DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to hydrophobicity, weather resistance,
The present invention relates to a building material having excellent durability such as acid rain resistance, a method for producing the same, and a method for constructing floors and walls using the building material.

[0002]

2. Description of the Related Art Conventionally, in the construction of an earth-based floor (earth pavement floor),
Sanshu seed soil (called Sanwa soil in some places) was prepared by adding slaked lime and bitter liquor to weathered granite (commonly called masago soil). In the construction of spring water and floors using Sanshu seed soil, add a small amount of water to Sanshu seed soil, hold it with your hands, knead it to a degree that does not tumble, and strike the kneaded material with a hammer. A method of hardening (beating method) was adopted.

[0003]

However, in the conventional tapping method using the Sanshu seed soil, the type of material to be used is limited, and the work efficiency is reduced because the construction body is constructed while hitting. And that the construction unit price becomes expensive. Further, since the hardening of slaked lime is air-hardened, complete hardening of the construction body requires a long time of about one month, and there is also a problem that the construction period is long. Furthermore, due to the construction method of tapping, uneven filling tends to occur depending on the place,
There was a drawback that durability, especially fluctuation in surface strength, was large. For this reason, the hitting method using Sanshu seed soil was used only for small-scale construction in Sukiya. The present invention has been made in view of such circumstances, using clay, sand and crushed stone obtained from a site close to the construction site, remaining soil at the construction site, excellent workability, does not require a long time to complete hardening, It is another object of the present invention to provide a durable building material and a method for manufacturing and constructing the same.

[0004]

According to a first aspect of the present invention, there is provided a building material for cement, water glass, and water glass hardening, which comprises a plaster portion and a granular material portion. A building material which can be used for a building coating material and / or an earth-covered flooring material, wherein the base material has a stucco part of 10 to 10%.
60% by volume and the remaining part is composed of a granular material part, and the stucco part is mainly composed of lime milk prepared by adding water to quick lime, and has a glue material, a stone powder, and a sua as subcomponents. The part is composed of a first main material mainly composed of aggregate and a second main material mainly composed of clay, and is externally divided with respect to the base material,
3 to 40% by volume of the cement and 0.3 to 30% by volume
Of diluted water glass, and 0.3 to 15% by volume of a hardener for diluted water glass, wherein the diluted water glass contains at least one of sodium silicate, potassium silicate, and lithium silicate.
The hardening agent for diluted water gas is prepared by diluting the stock solution with 1- to 50-fold water. Because the plaster, cement, and multiple hardening materials of water glass are used in combination, even if the form or the material of the first main material and the second main material constituting the granular material portion fluctuates, The adhesive force is stable, and it is possible to reliably cure.

[0005] The reason why the stucco portion is set to 10 to 60% by volume is that if it is less than 10% by volume, it becomes difficult to fill the gaps between the powder and granular material portions to form a dense structure of the construction body. ,
If it exceeds 60% by volume, it takes a long time until the construction body is completely cured. The reason why the cement is set to 3 to 40% by volume is that if it is less than 3% by volume, the effect of improving the strength of the construction body is not exhibited, and if it exceeds 40% by volume, the hue of the building material greatly changes. The reason for using the water glass diluted with water of 1 to 150 times is to effectively disperse the water glass in the base material. When used in a dilution state exceeding, the softness of the building material to be produced becomes too low, and construction becomes difficult. The use of water glass is for accelerating the curing of the building material and improving the adhesive strength. However, when the amount of the water glass used is large, the curing is accelerated and the workability of the building material is reduced. Therefore, in order to promote the curing of building materials and improve the adhesive strength by adding water glass,
When using water glass diluted with 150 times water,
It may be added in the range of 0.3 to 30% by volume based on the base material. The reason for using a water glass curing agent diluted with water 1 to 50 times is to effectively disperse in the base material, the effect of dilution is less in less than 1 time dilution state,
If the dilution state is more than 50 times, the softness of the building material becomes too low, and the construction becomes difficult. In order to sufficiently cure the diluted water glass added in the range of 0.3 to 30% by volume with respect to the base material, in the case of a water glass curing agent diluted with 1 to 50 times water, 0.3 to 15 volumes are used. % Required.

According to a second aspect of the present invention, there is provided a building material according to the first aspect, wherein the first material comprises the first material.
The main material may include sand in addition to the aggregate, and the second main material may include masago in addition to the clay. aggregate,
By using a mixture of sand, clay, and sand, it is possible to adjust the shrinkage, workability, hue, and the like of the building material according to the purpose of use.

According to a third aspect of the present invention, there is provided a building material according to the first or second aspect,
On the base material, a polymer dispersion for cement diluted with 1 to 5 times water is 0.2 to
10% by volume and an antifoaming agent diluted with 1 to 10 times water may be added to the substrate in an amount of 0.01 to 0.1% by volume as an external component. Here, the polymer dispersion for cement is used together with cement during the production of building materials, resulting in insufficient strength of the cement, occurrence of cracks,
A polymer-based admixture for improving poor adhesion and the like. The polymer dispersion for cement is dehydrated to form a polymer film, and this polymer film binds the powdery and granular parts, the stucco part, and the hardened cement. For this reason, various characteristics of the cement are improved, and various characteristics of the building material are also improved. In particular, the combined use of a polymer dispersion for cement can greatly improve the weather resistance and strength of a building material. Further, by adding an appropriate amount of an antifoaming agent, the density of the building material can be improved, and the strength of the building material can be increased.

The reason why the polymer dispersion for cement is diluted with water is to improve the dispersibility of the cement, and it is necessary to dilute the polymer dispersion more than 1 times in order to exhibit the diluting effect. If diluted, the softness of the building material becomes too low, making construction difficult. The effect of adding the polymer dispersion for cement is proportional to the amount used, but too much addition is not preferred because the hue of the building material changes significantly. Therefore, when the amount of cement added to the base material is 3 to 40% by volume, the polymer dispersion for cement diluted with 1 to 5 times water has a range of 0.2 to 10% by volume based on the base material. preferable. The purpose of diluting the defoaming agent with water is to maintain the workability of the resulting building material and to improve the dispersing effect of the defoaming agent. Is preferred.
The amount of the diluted defoamer used is 0.0
The effect appears when added in an amount of 1% by volume or more, but the effect does not change when added in an amount exceeding 0.1% by volume. For this reason, it was made into the range of 0.01-0.1 volume% with respect to a base material.

According to a fourth aspect of the present invention, there is provided a building material according to any one of the first to third aspects, wherein the aggregate comprises pearlite, hill stone, mine stone,
Wood flour, rice husk, glass powder, using a lightweight aggregate consisting of one or more of fine rubber fragments, and further, in the base material, bitterness is 0.2 to 3% by volume with respect to the base material, It is possible to adopt a configuration in which a synthetic paste material is added to the base material in an amount of 0.02 to 0.2% by volume as an external component. Here, pearlite refers to a natural glassy mineral. By using the lightweight aggregate, the weight of the construction body can be reduced. Further, the characteristics of the building material can be changed widely according to the selected material and amount of the lightweight aggregate, and the applicable range of the building material is expanded. By adding bitter and synthetic glue to cement, water glass, and, in some cases, polymer dispersion for cement, it is possible to prevent light aggregate from falling off from building materials and improve workability. In order to improve the holding power of the lightweight aggregate, it is necessary to add 0.2% by volume or more of bitter and 0.02% by volume or more of synthetic paste, but in order not to change the workability of the building material. It is necessary to add 3% by volume or less of bitter and 0.2% by volume or less of synthetic paste material.

According to a fifth aspect of the present invention, there is provided a method of manufacturing a building material, wherein a base material comprises 10 to 60% by volume of a stucco part, and the remainder comprises a powdery and granular material part. Lime milk prepared as a main component, glue material, stone powder, and susa as subcomponents, and the granule portion is mainly composed of a first main material mainly composed of aggregate and mainly clay. A second main material, 3-40% by volume of cement, 0.3-30% by volume of diluted water glass,
3 to 15% by volume of a hardening agent for diluted water glass, and the diluted water glass is obtained by diluting at least one of sodium silicate, potassium silicate, and lithium silicate with water 1 to 150 times, and The hardening agent for diluted water glass is obtained by diluting the stock solution with water 1 to 50 times, and in the method for producing a building material usable for a building coating material and / or an earth floor material, A first step of kneading the part,
A second step of adjusting the base material by adding the granular material portion composed of the first main material and the second main material to the stucco portion, and the cement, the diluted water glass, and the diluted water glass A third step of adding a curing agent to the base material and kneading the mixture.

[0011] The stucco part is adjusted, a main material is added to the adjusted stucco part to synthesize a base material, and then cement, diluted water glass, and a hardening agent for diluted water glass are added and kneaded. By adopting such a mixing and kneading order, it is possible to produce a building material having a small change in workability even if the form or the material of the aggregate or the clay constituting the granular material portion is changed. Become. Further, since the building material can be transported by the mortar pump, the construction unit price is also reduced. Further, since lime milk kneaded with water in advance is used, a hard building material having a low content of carbon dioxide gas can be obtained. Instead of slaked lime used in construction such as conventional tapping, lime milk is used as the main component, and plaster containing glue, stone powder, and sushi is used in advance to improve workability and improve initial strength. , It is possible to produce a building material having a high cost.

Here, as the cement, any one or a combination of two or more selected from ordinary Portland cement, early-strength Portland cement and blast furnace cement can be used. The purpose of using cement is to provide strength to building materials together with stucco. In addition to the cement hardening itself and exhibiting strength, it also acts as a hardener for clay, and ordinary Portland cement and blast furnace cement act as suspension hardeners for water glass in cement. Thus, the hardening of the building material is promoted and the strength is improved. However, since the use of cement changes the hue of the building material, it is necessary to limit the amount of use according to the application.

Water glass is used to harden the clay and increase the adhesion of the building material to the underlying material. The sodium silicate used as water glass is 1
No. 3 and No. 3 are preferred. As the hardener for water glass, inorganic solution type aluminum sulfate, sulfate such as ammonium sulfate, calcium chloride, chloride such as sodium chloride,
Dialdehydes such as glyoxal, which are of an organic solution type, can be used alone or in combination. By selecting a curing agent for water glass, the curing speed can be increased. Therefore, conventionally, it was considered that poor curing or efflorescence occurs when wet with rain within 48 hours after construction. However, in the building material of the present invention, if it does not rain within 24 hours after construction, poor curing or poor curing will occur. It can be cured without efflorescence.

According to a sixth aspect of the present invention, there is provided a method of manufacturing a building material according to the fifth aspect, wherein the first main material includes sand in addition to the aggregate. ,
The second main material may include masago in addition to the clay. By combining the sand with the aggregate as the first main material, it is possible to reduce the mixing resistance when adjusting the base material. Further, by combining masago with clay as the second main material, it is possible to reduce a change in the workability of the building material due to a change in the material of the clay used. Since the viscosity, particle size and other properties of the clay used for the second main material differ depending on the place of origin, it is necessary to improve the clay to suit the intended use. For example, if the viscosity and shrinkage ratio are high, the mixing ratio of sand, sand, and fine stone is increased. If the viscosity is low, adjust the amount of cement, synthetic glue material, water glass, and polymer dispersion for cement to be increased.

According to a seventh aspect of the present invention, there is provided a method of manufacturing a building material according to the fifth or sixth aspect, wherein the aggregate comprises pearlite, hillstone, minestone, Using at least one of lightweight aggregates such as wood flour, rice husk, glass powder, and fine rubber fragments, and further, in a third step, 0.2 to 3 vol. The glue material can be added to the base material in an amount of 0.02 to 0.2% by volume. By adjusting the material and amount of the lightweight aggregate, a building material having a wide range of properties can be manufactured.

According to an eighth aspect of the present invention, there is provided a method of manufacturing a building material according to any one of the fifth to seventh aspects, wherein the third step comprises 1 to 5 times. 0.2 to 10% by volume of the polymer dispersion for cement diluted with water is 0.1% by volume with respect to the base material. .01
０．１0.1% by volume can be added. By using the polymer dispersion for cement together, the action of hardening by cement can be reinforced, and a building material having excellent weather resistance and high strength can be manufactured. As the polymer dispersion for cement, those of vinyl acetate type, ethylene vinyl acetate type, latex type, acrylic type and the like can be used. As the defoaming agent, a polymer surfactant, silicone oil and the like can be used.

According to a ninth aspect of the present invention, there is provided a method for manufacturing a building material, wherein the base material comprises 5 to 30% by volume of quicklime,
The balance consists of a main material containing aggregate, sand, and sand, or further clay, and 10 to 100% by volume of water and 0.02 to 0.3% by volume of the base material. A synthetic glue material;
2-4 volume% bittern, 4-40 volume% cement,
0.4 to 10% by volume of a polymer dispersion for diluted cement, 0.9 to 10% by volume of diluted water glass,
0.9 to 5% by volume of a hardener for diluted water glass, 0.01
And 0.1% by volume of a diluted antifoaming agent, and the diluted water glass is obtained by diluting at least one of sodium silicate, potassium silicate, and lithium silicate with 1 to 10 times water. The hardening agent for water gas is obtained by diluting the stock solution with 5 to 40 times water, and the polymer dispersion for diluted cement is obtained by diluting the stock solution with 1 to 2 times water, and the dilution and defoaming is performed. The agent is prepared by adding 1 to 10
A method for producing a building material having an early strength, comprising a material diluted with double the amount of water and being usable for a building coating material and / or an earth pavement floor material, wherein the quicklime and the main material are A first step of dry-mixing the base material, a second step of adding and mixing the cement and the bitter bite to the base material, and a third step of adding and mixing the water to the base material And a fourth step of adding and kneading the synthetic paste material, the diluted water glass, the polymer dispersion for diluted cement, and the curing agent for diluted water glass and the diluted antifoaming agent.

When water is added to and mixed with quicklime, slaked lime is formed by the reaction of quicklime and water, and large plasticity is exhibited. For this reason, a building material excellent in workability can be obtained. In addition, since heat is generated when quicklime changes to slaked lime, the temperature of the building material increases, and the setting speed of the cement increases, so that a construction body having high early strength can be obtained. Here, the reason for setting the quick lime to 5 to 30% by volume is that if it is less than 5% by volume, it becomes difficult to fill the gaps between the granular material parts and make the construction body a dense structure,
If the content exceeds 30% by volume, the curing speed of the construction body is high, which causes a problem in workability. In order to completely change the quicklime used into slaked lime, it is necessary to add 10 to 100% by volume of water, and if water is added in excess of 100% by volume, the softness of the building material becomes too low, and the construction is performed. It will be difficult.

By adding bitter and synthetic paste, the strength of the construction body can be improved. To improve the strength of the construction body, it is necessary to add 0.2% by volume or more of bitter and 0.02% by volume or more of synthetic paste material. However, bitterness is required to keep the workability of the building material unchanged. Less than 4% by volume,
It is necessary to add 0.3% by volume or less of the synthetic paste material.
The reason for setting the cement to 4 to 40% by volume is that if the amount is less than 4% by volume, the effect of improving the strength of the construction body is not exhibited.
If the content exceeds the volume%, the hue of the building material changes significantly. The reason for diluting the polymer dispersion for cement with water is to improve the dispersibility of the cement, and it is necessary to dilute the polymer dispersion more than 1 times to exhibit the diluting effect. The softness of the building material becomes too low, making construction difficult. The effect of adding the polymer dispersion for cement is proportional to the amount used, but too much addition is not preferred because the hue of the building material changes significantly. Therefore, when the amount of cement added to the substrate is 4 to 40% by volume, the polymer dispersion for cement diluted with water 1 to 2 times has a range of 0.4 to 10% by volume based on the substrate. preferable.

The reason for using water glass diluted with water 1 to 10 times is to effectively disperse the water glass in the base material. If used in a dilution state exceeding 10 times, the softness of the building material to be produced becomes too low, which makes the construction difficult. The use of water glass is for accelerating the curing of the building material and improving the adhesive strength. However, when the amount of the water glass used is large, the curing is accelerated and the workability of the building material is reduced.
Therefore, in order to promote the hardening and adhesion of the building material by adding water glass, when using water glass diluted with 1 to 10 times water, 0.9 to 10 volumes of the base material are used. %
It is better to add in the range. The reason for using the water glass curing agent diluted with 5 to 40 times water is to effectively disperse the water in the base material. If the dilution state exceeds the above range, the softness of the building material becomes too low, which makes the construction difficult. In addition, in order to sufficiently cure the diluted water glass added in the range of 0.9 to 10% by volume with respect to the base material, in the case of a water glass curing agent diluted with 5 to 40 times water, 0.9 to 10% by volume is used. 5% by volume is required. The purpose of diluting the defoaming agent with water is to maintain the workability of the resulting building material and to improve the dispersing effect of the defoaming agent. Is preferred. The effect of the diluted antifoaming agent can be obtained by adding 0.01% by volume or more to the base material, but the effect is not affected by adding more than 0.1% by volume. do not do. For this reason, with respect to a base material, 0.01-0.0.
The range was 1% by volume.

According to a tenth aspect of the present invention, there is provided a method of manufacturing a building material according to the ninth aspect, wherein the quick lime is replaced with one of the quick lime and the lime.
Mixed lime having 0 to 80% by volume and the balance of slaked lime can be used. By using quick lime and slaked lime in combination, the temperature of the building material can be adjusted, and the setting speed of the building material can be adjusted. When the content of quicklime is less than 10% by volume, heat generated when quicklime changes into slaked lime is small, and the temperature of the building material cannot be adjusted. On the other hand, when the content of quicklime exceeds 80% by volume, the effect of using slaked lime is small, and the temperature of the building material cannot be adjusted.
For this reason, the quicklime content in the mixed lime was set to 10 to 80% by volume.

In accordance with the eleventh aspect of the present invention, there is provided a method for constructing a building material according to the eleventh aspect, wherein the building material according to any one of the first to fourth aspects is adjusted to a workable state, and the floor surface is ironed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described to provide an understanding of the present invention. In the method for manufacturing a building material according to the first embodiment of the present invention, a base material composed of 10 to 60% by volume of a stucco part and a balance of a granule part is added to a water diluted with cement and water. Glass, a method for manufacturing a building material in which a water glass hardening agent diluted with water is added and kneaded, a first step of kneading a stucco part, and a second step of adding a powder and granular material part to the stucco part to synthesize a base material. There are two steps, and a third step in which a cement, water glass diluted with water, and a hardening agent for water glass diluted with water are added to the base material and kneaded. In the method for producing a building material, it is important to perform kneading in the above-described process order. Hereinafter, each step will be described in detail.

(1) First Step Powdered lime is put into a slurry adjusting mixer, water is added and the mixture is kneaded well to adjust lime milk. The obtained lime milk is mixed with glue, stone powder and straw as a glue material, and uniformly mixed to adjust the stucco part. As the sizing material, natural sizing materials such as glue and seaweed sizing, and water-soluble synthetic sizing materials such as MC (methyl cellulose) and PVA (polyvinyl alcohol) can be used. can do. In addition,
Synthetic sweets can be used in addition to natural sweets such as hemp and paper peas, and natural sweets and synthetic sweets can be used together.

(2) Second step A stucco part, an aggregate and a first main material mainly composed of sand are added to a mixer for adjusting building materials and mixed until uniform.
Further, a base material is synthesized by adding and mixing a second main material mainly composed of clay and masago. Rather than adding the granular material portion to the stucco part at once, the first main material having a large particle size is added first, and then the second main material having a small particle size is added in order. By employing such a mixing procedure, a base material in which the stucco part, the first main material, and the second main material are more uniformly mixed can be obtained in a short time.

(3) Third Step When the preparation of the base material is completed, ordinary Portland cement is added to the base material, and then diluted with water as diluted water glass.
No.2 sodium silicate, water-dispersed acrylic polymer dispersion for cement, and emulsion-type silicone oil-based defoamer diluted with water, and finally added glyoxal diluted with water as a hardening agent for water glass. And mix until it becomes clear. The production of the building material is completed when the plasticity develops. When adding a polymer dispersion for cement diluted with water, cement, water glass diluted with water, polymer dispersion for cement diluted with water, water glass diluted with water to adjust the pot life of building materials It is preferable to add them in the order of the curing agent. If the hardener for water glass is added before the polymer dispersion for cement, the hardening of the water glass progresses gradually during kneading with the polymer dispersion for cement added, and the resulting building material is obtained. It is not preferable because the pot life of the sample becomes short and the workability decreases.

The relationship between the softness of the building material and the amount of water used is determined in advance, and if the softness is to be reduced (hardened), the dilution ratio of water glass and the hardener for water glass with water should be reduced. Use what you have done. When it is desired to increase the softness, water glass and a hardener for water glass having a large dilution ratio with water are used. For final adjustment of the softness, it is also possible to add water while observing the kneading state in the third step. Further, at the same time as the addition of the antifoaming agent, a predetermined amount of a dispersing agent having an action of peptizing fine powder aggregates can also be added. When the addition of the dispersant facilitates uniform mixing of the fine powder, the amount of water used can be reduced at that time, and a high-strength building material can be obtained. As the dispersant, for example, a polymer surfactant such as polyacrylic acid or sodium polyacrylate, a sodium phosphate-based surfactant, and the like can be used.

Next, as shown in FIG. 1, the building material according to the first embodiment applied to the method for manufacturing a building material according to the first embodiment of the present invention has a stucco part. It has a configuration in which cement, water glass, and a hardening agent for water glass are externally added to a base material composed of a powder and granule portion. An example is shown below. Substrate Plaster part 10 to 60% by volume Powder and granule part 90 to 40% by volume External portion added part Normal portland cement 3 to 40% by volume Polymer dispersion for acrylic cement 1 to 5 times diluted with water 0.2 No. 3 sodium silicate 1 to 150 times diluted with water 0.3 to 30% by volume Glyoxal 1 to 50 times diluted with water 0.3 to 15% by volume Silicone oil (emulsion type) 1 The lime milk which is the main component of the stucco part may be adjusted by kneading slaked lime with water. Lime cream can also be used. The materials used have no special characteristics, so local procurement is possible at the construction site. Also, surplus soil generated at the construction site can be used.

Materials (hardening materials) for imparting strength and hardness to building materials such as cement, water glass, and hardening agents for water glass
Has a configuration in which a necessary amount is added to the base material according to the application. Therefore, it is possible to arbitrarily adjust building materials having different properties such as strength and weather resistance for the same base material. The use of water glass makes it possible to improve the workability of the building material, adjust the curing speed, and perform various types of mechanization (mixing, kneading, transporting, leveling work, and the like of the building material). Also, by using water glass and cement together, construction in rainy weather is also possible.

Depending on the use of the building material, one or more selected from ordinary Portland cement, early-strength Portland cement, and blast furnace cement can be used as a cement. As the water glass, one or more selected from sodium silicate, potassium silicate, and lithium silicate can be used in combination. No. 1 and No. 3 are preferable as sodium silicate. As the curing agent for water glass, use is made of inorganic solution type aluminum sulfate, sulfate such as ammonium sulfate, chloride such as calcium chloride or sodium chloride, or dialdehyde such as glyoxal such as organic solution type alone or in combination. be able to. Further, ordinary Portland cement and blast furnace cement used alone or in combination as cement can also be used as a suspension hardening agent for water glass.

In addition, by using cement and a polymer dispersion for cement in combination, the weather resistance of the building material can be improved, and the strength can be further improved. As the cement and the polymer dispersion for the cement, an acrylic type (solid content 45%), an ethylene vinyl acetate type (solid content 45%), and a latex type which are excellent in alkali resistance are preferable. In order to disperse the cement and the polymer dispersion for cement evenly in the building material, the cement and the polymer dispersion for cement are diluted with water. In addition, it is preferable to use a dispersant in order to facilitate uniform mixing of the fine powder portion in each of the granular materials used and to reduce the amount of water used for mixing and kneading.

Next, the method for manufacturing a building material according to the second embodiment of the present invention comprises the same first and second steps as the method for manufacturing a building material according to the first embodiment. And the third step is different. Therefore, a different third step will be described. In the third step, the base material prepared in the second step is diluted with, for example, early-strength Portland cement as cement and water as diluted water glass.
No. sodium silicate, polymer dispersion for acrylic cement diluted with water as polymer dispersion for diluted cement, emulsion type silicone oil diluted with water as diluent defoamer, bitter, MC as synthetic paste material, for example, MC, dilution As a curing agent for water glass, for example, glyoxal diluted with water is sequentially added and mixed, and kneading is further performed until plasticity is developed. The production of the building material is completed when the plasticity develops. The reason why bitter and MC are added before the glyoxal diluted with water is to slow down the hardening of the water glass and prevent the workability of the building material from deteriorating.

In the above, as the aggregate contained in the first main material constituting the granular material portion, pearlite, hill stone, mine stone, wood flour, chaff,
It is characterized in that lightweight aggregates such as rubber fine pieces are used alone or in combination, and bitterness and MC (synthetic glue material) are further added. By changing the type of the lightweight aggregate and the amount used, various characteristics such as fire resistance, heat insulation, sound insulation, deodorization, and workability such as nailing and sculpture can be imparted to the construction body. In addition, by adding bitter and synthetic glue,
The light aggregate can be prevented from falling off from the building material, and workability can be improved.

An example of a building material using a lightweight aggregate is shown below. Substrate Plaster part 10 to 60% by volume Powder and granule part 90 to 40% by volume External part added part Early strength Portland cement 3 to 40% by volume Polymer dispersion for acrylic cement 1 to 5 times diluted with water 0. 2 to 10% by volume No. 3 sodium silicate 1 to 150 times diluted with water 0.3 to 30% by volume glyoxal 1 to 50 times diluted with water 0.3 to 15% by volume silicone oil (emulsion type) Diluted with 1 to 10 times water 0.01 to 0.1% by volume MC 0.02 to 0.2% by volume Bittern 0.2 to 3% by volume

Having. Hereinafter, each step will be described in detail.

(1) First Step In order to suppress dust, a main material containing quicklime, aggregate, masago, and sand is put into a mixer for adjusting building materials with a lid and mixed in a dry manner. To synthesize a substrate. Note that mixed lime of quick lime and slaked lime may be used instead of quick lime. The mixing ratio of quicklime and slaked lime is determined depending on the curing speed of the building material. In addition, when the temperature is low and the hardening of the cement is slow, the hardening of the cement can be promoted by increasing the ratio of quicklime. (2) Second step A normal mixture of portland cement and bitter is added to the substrate and mixed to prepare a uniform mixture of the substrate, ordinary portland cement and bitter.

(3) Third step Water is gradually added to a homogeneous mixture of the base material, ordinary Portland cement and bitter liquor and mixed to completely convert quicklime into lime milk. To change quicklime into milk of lime, it is enough to add 2.5 to 3.5 times the volume of quicklime used,
Quick lime is converted into milk of lime while gradually adding this amount of water. After the lime milk is generated, water for adjusting the state of the building material according to the purpose of use is further added and mixed. (4) Fourth step When the adjustment of the water content is completed, MC, potassium silicate diluted with water, polymer dispersion for acrylic cement diluted with water, and an emulsion-type silicone oil-based defoamer diluted with water are added. Finally, glyoxal diluted with water, which is a hardening agent of potassium silicate, is added and mixed well, and the mixture is further kneaded until plasticity appears. The production of the building material is completed when the plasticity develops. The MC may be added in small amounts in a powder state, but is preferably added in an aqueous solution state for mixing in a short time.

The purpose of use of quicklime, which is a feature of the construction material according to the third embodiment, is described because it is common to that used in such construction material.

When water is added to and mixed with quick lime, quick lime and water react to form slaked lime and exhibit great plasticity. For this reason, it is possible to obtain a building material having excellent workability such as troweling and crushing. Further, since heat is generated when quicklime changes to slaked lime, the temperature of the building material rises. Therefore, in the construction body using this building material, heat is accumulated inside the construction body, so that the temperature of the construction body increases, and the setting speed of the cement increases. For this reason,
It has the characteristic of hardening in a short time even in winter. Also, instead of using quicklime alone, quicklime is used for 10-80.
It is possible to use mixed lime in which the volume% and the remainder are slaked lime. By using quicklime and slaked lime in combination, the calorific value can be adjusted, and the temperature of the building material can be adjusted. Because it is possible to control the temperature of building materials,
The pot life of the building material can be adjusted, and the applicable range of the building material is expanded.

Coarse aggregates of ３０30 mm are arranged at predetermined intervals, and then the gravel as coarse aggregates is pressed into the floor and / or wall to construct a pavement and / or wall. In addition, as coarse aggregate,
Hard materials such as ceramic fragments, tile fragments, and brick fragments can be used. Pavements and / or walls with different surface properties can be constructed depending on the type and amount of coarse aggregate used. For example, the use of gravel or hard porcelain shards makes it possible to construct a sidewalk that is less susceptible to walking. Also,
The use of brick shards makes it possible to create a sidewalk that has a non-slip function during snowfall or when walking on a slope.

A method for constructing a building material according to a fifth embodiment of the present invention comprises forming a block-like masonry using the building material according to the first embodiment, The timber is laid to build a pavement and / or wall. In the construction material construction method according to the sixth embodiment of the present invention,
By using the building material according to the embodiment of the present invention, the building material is filled in a building mold prepared in advance at a construction site and crushed and formed to form a floor and / or a wall. Since the amount of water in the building material used is small, the curing speed is high, and cracks are unlikely to occur. In addition, when a building material with an increased amount of aggregate is used, the amount of dimensional shrinkage can be reduced. In addition, it is preferable to use glyoxal as a hardening agent for water glass because it has a property of maintaining the hardness of the construction body for a long period of time.

The building materials manufactured in this formwork are put in and polished to build a fence. A suitable amount of the input of the building material per one time is such that the height becomes about 10 to 15 cm in the formwork. If the input amount of the building material is too large, the building material moves in the formwork and is hard to be crushed. If the input amount is too small, the building material must be input frequently and the work efficiency decreases.
In addition, a reinforcing bar and a bamboo bar were used. When the fence was constructed to a height of 50 cm from the foundation, construction of the lower part of the fence was completed.

Using the building material used for the construction of the lower part, the length is 30 cm in consideration of the thickness of the fence, and the length is 10 cm.

Although the embodiments and examples of the present invention have been described above, the present invention is not limited to these.
For example, if the polymer dispersion for cement diluted with water is impregnated from the surface of the leveled floor or wall, the surface of the floor or wall can be further strengthened. If there is no problem in coloring, the hardness of a building such as a floor or a wall can be further improved by adding iron oxide to the building material. In the construction of a fence by the crushing method using building materials, it is also possible to mix and mix aggregates such as tile fragments and cobblestone. Moreover, it is also possible to use a lightweight aggregate as an aggregate in an early-strength building material. Furthermore, by arranging coarse aggregate at predetermined intervals on the surface of the construction body such as floors and walls constructed using fast-strength building materials and pushing it into the construction body, the surface layer characteristics of the construction body can be adjusted arbitrarily It is also possible to do. In the construction of the floor having the stones washed out, small-sized cold gauze can be used instead of the polyethylene sheet. In the third embodiment, the aggregate, the sand, and the sand are mixed as the main materials of the base material. However, clay can be further added.
