t / m.sup.3, and when the mortar mixed with fine aggregate is used, the density is preferably about 0.8 to 1.5 t / m.sup.3.

The lightweight foamed concrete is classified into pre-foaming cellular concrete and post-foaming cellular concrete according to the generation time of the bubbles. The preliminary foaming method is used to increase the lightness by reducing the density by making voids in the inside by injecting the bubbles in the process of manufacturing the bubbles in advance, or by increasing the slump by using the ball bearing effect of the bubbles to improve the filling property .

Lightweight foam concrete can be used for cement paste (cement + water), mortar (cement + water + fine aggregate), concrete (cement + water + fine aggregate + coarse aggregate) It is usually used for cement paste or mortar, and it is very rare for concrete used with coarse aggregate. That is to say, the preliminary foam lightweight foamed concrete is prepared by mixing the preformed foam with cement paste or mortar to improve its lightness and filling properties.

For example, lightweight foamed mortar is prepared by previously foaming bubbles and mixing them with the mortar. At this time, the bubbles having a diameter of about 0.1 to 1.0 mm are uniformly dispersed in the mortar to increase the slump while reducing the density, It can be laid on the floor of apartment flooring and non-structural walls that require insulation, soundproofing, filling, etc., or it can be made of lightweight block or lightweight panel.

Lightweight foamed soils are prepared by blending prefoamed bubbles into cement paste and then blending them into the selected soil to form floc foll concrete. It is a lightweight bubble material that has greatly reduced.

The lightweight foam concrete is used for non-structural materials for light weight and filling properties, but is rarely used as a structural material. This is because when the air content is increased by 1%, the compressive strength of about 4% is lowered.

In addition, the high-strength pozzolanic material-containing concrete is a concrete made by mixing pozzolanic materials (silica fume, meta kaolin, fly ash, slag fine powder) with Portland cement concrete and has durability, long term strength, chemical resistance, water tightness, And so on. The pozzolanic material itself does not have hydraulic properties, but at room temperature, water and calcium hydroxide combine to form an insoluble salt, which is called a pozzolanic reaction, which improves the watertightness and strength of the cement.

Particularly, silica fume is a by-product of the ultra-fine particles produced when silicon (Si), ferro silicon (FeSi), silicone products and the like are produced. When mixed with concrete, Thereby improving the strength, decreasing the permeability and improving the durability.

In order to improve the performance of the concrete, a high-purity powdery material such as silica fume, metakaolin, fly ash and slag powder is used. Among them, silica fume and meta kaolin have high performance It is a typical material of concrete. The silica fume is 1 / 80-1 / 100 of the cement powder, filling the inside of the concrete. The inside of the concrete is filled up by the pozzolanic reaction to make the inside more tight and high durability and high durability. Due to its large specific surface area and poor workability, I use it with me.

The silica fume is generally used in an amount of 7 to 10% based on the weight of the cement. The silica fume is pre-blended in the cement to be used as a mixed cement. This is because, since silica fume is a fine powder, This is because the silica fume is not dispersed evenly when mixed with other concrete materials or mixed into concrete (ready-mixed concrete) already blended, which causes many problems.

When high-purity pozzolanic materials such as silica fume, meta kaolin, fly ash and slag fine powder are used, mixed cement is used for dispersion. When the mixed cement is used in a large quantity, it is produced and transported in the factory to the bulk, and the bulk transported on the site is prepared and used separately. When the used amount is medium or small, There is a problem in that the production cost is increased by separate transportation from the process.

The latex modified concrete is a concrete made by mixing latex with a certain amount of concrete. When the composition is mixed, the fluidity is greatly increased to improve the workability. After curing, the latex solid content fills the micro voids in the concrete, At the same time, a film film is formed to improve the durability of concrete such as decrease of permeability of concrete, increase of adhesion with new and old concrete, increase of degradation to crack, increase of freeze-thaw resistance.

The latex includes natural products and artificial chemicals obtained from rubber trees. The chemical latex is a polymer obtained by copolymerizing a polymer composed mainly of styrene and butadiene, , And adding a small amount of surfactant and stabilizer is a milky translucent liquid and small spherical (eg, 0.05 to 0.2μ) organic polymer particles such as colloids are dispersed in a stable state in water. The latex has a solid content of about 45 to 48%, and a small amount of an antifoer is added to stabilize the latex during copolymerization. In order to suppress the generation of bubbles during the latex modified concrete formulation, a defoamer And then added.

Table 1 is a specification chart of latex modified concrete generally used. As shown in Table 1, the latex produces 1 m3 of concrete, and 128 kg is mixed therein.

However, as the petroleum price surges, the latex value of chemical product surges to 1,800 / kg, and produces 1 m3 of concrete. Since latex value is only 230,400 won / m3, the production cost is greatly increased and economical efficiency is lowered.

In addition, latex modified concrete is produced and supplied using mobile mixer by supplying materials in the field due to its blending characteristics. It operates the mobile mixer equipment, supplies and transports materials and supplies equipment, There was a problem of falling.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a flow chart of the present invention.

The present invention relates to a method for producing a hybrid concrete by post-addition mixing of a high-

Water, cement, and aggregate at a predetermined ratio to produce ordinary concrete having a slump of 40 to 120 mm;

Mixing a high-purity powdered pozzolanic material with water to produce slurry and bubbles to produce a high-purity powdered pozzolana bubble slurry;

And discharging the hybrid concrete in which the slump is reduced by blowing air bubbles contained in the remodeling concrete when the remodulation concrete is discharged to the shorting guide member.

The hybrid concrete manufacturing process of the present invention will be described below.

As shown in FIG. 2, water, cement, aggregate, and the like supplied from the plant plant BP are mixed and mixed at a predetermined ratio to form a normal concrete having a slump of 40 to 120 mm, To the construction site.

As shown in FIG. 3, 1.5 kg of a high purity zeolite material (S) of silica fume, metakaolin, fly ash and slag fine powder except for latex, The slurry was mixed in a ratio of 1: 1, that is, in a ratio of 1: 1, and mixed with a screw mixer 20 to produce slurry. As shown in FIG. 4, 10 kg of bubbles (A) Is mixed with the vertical stirring mixer 30 to produce a bubble slurry. It is preferable that the mixing amount of the slurry and the bubble is mixed in consideration of the strength and slump of the hybrid concrete.

At this time, the bubble slurry is mixed with a vertical stirring mixer without using a horizontal rotary mixer. This is because the bubble (A) of the bubble slurry is so light that it can not be mixed with the horizontal rotary mixing device, This is because it can overcome the phenomenon of separation of materials coming from.

Among the methods of forming the bubbles, a foaming agent can be used. Generally, the bubbles are generated in the course of adding and stirring to the concrete and re-mixing. The bubbles are formed by high-speed rotation of the mixer. But it is crushed in the stirring process and the distribution is relatively uniform, but there is a large difference in the amount of bubbles generated according to the mixing time. As the foaming agent, there is aluminum powder, and 0.1 to 0.5% of the total amount of the hybrid concrete is preferably used.

5 shows an enlarged view of a mixture of the bubbles and the high-purity powder pozzolanic material air bubble slurry, wherein the size of the air bubble A contained in the high-purity powder pozzolanic material air bubble slurry is about 0.1 to 1 mm, ) Are dispersed evenly among the high-purity powdery materials (S), which are silica fumes.

The silica fume and meta kaolin of the high-purity pozzolanic material are mixed in an amount of 1 to 20 parts by weight based on 100 parts by weight of the cement forming the ordinary concrete, and the fly ash and the slag fine powder are mixed with 100 parts by weight of the cement forming the ordinary concrete The high strength and the high durability are inferior. When it is more than the above range, the high strength and the high durability do not appear to be higher. This is because the cost of construction increases and the amount of latex added can be reduced in the future.

Here, the latex includes an SB latex and an acrylic polymer.

The mixing ratio of the high-porescent powder of the pozzolanic material and the ordinary concrete is usually in the range of 1 to 3 m 3 of the high-purity powder pozzolanic material bubble slurry 300 To 400 L, so that the amount of bubbles in the mixed concrete is 30 to 35%.

In the present invention, as shown in FIGS. 6 to 7, when the high pores of the powder pozzolana material is charged into the concrete truck 40 into which the ordinary concrete is charged, the mixed portion 60 ) By the rotation of the mixing member 62, which is radially connected at one or more stages to the shaft 61 in accordance with the rotation of the shaft 61, the ordinary concrete and the high-pores pozzolanic material air bubble slurry are mixed. The latex is introduced into the ready-mixed concrete truck 40 in which the mixed concrete is formed and the latex is uniformly dispersed by the rotation of the mixing member 62 by the rotation of the shaft 61 To form the remodulated concrete.

8, the ordinary concrete conveyed to the remicon truck 40 is supplied to the hopper 63 of the mixing unit 60 ', and the ordinary concrete supplied to the hopper 63 is supplied to the mixer 60' Powder pozzolanic material air bubble slurry is introduced into the ordinary concrete and mixed with ordinary concrete and high-purity pozzolanic material bubble slurries by the rotation of the stirring rotary member 64 The mixed concrete may be supplied to the mixer unit 65 and then the latex may be supplied to and mixed with the mixer unit 65 to form the remodeling concrete.

In the mixed concrete, the high-purity powdered pozzolanic material (S) except latex is dispersed and mixed evenly in the concrete due to the ball bearing effect of the bubble (A), and the mixed concrete .

The amount of the latex to be added to the mixed concrete is preferably 2 to 15 parts by weight based on 100 parts by weight of the cement that forms the concrete according to the amount of the high-purity powdered pozzolanic material S, Therefore, it is preferable not to mix the high pores of the high pores with the air bubble slurry, but to add the high pores of the high pores of the pozzolanic material.

Here, the water-soluble polymer and the acrylic polymer may be mixed with 2 to 12 parts by weight based on 100 parts by weight of the cement forming the ordinary concrete, and the same effects as those in the case of mixing the latex are obtained. Because the cost is low and the construction cost can be reduced.

Table 2 shows the slump change of the remodeling concrete according to the mixing amount of silica fume and latex of the high-pores pozzolanic material.

                                                          (Unit: cm) Latex
Amount of mixing Concrete condition Silica fume content 6% 7% 8%
3% Usually concrete (OPC) 11 8 12 After mixing the air bubble slurry 22 21 24 After addition of latex 27 26.5 26 After the shorting 5 One 2

7% Usually concrete (OPC) 12 9.5 8 After mixing the air bubble slurry 21 19 22 After addition of latex 27 26 27 After the shorting 22 18 16

As shown in Table 2, when the latex was mixed at 3%, 5%, and 7%, the slump increased and the silica fume increased to 6% and 7% due to the surface active agent as the latex content increased. %, And 8%, it can be seen that the slump decreases after the shorting depending on the amount of silica fume mixed. It can be seen that when the mixing amount of silica fume is large and the mixing amount of latex is small, the slump is very small. This is due to the high surface area of silica fume. As a result, it can be understood that the optimum combination of 5% of latex and 7% of silica fume is most suitable.

Table 3 shows changes in the air amount according to the mixing amount of silica fume and latex.

                                                                (unit: %) Latex
Amount of mixing Concrete condition Silica fume content 6% 7% 8%
3% Usually concrete (OPC) over 10 over 10 over 10 After mixing the air bubble slurry 38.54 40.06 38.95 After addition of latex 32.45 35.76 32.37 After the shorting 6.0 7.0 5.5
5% Usually concrete (OPC) over 10 over 10 over 10 After mixing the air bubble slurry 37.87 39.76 41.53 After addition of latex 33.07 33.03 29.14 After the shorting 6.0 7.0 5.5
7% Usually concrete (OPC) over 10 over 10 over 10 After mixing the air bubble slurry 44.93 40.66 38.94 After addition of latex 31.76 28.1 26.12 After the shorting 5.0 5.2 5.5

As shown in Table 3, the amount of air was greatly increased due to the incorporation of the high-pores pozzolanic material bubble slurry, and the amount of air was decreased by the addition of latex. As the amount of latex was increased, the amount of decrease was increased. , And it can be understood that the combination of 5% of latex and 7% of silica fume is most suitable for the optimum formulation.

As described above, it can be seen that the bubble is removed by the antifoaming agent contained in the latex, and the slump is further increased due to the role of the surface active agent of the latex in the remodeling concrete in which the latex is further added. As shown in FIG. 11, it can be seen that the slump of the ordinary concrete is 120 mm. The slump of the mixed concrete containing the high-pores pozzolanic material bubble slurry is 240 mm, and the slump of the remodulated concrete mixed with the latex is 270 mm .

In other words, when the amount of air is increased by 1% in ordinary concrete, the compressive strength is reduced by about 4% in relation to the amount of air and compressive strength contained in ordinary concrete, so that the remodulated concrete containing a large amount of air bubbles is greatly reduced in strength It is difficult to use it as a structural material, and the slump increases, resulting in a deviation from the required workability range due to the placement of the remodeling concrete.

Therefore, shorting is performed through the shorting guide member 70 to reduce a large amount of air contained in the remodeling concrete.

The shorting guide member 70 is supplied to the inlet of a shorting guide body 71 detachably mounted on the feed truck 51 of the ready-mixed truck 40 and the pump car 50. The shorting guide body 70 includes a shorting guide body 71, Since the diameter of the center portion is smaller than that of both ends of the inlet and outlet through which the inside is penetrated, the redistilled concrete supplied to the shorting guide body 71 is compressed and pressure is generated.

12 to 14, the redistilled concrete passes through the center of the shorting guide member 71 to the outlet of the shorting guide member 71, which is larger than the diameter of the center portion, and at the same time, Pressure compressed air is supplied to the air supply hole 72 formed radially to the outer circumferential surface of the shorting guide member 71 and is vortexed and shorted to the outlet of the shorting guide member 71. The compressed air and the re- When the compressed air and the remodeling concrete are unfolded by the spray method as well as the unfolding method, the compressed air and the remodeling concrete collide, and a large amount of bubbles contained in the remodeling concrete are dispersed.

The amount of air bubbles contained in the redistilled concrete in which the bubbles are dissipated is reduced to 3 to 7% of the amount of air contained in the redistilled concrete so that the amount of air bubbles contained in the redistribution concrete is close to the amount of air contained in the ordinary concrete before mixing the high- Hybrid concrete that maintains a slump of 100 to 220 mm can be obtained.

The hybrid concrete is usually used for pavement pavement and requires the physical properties shown in Table 4, and it is possible to satisfy the slump and air mass standards in a hardened range because the silica fume and the latex are mixed and the strength and durability are very good.

Table 5 shows the 28 days compressive strength and flexural strength according to the amount of latex and silica fume admixture. The 28 day compressive strength is largely influenced by the amount of silica fume admixture, but it is hardly influenced by the amount of latex admixture. In terms of compressive strength, the optimum mixing ratio is 3% of latex, 7% of silica fume, 5% of latex, 7% of silica fume, and 5% of latex. In order to satisfy the compressive strength requirement of 27MPa, 3% - silica fume 8%.

The compressive strength at 28 days is hardly affected by the amount of silica fume, but is greatly influenced by the amount of latex incorporated. It can be seen that the flexural strength increases with the increase of the latex content, and the flexural strength required for cross- All are satisfied. As a result, it was found that 5% of latex and 7% of silica fume were most suitable for the optimum combination of compressive strength and flexural strength at 28 days after hardening of concrete and change of slump and after hardening.
