Description

Polishing loess granule mortar composition and flooring construction method using dry dust grinding

The present invention relates to a loess granule mortar composition and a construction method capable of polishing a surface by applying a loess grain (hereinafter referred to as 'Granule') crushed to a particle size of 0.5 mm to 6 mm on the bottom surface, By combining ocherite granules and cemented carbide cements to meet the physical properties required by flooring materials, surface polished natural ocherite textures are applied to the floor of the building to reduce heating costs, deodorization and other useful effects of ocherite. It relates to a loess stone granule mortar composition and a construction method that can realize a comfortable living environment.

Loess rock refers to loess rocks in which deposited or stacked loess is solidified by pressure for hundreds of millions of years. In order to help the understanding of the present invention looks at the loess.

Ocher is a high-molecular sediment, which contains numerous minerals such as silica, alumina, iron, magnesium, sodium, and cary. If pure ocher's physical properties, ocher is coarse and more viscous than kaolin or clay, it has light yellow or pink color. It is a mineral that is very beneficial to the human body by emitting a large amount of microorganisms, far infrared rays and anions that are beneficial to the human body.

In particular, the loess of our country consists of yellow sand that has been flying for hundreds of thousands of years from mainland China, and its components include catalase, diphenol oxidase, saccharase, and protease. It is responsible for degrading power, fertilizer and purification.

In particular, catalase is known to show the highest activity among the elements of soil at present, and this enzyme removes hydrogen peroxide, which provides toxins to organisms, and plays a role in creating proper soil environment for living organisms. In the metabolism process, toxic lipid peroxide occurs during aging, and if it is put into high quality loess, it is known to have the effect of inhibiting aging by neutralizing and diluting lipid peroxide, which is a toxin in the body, with strong absorption power of soil. .

The specific action and efficacy of ocherite are as follows.

(1) Natural ocherite is known to bring out the above-mentioned heat, so that the head is cold and the feet are warm.

(2) 1 g of ocher contains 200 million microorganisms that are beneficial to the human body, and it is also referred to as a living and breathing ocher stone. A large amount of far-infrared rays emitted from ocher stone penetrate into human skin tissues to promote cell activation. It is useful for preventing aging, promoting blood circulation, relieving stress, skin care, neuralgia, back pain, and recovery from chronic fatigue.

(3) Natural loess is absorbed when the humidity is high and divergent when dried.

(4) Since natural ocherite has an anion release effect, modern buildings are actively using ocher and ocherite as building materials to block toxins and environmentally harmful substances in cement, and in some applications, the most suitable moisture for maintaining body temperature. Providing a pleasant living environment by maintaining (compatibility).

(5) Natural loess has a deodorizing ability to deodorize various odors such as toilet odor, food odor and tobacco odor, as well as circulating air due to fine pore distributed in loess.

(6) Natural ocherite can suppress the fungus and habitat of various fungi harmful to human body.

(7) Natural ocherite can act to neutralize lipid peroxide, which is bad for human body, and improve the constitution of human body.

(8) Natural ocherite has fine pores in the particles to provide excellent heat insulation and warmth, as well as a relatively warm and soft texture. In addition, ocherite has a higher heat storage rate and a lower heat conductivity, and thus has a higher heat preservation rate than cement floorboards. Thus, when ocherite is used as a flooring material in a room, heating and heating efficiency can be greatly improved and heating costs can be reduced.

Unlike ordinary stone, ocher stone can feel warm without being cool. Also, ocher stone is excellent in decorability because the sediment layer formed by sediment is similar to wood grain pattern.

(9) Ocherite is a very weak "+" electricity in the air has a variety of fine particles (ions) floating in it, ocherite is a "-" electricity, so a slight "+" electricity that causes static electricity and a slight "-" of ocher The electricity is neutralized to prevent static electricity.

As discussed above, the problems that were not developed despite the excellent characteristics of ocherite were developed mainly on ore, but ocherite is easily broken due to low hardness due to low hardness, so it can be used as a large size slab or plate (mat). Due to the difficult and expensive background, it is used as a building material.

Recently, due to environmental problems, a lot of attention to the residential environment, efforts to create a more useful residential environment for the human body is active, of which efforts to develop loess or loess as a building material is active.

The natural ocherite in the form of rock is cut like ordinary marble and wet ground at the factory and used as a polished plate. Scratches or surface hardness and strength is weak, there is a problem that is easily broken or scratched by the impact of external pressure during the construction process or the maintenance process used after the construction of the ocher stone plate. Thus, in the case of the ocher plate-shaped body cut to a certain thickness due to the remarkable physical properties, the physical properties of the ocher stone are limited to the conditions of building materials.

In the manufacture of various mortars in order to compensate for the weaknesses of the ocherite construction and to utilize the inherent useful functions of the ocherite in the residential environment, it is possible to use the flooring in a granular form more easily.

The present inventors have been interested in using ocherite in granule form, that is, utilizing crushed ocherite in granules having a certain size.

The present inventors have found that there is another problem as described above in order to compensate for the weakness of the physical properties of loess in using loess as a building material.

Granular ocher granules mortar is covered with cement on the surface of the bottom after curing. Grinding out the ocher granules inside shows the whole surface of the granules.

In general, marble can be obtained from the factory in the wet state by the surface grinding process to obtain a smooth surface, but in the case of ocher granule mortar mortar has low physical properties, that is, the compressive strength or adhesive strength is low As shown in [Picture 1], a problem arises in that the loam grains and the hardened cement are easily separated from the bottom surface. In Korea Patent Publication No. 10-632341 (notice date: October 11, 2006), the compressive strength of ocher mortar is 3, 7 days, 38.7 ~ 71, 80.7 ~ 132.7 kg / ㎠, 3.8 ~ 7.1 8.0 ~ 13.2 N / mm2 . Much less than 20 N / mm 2 concrete and weaker than cement mortar compressive strength. It is unimaginable to use dry clay gloss grinding with a compressive strength of 50 N / mm2 or more using this loess mortar technology. Grinding with a grinding machine, not to mention the impossibility of polishing, will cause the machine to fall out, making it impossible to move. Therefore, it is more advanced and new than existing loess mortar technology.

[Revision under Rule 91 05.10.2011]

On the other hand, cement and fixed loess granule particles acting as a binder filled between loamy granules and granules slide over the loess granules and cement granules, which are missing as the binder (cement) particles fall out as well as the loess granules during the initial polishing process. Due to the problem that the scratch is continuously generated on the surface being polished due to the rise, the polishing time is further increased and the surface is difficult to be polished. Even if the surface gloss can be made, as shown in [Picture 1] above, dozens to hundreds of small and large pores are generated in the 10cm width area, so it is necessary to continue to fill and cure the grinding and repeat this process continuously. Therefore, the air is long and the quality of the loess bottom surface is very poor, there is a problem that can not be successfully used as a universal material.

If the cement particles between the loess granules and the granules continue to come out, the polishing of the polished surface is not possible in dry grinding with a high pressure dust collector.

This problem becomes a fatal defect in processing the loess texture by uniformly distributing the loess granules throughout the bottom surface.

In order to solve this problem, the granule mortar should be ground by grinding to minimize the number of cement particles coming out during the primary grinding process. After initial grinding, the pores of the supersonic cements which have partially escaped between the ocher granules and the granules are filled with ocher powder and Low moisture-containing ocherite powder mortar mixed with superhard cement and water-repellent polycarboxylic acid is slush-coated to fill the pores, and after curing, dry-gloss polished to complete the final polished ocher granule flooring.

As shown in Figures 4 and 5, the loess is a sedimentary rock, so as shown in Figure 6, since the surface is open pores, that is, the pores are open, the cemented carbide cement particles and the loess powder are pushed into the open pores of the granules, thereby making a three-dimensional connection. Combining compressive strength is more than 50 N / ㎠. This is the key point of the present invention. The 28-day curing strength of ready-made superhard concrete is 375 kg / cm2, that is, 37.5 N / mm2, and the 10-day curing strength of ocherite granule mortar without sand and gravel is near 60 N / mm2. If the loess is not sedimentary rocks and ordinary rocks, the compressive strength is not so high.

Ocherite granules of 0.5 to 6 mm in diameter and ocher powders of less than 0.05 mm are mixed with cement without sand and gravel, resulting in creativity, novelty and advancement of more than 50 N / mm2. It is not possible to expect the present invention in view of any comparative invention.

Generally, gravel concrete is known to have the highest compressive strength, and when the cemented cement is used only in ocher, when the 28 days compressive strength of cemented carbide cement manufacturer is 37.5 N / mm2, the marble strength is more than 50 N / mm2. It is unimaginable to assume that this will come naturally. Therefore, creativity, novelty, and progressiveness will be excellent and it will be the most suitable for commercialization by using dry dust collection.

Existing environment has been completely withdrawn from the market despite many great advantages such as unified and flawless flooring using wet grinding as an environmental problem. Glossy loess granule mortar using dry dust is energy-saving, environmentally friendly, etc. If a product and a process with many advantages are patented, it will be a very effective countermeasure against global warming due to carbon dioxide and national policies represented by low carbon green growth, so it will be widely adopted and put into practical use in the world. It will form new industry trends.

In general, the polishing of marble is possible because the factory uses a good grinding tool in the wet state. In addition, the compressive strength of the marble is 55 ~ 120 N / ㎜ and the compressive strength is moderately high because it is relatively easy to polish. It is not only difficult to polish the surface if it is too high like granite, but there is no added value to do so. A compressive strength of 50-90 N / mm 2 would be most suitable for gloss grinding.

In dry grinding, if the compressive strength is 60 N / mm 2 or more, the strength is so high that it is difficult to be used industrially because of poor construction properties. Therefore, the compressive strength of 50 ~ 60 N / ㎡ is the most suitable compressive strength in grinding using dry dust.

For reference, the compressive strength of granite is 120 ~ 140 N / mm2, and the compressive strength of loess is about 60 ~ 90 N / mm2. The compressive strength of concrete that can be used as building materials is more than 20 N / mm2 (KS standard).

Therefore, in order to polish the ocher granule mortar with gloss, the compressive strength must be 50 N / mm 2 or more, so that polishing can be polished like marble. However, mortar using general cement hardly meets the compressive strength more than 50 N / mm 2. In addition, the concrete strength using 100% cemented carbide is 340 ~ 375 kg / ㎠, that is, 34 ~ 37.5 N / ㎜ as shown in FIG. It is not enough for marble strength 50 N / mm <2> or more.

As described above, when polishing the ground surface, the clay between the ocher granules and the granules is pulled out, which causes scratches on the ground surface being polished by the missing ocher granules and cement particles. Even if polished for a while, the polished surface cannot be obtained.

therefore. It is very important to find a composition that increases the compressive strength and adhesion strength so that the ocher granules or cement particles do not come out when the ocher granule mortar is applied to the floor and polished.

In Korean Patent Publication No. 10-763654 (published date: 2007.10.4), the applicant's existing patent for mixing with epoxy or urethane resin in ocher particles having a particle size range selected from granules of 1 to 3 mm and 3 to 8 mm When grinding, a large amount of Volatile Organic Compound (VOC) is released and smells. When grinding granules dry, high heat of friction occurs. Epoxy or urethane sticks onto the ocher granules, making it impossible to produce a glossy surface. This method can be used successfully by coating the surface of epoxy or urethane with a thin layer on the flooring after the existing diamond grinding. Since the surface of the ocher granules is not exposed while being polished by grinding like the invention of the invention, there is a limit to being used as a general-purpose material. It cannot be used where there is heating.

In addition, the size of 1 to 3, 3 to 8mm, not 0.5 to 6 mm, as in the present invention, is a powder property. When mixing with epoxy or urethane, an expensive epoxy or urethane is mixed with the powder while soaking the powder. It takes epoxy or urethane, and the color becomes dark brown as the epoxy or urethane gets wet, so that the dark color covers all the beautiful colors of ocher, so it can't make a beautiful surface. Therefore, uniform yellow clay granules of constant size without powder are required.

On the other hand, the ocherite size of 0.5 to 6 mm of the present invention is an ocherite granule containing 0.5 to 1 mm fine powder granules and is automatically filled with fine ocher powder powder granules when filling the pores when mixed with cemented carbide. Since cemented carbide cement is automatically mixed between the granite granules up to 6mm in size and the granules, the small sized ocher granules are combined with the cemented carbide cements between the large sized ocherite granules to act as gravel concrete in a small space. Effective compressive strength is obtained at once. For this reason, the ocher granule compressive strength of the present invention represents 50 N / mm 2 or more of marble strength.

In addition, 0.5 to 6 mm ocher granules and 0.05 mm or less ocher powder are mixed in 90% by weight and 10% by weight to form a granule mortar mixture, which shows a pale yellow loess color. Be in the same context as

As shown in Fig. 4, since ocher is sedimentary rock, dark brown and light brown alternately form a tree ring shape. When grinding, dark brown and light brown of ocher granules alternately appear. At this time, the mixed ocher powder of 0.05mm or less becomes light brown ocher granules and non-colored colors, and the ocher granules contact with each other without the presence of the shoulders.

Therefore, as shown in Fig. 1, the surface area visible to the naked eye is made of only dark brown ocherite granules and light brown ocherite granules, and ocher powder and cemented cement of less than 0.05 mm have light brown color and are in contact with each other. It has a light brown loess color in a very small area between the loess granules, resulting in a high-quality product with a very famous color, such as only loess granules.

The present invention is to solve the problems as described above, the object of the present invention is to apply the ocherite granule mortar on the building floor to cure after the ocher granules and cement particles in polishing the hardened ocher granules bottom surface. It is to provide a loess granule mortar composition and construction method for polished flooring using the loess granules can maintain a firm adhesion strength.

It is another object of the present invention to provide a high quality ocherite flooring product having sufficient surface texture and excellent surface gloss.

Another object of the present invention is to use the ocherite as a building material, the physical properties of the oakstone can be complemented by a binder, which is somewhat insufficient in the physical properties of the building material can be used to expand the scope of use as an excellent building material, and also excellent The purpose of this study is to make effective use of effects and effects in real life residential environment.

The core problem of the present invention is to firstly find the composition range of the polished ocher granule flooring material having a compressive strength of 50 N / mm 2 or more, and secondly, to remove the cemented carbide from the ocher granules and the ocher granules during the initial grinding process. The cement has to be filled up and the next grinding work has to take place quickly. For this purpose, it is necessary to find a composition of ocher powder mortar that can be polished by slightly grinding only the surface during the second and third grinding because the workability is good and the shrinkage does not occur.

An embodiment of the granule mortar composition using the loess granule according to the present invention,

It is a loess mortar composition mixed with 60 ~ 70% by weight ocher granule mixture and 40 ~ 30% by weight cemented cement with 90% by weight of ocherite granule with 0.5mm to 6mm diameter and 10% by weight of ocherite powder with particle diameter of 0.05mm or less. Plastering is performed after 10 days of curing, followed by primary grinding, and mixing 98% by weight of cemented carbide and 2% by weight of polycarboxylic acid as a void due to cemented carbide exiting between yellow clay granules and granules during primary grinding A clay powder mortar mixed with 35 ~ 40% by weight of a cement mixture and 65 ~ 60% by weight of yellow clay powder of 0.05mm or less in diameter is mixed with water, and the slush coating is applied to fill the voids and cured, followed by dry dust grinding. Finishing polished ocher granule mortar flooring.

At this time, since the powder mortar partially fills very little, the grinding strength can be completed if the compressive strength is 30 N / mm 2 or more. Red clay powder 60% cement mixture more than 40% by weight is excluded because of too much cement. It should also be made of very fine ocher powder and cement of 0.05 mm or less, because granules in ocher powder cannot enter micropores and should not cause scratches again.

Yellow clay granule mortar composition mixed with 90 to 70% by weight of yellow clay granule mixture, and 40 to 30% by weight cemented cement, which is mixed with 90% by weight of yellow clay granule having a diameter of 0.5mm to 6mm and 10% by weight of yellow clay powder having a particle diameter of 0.05mm or less The granules are 0.5 ~ 6mm in size and the granules are dongle, so the finished floor is attached to the granules and the granules as if they are shoulders together, and the pores are filled only between the loess granules and the granules. Glossy flooring is completed.

It fills the gap between the ocher granules and the granules with polished ocher powder mortar to fill the gaps left out during the first grinding and maintains the gloss to match the ocher granules. As shown in FIG. 14, the concrete strength using the cemented carbide is 340 to 375 kg / cm 2, that is, 34 to 37.5 N / mm 2.

The 7-day curing strength of cemented carbide cement containing gravel and sand is 36 N / mm2 or less. Mixing cemented carbide cement with ocherite powder yields compressive strength of 30 N / mm2 or more without shrinkage. It is difficult to do. It is surprising to find such a composition only with ocher powder. 35 ~ 40% by weight cemented superhard cement mixture of ocherite powder 65% to 60% mixed with 2% water soluble polycarboxylic acid was mixed with water, slush-coated to fill the voids and cured, followed by second and third grinding Polished ocher granule flooring was completed. At this time, the polycarboxylic acid acts as a water-reducing agent, so the workability is good to fill the voids even with a small amount of water around 20%, so the slush coating does not hesitate after curing, resulting in high gloss with a small number of grinding during the second and third grinding. Finish the work.

At this time, by using a dry grinding grinder equipped with a high-pressure dust collector, it is possible to easily complete the gloss grinding loess granule flooring material by an environmentally friendly method.

According to the present invention, the yellow clay granules are hardened by ultra-high strength cement and hardened for more than 10 days, so that the granules and cement particles are hardly released during dry polishing. Covered by ocher granules, it can provide a high quality bottom surface because it has the same texture as a plate cut from ocher ore.

In addition, since the physical strength of the floor surface is close to the compressive strength of the marble far exceeding the physical properties shown in the cured general cement, it is very useful as a building material.

In addition, the present invention is because the loess and particles of loess are expressed in loess, the efficacy and action of loess is better than loess of raw stone, so when the floor is installed on the floor where the heating pipe is installed, the flooring for heating can be saved significantly. In addition, it can improve the harmful living environment such as VOC, atopic dermatitis, various dermatitis, sick house syndrome, and have the required properties of the building floor.

Hereinafter, the mortar composition using the loess granule for producing a glossy bottom surface according to the present invention will be described in detail.

In order to confirm the physical and chemical properties of the loess granule mortar composition according to the present invention, the samples 1-1 to 2-4 have the same size as the mortar composition mixed with the loess granule of the present invention and the cemented carbide cement under the same conditions. Ready.

Among the constituent materials employed in the present invention, the loess granules are used by crushing those quarryed in rock.

When the ocher granule mortar is prepared by adding water to the loess granule mortar according to the present invention, when the sample is made of mortar, water may affect other compositions (ocherite, cement), for example, curing time and compression of the sample. The amount of water added to each sample was fixed at a constant rate in order to confirm the exact performance of each sample because it may affect the strength, adhesion strength, impact resistance, and the like.

And when the mixing ratio of the loess granules increases, the far infrared ray or anion radiation increases, but the compressive strength, adhesion strength and impact resistance of the cement decrease, and conversely, when the cement is added more than the loess granules, the compressive strength and the adhesion strength Since the impact resistance is increased and the radiation rate of far infrared rays and anions is reduced, the present invention derives the mixing ratio of ocherite granules and cement to express the strength of cement while maximizing the action and efficacy of ocherite, but enhances the strength and adhesion of the binder.

The test report shown in FIGS. 7 to 28 is the compressive strength and the adhesive strength of three samples, and the impact resistance is a test produced by making two samples, and the results described in the test report of Table 1 above are the average values for the same sample. to be.

Looking at the test report of the above [Table 1], the compressive strength is as shown in Figs. 7 to 10, 14 to 17, 18 to 19 and 20 to 24. Attachment strength is shown in Figures 11 to 12, 25 to 28, the impact resistance is shown in Figure 13.

7 to 10 shows the compressive strength of mortar mixed with 80 to 50% by weight of yellow clay granule mixture and 20 to 50% by weight of cemented carbide cement,

11 to 12 shows the adhesion strength of mortar mixed with 80 to 50% by weight of yellow clay granule mixture and 20 to 50% by weight of cemented carbide cement,

Figure 13 shows the impact test results of mortar mixed 80 to 50% by weight ocher granule mixture and 20 to 50% by weight cemented cement

14 to 17 shows the compression of mortar cured with mortar mixed with 80 to 50% by weight of yellow clay granule mixture and 20 to 50% by weight of cemented carbide cement mixture mixed with 10% by volume of cellulose cement to 90% by weight cemented cement. Strength,

18 to 19 show the compressive strength of mortar mixed with 50 to 80 wt% of ocher granules and 50 to 20 wt% of general cement.

20 to 24 are compressive strengths of powder mortar cured with ocherite powder mortar mixed with 80 wt% of yellow clay powder, 98 wt% of superhard cement, and 20 wt% of superhard cement mixture containing 2 wt% of a reducing agent. ,

25 to 26 are adhesion strengths of powder mortar cured ocherite powder mortar mixed with 80% by weight ocherite powder, 98% by weight cemented carbide and 20% by weight cemented carbide mixture mixed with 2% by weight reducing agent .

8 to 10 in the granule mixture of 70 to 50% by weight of the sample 1-2 to 1-4, 30 to 50% by weight cemented carbide cement with compressive strength of 59.4, 60.3, 57.1 N / ㎜ 18 to 19 When the samples 3-1 to 3-3 of the granule 50 ~ 70% by weight, the general cement 50 ~ 30% by weight was significantly higher than the compressive strength 21.5, 22.2, 14.7 N / ㎜.

The compressive strength of 80% by weight of the granules of sample 1-1 and 20% by weight of cemented carbide cement 27.4 N / mm 2 in FIG. It is higher than 5.7 N / mm2 but higher than general concrete strength, but its compressive strength is not so high that it can be polished.

Meanwhile, in FIGS. 14 to 17, the compressive strengths of the mortar obtained by mixing the cementitious cement mixture containing 10% by volume of cellulose cement and 90% by volume of cementitious cement mixture and ocher granules were 30.8, 50.5, 65.9, and 62.9 N. / Mm 2. The compressive strength of Samples 1-1 to 1-4 is equal to or slightly higher than 27.4, 59.4, 60.3, 57.1 N / mm 2.

Therefore, in the sample 1-2, the granule 70 ~ 60% by weight and the cemented cement 30 ~ 40% by weight were maintained at a significantly higher compressive strength as the marble compressive strength of 59.4, 60.3 N / mm2. Can be. At this time, diamond and ceramic pad dry grinding equipped with a high pressure dust collector can produce high strength bottom surface with gloss.

The compressive strengths of 27.4 and 30.8 N / mm 2 were obtained in the samples of 80% by weight granule mixture and 20% by weight cemented cement, which were the composition ratios of Samples 1-1 and 2-1. This compressive strength is not less than the concrete strength, but is not within the composition range of the present invention because it is less than 50 N / mm 2 required for the glossy dry grinding requiring high strength.

Samples 1-4 and 2-4 were excellent in compressive strength of 57.1 and 62.5 N / mm 2, but were excluded from the composition range of the present invention because the ocher granules and the granules should be in contact with each other. When the cement ratio is 50%, the granules and granules are opened when grinding, and the desired shape does not come out, and the marble tone is not beautiful.

The adhesion strengths of Samples 1-1 to 1-4 are as shown in FIGS. 11 and 12.

As shown in FIG. 11, the adhesion strengths of Samples 1-2 to 1-4 showed 2.20, 2.03, and 2.73 N / mm 2, almost equally high adhesion strengths, and that of Samples 1-1 was found in FIG. 12. Similarly, it is slightly lower than 1.5 N / mm 2, but the cement adhesion strength is considerably higher than KS standard 0.8 N / mm 2.

The adhesion strength of Samples 1-2 to 1-4 shows that the cemented carbide cement content is significantly higher, from 50% to 30% by weight, to 2.0 N / mm 2 or more. It fell to N / mm <2>. When the cemented carbide cement content is more than 30% by weight, the physical properties are quite high, but the cemented carbide cement content is gradually lowered at 20% by weight.

Impact resistance of Samples 1-1 to 1-4 is as shown in FIG.

The shock resistance of Sample 1-2 to Sample 1-4 was no abnormality as confirmed in FIG. 13, and Sample 1-1 had an abnormality in impact resistance as confirmed in FIG. 13. If the cement content is 20%, there is a problem in impact resistance. Therefore, it does not fall within the composition range of the present invention.

Far infrared rays, deodorization rate of Table 3, as shown in the sample 1-4 loess granule 50%, cement 50% far infrared ray emissivity is 0.913, deodorization rate is 89%, sample 1-2 ocher granules 70%, far infrared ray at 30% cement Emissivity is 0.917, deodorization rate is 91%. Thus, the far infrared or deodorization rates are excellent for all sample intervals. Therefore, if the compressive strength and the adhesive strength are satisfied, the product composition range can be determined from the composition range.

To summarize the above test results, the useful composition ratio of the loess granule mortar composition according to the present invention satisfies the compressive strength, adhesion strength and impact resistance at the same time 70 to 60% by weight of the loess granule mixture, 30 to 40% by weight cemented cement It was possible to obtain a physical property, which is a key issue that can solve the problem of ocher stone granules and hardened cement particles fall off the bottom surface of the problem to be solved in the present invention in the process of dry polishing the bottom surface. Since the compressive strength of 50 N / mm2 or more and the adhesion strength of 2 N / mm2 or more are obtained, it is possible to grind polished diamonds and ceramic pads in a dry state equipped with a high pressure dust collector.

In other words, 70 to 60% by weight of ocher granules mixture and 10 to 40% by weight of loess powder were prepared by preparing ocherite granule mortar having a composition ratio of 30 to 40% by weight cement. After dry dusting diamond and ceramic pad grinding. At this time, the cemented carbide cement between the granite and the granules partially breaks out to form voids, and if there are many voids, the cemented cement cemented up and scratches the surface of the ocher granules so that the gloss is more efficient. It does not proceed.

Therefore, it is necessary to fill the air gap, which is the position where the cemented carbide cement escapes during the first grinding, and perform the second and third grinding. 20% by weight of water is added to the yellow clay powder mortar in which 35-40% by weight of cement mixture containing 98% by weight of cemented carbide and 2% by weight of reducing agent polycarboxylic acid and 65-60% by weight of loess powder of 0.05 mm or less are mixed. After mixing, apply a slush coating on the pores to fill the pores and cured them. Then, dry dust grinding is performed to complete the polished loess granule mortar flooring.

When the ocherite powder mortar is coated on the whole surface and cured for 3 days or more, the compressive strength is 30 N / mm2 or more at 65 to 60% by weight of ocherite powder and 35 to 40% by weight cemented cement mixture, which is the composition ratio of Samples 4-3 to 4-4. Since it has physical properties of more than 1.1 N / mm2, the high gloss grinding operation does not come out of the ocher granules and the cemented carbide cement particles, which can successfully complete the polished loess bottom surface.

The inventors of the present invention subdivided the samples subdivided by the test method as described above in 70 to 60% by weight ocher granules mixture, 30 to 40% by weight cemented carbide cement blended 90% by weight of the loess granules and 10% by weight loess powder. As a result of manufacturing and testing, it was confirmed that excellent compressive strength, adhesion strength, impact resistance strength, and at the same time, the results of the optimum conditions of optimum ideal with far-infrared emissivity and deodorization rate appeared.

It describes the construction method of loess granule mortar prepared as described above.

First, as the first step, the yellow clay granule mixture of 70% to 60% by weight of the ocher granules and 10% by weight of the loess powder and 30% to 40% by weight of cement cement, mortar 100% by weight of water mortar 100% mortar The mortar mixed in% is plastered on the bottom and cured.

As a second step, primary gloss grinding is performed using a diamond and ceramic pad grinding machine provided with a dry dust collecting cloth. At this time, the cemented cement between the loess granules and the granules is partially separated to form small voids.

As a third step, 100% by weight of mortar to ocher powder mortar mixed with 35 to 40% by weight cement mixture containing 98% of superhard cement and 2% of reducing agent polycarboxylic acid and 65 to 60% by weight of loess powder of 0.05 mm or less in diameter 20% by weight of water is mixed and coated by slush coating on the pores to fill the pores and cure. At this time, the compressive strength of the loess powder mortar used serves as a concrete reinforcing agent for strong surface pore filling with more than 30 N / mm2 and more than 1.1 N / mm2 of bond strength.

As a fourth step, the cured surface is subjected to secondary and third gloss grinding using a diamond and a ceramic pad grinding machine provided with a dry dust collector.

[Picture 2] below is an enlarged photograph of the surface of the present invention, only the ocher granules are visible to the naked eye. Photo 3 is a photograph of the polished and polished surface of the present invention, showing a beautiful appearance.

[Revision under Rule 91 05.10.2011]

Polishing method is to dry with a high-pressure dust collector equipped with a dry grinder, but initially rough grinding with a diamond cup and gradually polished fine ceramic pads to polish the surface. Finishing the gloss completes the desired loess granule flooring product.

Conventional techniques have been widely used in construction of wet diamond grinding, but due to the environmental problems of the sludge from the wet grinding process, the wet grinding process is now almost gone. Nevertheless, if there is a technology to replace on-site watering, it is a technology that flooring is integrated and thus can be said to be preferred because there is no defect in long-term maintenance.

When the ground surface is polished, the surface of the ocher granules 10 is polished as shown in FIG. 3, and the entire bottom surface is not seen as shown in [Photo 2] and [Photo 3]. The natural marble-like texture is expressed. In FIG. 3, reference numeral 20 is cement, and reference numeral 100 is a constructed floor.

The three-day strength of general concrete using 100% of superhard cement manufactured by UNION Co., Ltd. is 340 kg / mm2 (34N / mm2) and 28 days is 375 kg / mm2 (37.5N / mm2). . In Korea, it is a general-purpose material used to manufacture cemented carbide cements from unions and ssangyong cements. That is, even if it is cured for 28 days using cemented carbide cement on gravel concrete, it is only 37.5 N / mm2. When it is cured for 10 days by mixing cemented carbide cement with 0.5 ~ 6mm diameter ocher granule mixture, it is surprising that 59.4 ~ 60.3 N / mm2 Compressive strength comes out. Therefore, it is possible to finish the polished ocher granule flooring by dry dust grinding because more than the strength of marble.

As described above, the present invention can form properties close to the physical properties of marble beyond the physical properties exhibited in the cured cement, the physical strength of the building floor is very useful as a building material, as well as loess particles It has the same effect as the effect and action of ocher stone expressed in ocher ore plate.

Therefore, when the present invention is installed on the floor where the heating pipe is installed, it can not only provide the indoor flooring material for heating, which can greatly reduce the heating cost, but also improve the harmful living environment such as VOC, atopy, various dermatitis, and sick house syndrome. Since the building has the required properties, it can be used as a useful building material.

Ocher granule flooring has a very important characteristic that is not slippery even when wet. Therefore, when used as flooring in churches, schools, apartments, buildings, restaurants, kitchens, large venues, etc., it can be used very safely. It also eliminates odors and maintains a pleasant indoor environment, which provides certain usefulness not only for ground spaces but also for underground spaces.
