2. Description of the Related Art Conventionally, as an inorganic solidified product which can exhibit water resistance and heat resistance, a so-called ceramic body produced by a sintering / melting method requiring high energy represented by tiles, tiles, sanitary ware, glass and the like. No. On the other hand, examples of inorganic solidified products that can exhibit water resistance at normal temperature construction include cement / concrete products obtained by hydraulic processing using Portland cement manufactured by high-temperature clinker processing as a solidifying material, and partially containing hydrous calcium sulfate. Gypsum molded products that are subjected to hydraulic processing using dehydrated calcined gypsum as a solidifying agent may be mentioned.

In recent years, however, there has been a strong demand for regulations such as depletion of petroleum and carbon dioxide associated with global warming, and products made of ceramic bodies and Portland cement manufactured through long-term processing at high temperatures have been developed. They tend to be shunned. Therefore, research is progressing on the production of products by normal temperature processing that can exhibit the same performance as ceramic bodies and cement / concrete products without special consumption of energy.

On the other hand, when treating and disposing of wastes mainly composed of inorganic compounds, in the prior art, incineration ash or molten slag in which the wastes are subjected to sintering means to reduce the volume of the wastes are supplied to a specific control area. Has been dumped. However, dumping of incinerated ash and molten slag is in a direction that is not permissible due to environmental destruction, and a method has been adopted in which these incinerated ash and molten slag are processed into bricks and building materials and reused. However, products manufactured for the purpose of reuse are also limited due to waste, and are also growing in cost, fashion, and preferences, making them reusable products that enable stable production and sales. Absent.

[0005] The method of reusing hydrous muddy mud, etc. is summarized in the "Technical Manual on Construction Generation and Utilization" (published in July 1994) supervised by the Technical Research Office of the Secretary-General of the Ministry of Construction. Guidelines for the reuse of muddy mud etc. are given. In this technical manual, regarding the use of waste soil generated, depending on the properties of the soil and the intended use, "use directly without any modification", "use the properties improved on the generating or using side" However, the technical standards for "utilizing via plants and stockyards" and usage methods for each application such as study procedures are suggested in detail, but are inconclusive.

The following four types of hydraulic solidifying materials are generally given as typical solidifying materials which enable solidification at low temperature at ordinary temperature. A cementing material based on the hydration reaction of hydraulic minerals, mainly calcium salts, which has been proven as plaster and cement. Plaster material based on the hydration reaction of partially dehydrated calcium sulfate that has been used as plaster of Paris in sculptures and tooth molds. Alumina sol-based binder material obtained by alkali neutralization of aluminum sulfate of sulfate bands, which has a proven track record as a water treatment agent. A siloxane-bonded silica-based solidified material formed by polymerization of silanol groups generated by the acid neutralization reaction of alkali silicate, which has long been used as water glass.

Portland cement, a cementing material that has been widely used as a hydraulic solidifying material, is manufactured by a high heat treatment at 1400 ° C. using limestone and clay as main raw materials. Concrete products manufactured with cement are formed from hydrated products of calcium-based minerals by mixing and kneading aggregates and water with cement powder. Widely used in JIS and widely used in JIS.

[0008] However, the production of Portland cement,
Since the material on the alkali side is clinker-treated at a high heat of 1400 ° C, the heat- and alkali-resistant bricks adopted at this time are magcro bricks (mainly composed of chromium oxide and magnesium). It is inevitable that chromium (hexavalent) element, which is a substance, is mixed, and this is a problem (see: Notification of the Ministry of International Trade and Industry on March 24, 2000).

[0009] The cement-based solidified body (concrete) produces hydrated compounds such as calcium silicate hydrate and ettringite by a hydration reaction of the constituent mineral components of cement.
A solid matrix is formed. Therefore, the cement-based solid has no acid resistance, and the hydrated mineral is dehydrated under heating conditions to break the solid matrix, and it is difficult to maintain the solid shape in this state.
Thus, the physical properties of the contreat-based product cannot be expected to be acid-resistant and heat-resistant.

Further, when various aggregates are solidified using cement, and when the organic components such as saccharides and the phosphoric acid components coexist in the aggregates, these organic components and the phosphoric acid components are converted into cement minerals. However, there is a disadvantage that the calcium salt of the concrete is digested, and it is not possible to expect strong solidified properties of the solidified concrete formed here.

As a method for solidifying muddy mud, sludge, soft soil, and even hydrous mud such as volcanic ash clay, hydrated minerals and ettringite are produced by using various cements or improved cements. BACKGROUND ART A technique for modifying soil such as muddy mud with high water content into a solidified body has been disclosed and used as a general technique in the field of civil engineering.

However, if the muddy mud composed of fine particles such as clayey soil, silt, and clay is to be solidified with cement, the soil particle size of the muddy clayey soil, silt, clay, etc., becomes larger. Since the diameter is smaller than the particle diameter, fine soil particles surround the cement particles and hinder the hydration mechanism of the cement, so that good solidification cannot be expected.

[0013] Recently, rivers, bay shores, dams, and other barriers constructed of concrete structures and fishing reefs set on the sea floor are different from barriers and fishing reefs made of natural rocks. It has been found that breeding tends to be suppressed. This, coupled with the reality that cent chromium is eluted from concrete products into the surrounding water system and soil, is limiting the use of cement, and the construction of concrete structures in rivers, bays, dams, etc. Tend to be excluded from the problem.

As a plaster material, calcined gypsum of hemihydrate gypsum obtained by partially dehydrating calcium dihydrate calcium sulfate has been used as a simpler solidifying agent since it forms a solidified product by a hydration reaction. However, in the case of calcined gypsum hydrated gypsum, the shrinkage during solidification is large, a solidified body with high strength cannot be expected, and there is no heat resistance, and its use is limited.

As the alumina sol-based binder material,
A binder effect of alumina sol generated by neutralizing an acidic compound such as aluminum sulfate with an alkaline compound is expected. However, since the neutralization reaction at this time proceeds very quickly, it is difficult to control this neutralization reaction in accordance with the working time, and it is difficult to secure a so-called working pot life, and practical application is not possible. far cry.

As the silica-based solidifying material, an alkali silicate containing a silanol group represented by water glass is generally used. The application as a binder utilizes the formation of a silica polymer composed of a polysiloxane bond of silicic acid formed by adding an acidic solidifying material to a water-soluble alkali silicate and then neutralizing the acid.

Liquid alkali silicate represented by water glass is inexpensive and has a siloxane bond (-Si-
O-) is mainly used in the fields of construction and civil engineering, as well as binders, coatings, adhesives, raw materials for the production of silica gel, structural solids requiring acid resistance and heat resistance, and applications for secondary processed products. Has been used since ancient times.

However, the silica-based solidified material has various problems. For example, a silica-based solidifying material using alkali silicate as a raw material is based on a combination of an alkali silicate and an acidic hardening agent, and has a poor balance between on-site workability and expression of various physical properties of a solidified product. That is, if the work time is secured with emphasis on the workability, the manifestation of various physical properties of the solidified product is poor. On the other hand, if the manifestation of various properties of the solidified product is accelerated, the workability and workability tend to deteriorate.

In the case of these silica-based solidified materials made of alkali silicate as raw materials, water-soluble alkali salts generally remain as by-products in the solidified product formed by being subjected to ordinary temperature construction. There is a tendency. Therefore, when water contacts the formed solid, the by-product alkali salt is redissolved in water to dissolve the silica component, and the water resistance of the formed solid is inhibited, and the solid tends to collapse, Not suitable for outdoor use.

In addition, the water-soluble alkali salt remaining in the solidified product reacts with moisture or carbon dioxide in the air to generate alkali carbonate, and it is inevitable that a so-called whitening phenomenon occurs on the surface of the solidified product. . These problems have not been solved in practical use with silica-based solidified materials made from alkali silicate, and product problems caused by these problems are continually occurring. Commercialization of applying alkali silicate to solidified materials still has many problems. Leaving a point.

As the alkali silicate-based bonding / solidifying material, the present inventors have disclosed, as an invention technique, a combination curing composition of a modified water glass solution and an inorganic phosphate.

As a technique for forming a heat-resistant and water-resistant solid or granule at room temperature using a silica-based solidifying material, a specific aluminate composition is used without using an acidic hardening agent in alkali silicate. A technique of compounding and fixing an alkali component liberated from a formed siloxane bond as an alkali aluminosilicate zeolite or a zeolite precursor and utilizing waste as a recycling material is disclosed in an application patent by the present inventors.

As will be understood from the prior art, waste such as construction waste soil and incinerated ash that have been dumped without consuming a large amount of energy in the treatment and disposal of waste. For example, effective reuse of powdery or hydrous mud-like silicate compositions (incinerated ash, fly ash, slug, construction waste soil, clay soil, organic soil, sludge, soft soil, volcanic ash clayey soil, etc.) The establishment of the technology that allows the solidification is still immature, and the conventional solidification technology at room temperature still has a great problem.

As a method for solving the problem, a method of solidifying wastes with a cement-based solidifying material has been proposed. However, even if solidification of wastes is carried out with cement-based solidifying materials, not only can the harmful substances of heavy metals contained therein be immobilized in a water-insoluble manner, but the harmful heavy metals contained in cement are eluted with chromium, and environmental pollution continues. I have. Moreover, in the solidification treatment and disposal using cement, harmful substances contained in wastes cannot be immobilized in a water-insoluble manner, and this is not a treatment and disposal technique for eliminating environmental pollution. Furthermore, Portland cement and the like require a firing process at a high temperature of 1400 ° C., consume a lot of energy, generate a large amount of carbon dioxide due to decomposition and combustion of raw limestone, and have a negative effect on global warming. Giving a great deal.

On the other hand, there is a proposal to adopt a silica-based solidifying material as a solidifying material and to generate a solidified body by a room temperature solidification treatment technique.
However, there are various problems in the conventional technology of the silica-based solidified material, and a product trouble actually occurs. The main cause of the trouble is that the free alkali component that is by-produced during the formation of the solidified body from the alkali silicate, which is the main raw material of the silica-based solidified material, remains free in the solidified body and causes the whitening phenomenon, as well as water resistance. There is a fundamental problem as a solidified body in which the properties are impaired and the solidified body collapses.

As a means for solving these problems, the present inventors have already sought a siloxane polymer exhibiting a binder effect on the silanol group of the ferrosilicate compound (clay mineral), Technology (Japanese Patent Application No. 2000-3519) developed by developing a binder technology using a silica-alkali composition (Japanese Patent Application Laid-open No. Hei 11-263661), and further using an alkali-based curing agent obtained by combining a silica binder with calcium.
31) has been developed, but is not sufficient in terms of alkali fixation rate.

However, in the prior application development technology,
In the development of the strength of the solidified body to be formed, it is not possible to expect the strength development to the extent that the solidified body by cement shows. Moreover,
The ferrosilicate compound to be specified is used as a solidifying material raw material, and a dangerous and complicated reaction process between the ferrosilicate compound and an alkali component such as caustic soda is required in advance, and all of these factors increase the manufacturing cost of the solidifying material. As a result, the competitiveness of the solidified material in terms of cost has been lost, and technology development for further cost reduction and improved solidified body strength is expected.

To prevent environmental pollution and provide safe, stable and effective products at low cost, for example, for waste recycling without impacting global warming. To contribute.

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors have established a room temperature solidification treatment technology which can solve various problems of conventional room temperature solidification treatment technologies such as Portland cement and water glass, and impede water resistance. It has been determined that it is important to provide a porous solidified body in which the alkaline component to be immobilized is fixed and water resistance and heat resistance can be simultaneously exhibited.

In addition, wastes containing harmful heavy metals are also solidified, and solidification is performed at room temperature, which is low energy, which does not impose a load on global warming. To prevent the spread of environmental pollution
It was determined that it was important to enable the recycling of waste in a safe and stable manner.

The present inventors have proposed, as a prior application technique relating to a solidifying material obtained by solidification at room temperature, a hydraulic silica-based binder containing a specific silica-alkali composition and an aluminate composition as a basic compound (JP-A-11-263661). )
Furthermore, we have developed an alkali-based solidifying agent (Japanese Patent Application No. 200-351931) based on a basic composition of a calcium composition and an alkali composition. We have also developed technology for water-resistant and heat-resistant solidified products, and have achieved commercialization in each field. I have.

Technical conditions and effects of forming a porous water- and heat-resistant solid (E) with an alkali immobilization rate of 25% or more by the above three steps, a step of subjecting the solid to a solid (E) by treatment. Was found.

What is important in the technology of the present invention found here is that the aluminosilicate zeolite, zeolite precursor or non-aluminosilicate is formed by a chemical reaction which occurs when the deformable admixture (D) of the present invention is subjected to room temperature solidification treatment. A crystalline aluminosilicate (hereinafter, these are collectively referred to as "zeolites") is formed.

The advantages of the formation of zeolites and the solidification (E) of the present invention in which zeolites are formed are as follows:

First, it reacts with the silica component in which the alkali component of the room temperature hydraulic hardening material (A), which has been made into one pack, coexists, and the silica component of the silicate material (B) to be solidified. Generates activated silanol groups in the silica component. Starting from the silanol groups of the activated silica, alumina and alkali components are added to the reaction to form zeolites. In parallel with the formation of zeolites, condensation occurs due to the dealkalization reaction of the silanol group, and a polysiloxane bond serving as a solidified base is formed, thereby exhibiting heat resistance. On the other hand, by the generation of zeolites, the alkali component is immobilized in the solidified body in a free state without being preserved (an alkali component immobilization rate is improved), and water resistance is exhibited.

Further, the importance of the formation of zeolites in the solidified product (E) formed by the technique of the present invention is based on the fact that wastes containing harmful heavy metals coexist with the calcium composition (A).

Examples are alum composition (AA1) containing aluminum sulfate as a main component, gypsum composition (AA2) containing calcium sulfate as a main component, and sodium sulfate type composition (AA3) containing sodium sulfate as a main component. Four types of the composite composition (AA4) can be mentioned.

The sulfur oxyacid salt composition (AA) of the present invention
As alum type composition (AA1) in the following composition formula ^{_{(1) aM I 2 O ·}} bM III 2 O 3 · SO n · wH 2 O ‥‥‥‥‥‥ (1) ( wherein: ^{M I} is An alkali metal element, M ^III is a trivalent aluminum or iron element, a is a number of 0.2 to 20, b is a number of 1 to 20, w is a number of 25 or less including zero, and n is a number of 2 or 3 Alum-type composition (AA1) composed solely or in combination of two or more selected from the group consisting of double salts of oxyacid salts of aluminum or iron sulfur containing a basic salt or a normal salt of an alkali metal represented by the formula (A1)
Can be suitably mentioned.

In general, as an alum-type composition (AA1), as an oxyacid salt of aluminum or iron sulfur which is an alkali metal element, octahedral K ₂ SO ₄ ·· formed from a mixed solution of aluminum sulfate and potassium sulfate is used. Al
A double salt crystal of ₂ (SO ₄ ) ₃ .24H ₂ O is typical. In addition, as the sulfur oxyacid salt (AA) of the present invention, aluminum sulfate or iron sulfate in which c in the formula (1) is zero can also be suitably used.

In particular, in the present invention, the formation of a zeolite is expected in the formed solid, and therefore, the aluminum element is an essential component of the solid. Generally, the aluminum element is contained in the silicate-silicate material (B) to be solidified, but the aluminum component of aluminum sulfate, which is the alum-type composition (AA1), is supplemented as the aluminum raw material of these zeolites. It is effective from that.

Furthermore, in the formation of a solidified body in the present invention, even when heavy metals are contained in the raw material, the heavy metals can be immobilized in a water-insoluble manner by the formation of zeolites. In combination with this phenomenon and the functionality of the arsenic-immobilized composition (C3) of the functional addition composition (C) to be described later, if iron ions coexist in the room-temperature hydraulic setting material (A) of the present invention, It is effective for water insolubilization of heavy metals such as arsenic and chromium, and the coexistence of iron sulfate is effective for the room-temperature hydraulic hardening material (A) of the present invention.

The sulfur oxyacid salt composition (AA) of the present invention
Plaster type composition (AA2) as the following composition formula _{(4) aCaO · bMgO · SO} n · wH 2 O ‥‥‥‥‥‥ (4) ( wherein in: number from a no 1 20, b is zero A ≦ b, w is a number of 2 or less including zero, and n is a number of 2 or 3) Basic sulfur or normal salt calcium represented by the following formula: Gypsum-type compositions (AA2) composed of one or a combination of two or more selected from the group of the oxyacid salts of (a).

Calcium sulfate is typically classified into three crystal forms, dihydrate, hemihydrate and anhydrous salt, and further classified into two types of hemihydrate and four types of anhydrous salts, for a total of seven types. Is known.

The hemihydrate calcium sulfate is dehydrated by giving each heating condition between 60 ° C. and 150 ° C. to obtain α-type and β-type hemihydrate sulfate. Calcium (gypsum) is produced. In addition, calcium sulfate, a hemihydrate salt, is heated to 105 or 1200 ° C.
By giving each heating condition between the above, calcium sulfate of four kinds of anhydrous salts, so-called calcined gypsum is formed.

Each gypsum has a certain solubility and is soluble in water. In particular, calcined gypsum of hemihydrate gypsum returns to calcium sulfate of dihydrate when mixed with water, and forms a solidified body. Therefore, gypsum is widely used as various mold materials and plaster plasters.

However, anhydrous gypsum, which has been dehydrated by being heated to 200 ° C. or more, has low water solubility even when mixed with water, hardly adheres hardly, and generally hardly forms a solid. Anhydrous gypsum on the alkali side as in the present invention reacts and effectively exerts its effect as a solidifying material component.

It is economically effective as a raw material.

, W is a number of 20 or less including zero, and n is a number of 2 or 3) selected from the group consisting of alkali metal sulfur oxyacid salts which are lithium, sodium or potassium of a basic salt or a normal salt.

The oxyacid compound of each element of the alkali metal may be in the form of a solution previously dissolved in water as long as the physical properties required for the room temperature hydraulic hardening material (A) of the present invention are not impaired.

[0150] In a further aspect of the alkali composition constituting cold hydraulic solidifying material (A) of the present invention (AB), the basic composition is represented by the following formula _{^{(7) M I n Z ·}} wH 2 O ... ...............

At this time, a in the composition formula (8) is 1.8
If it is smaller, the amount of the alkali component is too large, and the curing speed of the solidified product is retarded, and the solidified product tends to exhibit a whitening phenomenon, resulting in poor water resistance. In addition, a is 3.
When it is more than 5, the amount of the reactive silanol group becomes small, and the formation of an effective polymer composed of siloxane bonds is not expected, and a solid having a high hardness tends not to be obtained.

In the composition formula (8) of the alkali silicate composition (AB4), when w is in the range of 3.0 to 50.0, the alkali silicate is a liquid, and the alkali metal silicate It is suitable as a raw material for the composition (AB5).
When sodium silicate is a so-called liquid water glass, J

The alkali salt required for forming the silica polymer which is to be a composite matrix of the solidified product formed in the above can be rich in silanol groups.

Generally, the hydrous phyllosilicate mineral is Si-
A clay composed of a water-containing layered silicate compound based on a layered silicate structure bonded to each other around a tetrahedron of O is a general term, and a natural layered clay mineral corresponds to this. These phyllosilicate minerals are roughly classified into a hexagonal mesh layer and a square mesh layer, and most ferrosilicate compounds are formed from a hexagonal mesh layer.

According to the classification of the layered clay mineral which is a hydrous ferrosilicate mineral, kaolinite of 1: 1 layer type is classified into a dioctahedral type and a trioctahedral type. On the other hand, the 2: 1 layer type includes groups such as pyrophyllite, talc, smectite, vermiculite, mica, and chlorite.
It is classified into an octahedral type and a trioctahedral type.

Among them, layered clay minerals such as 2: 1 layer type smectite group octahedral montmorillonite and beidellite have a higher bond between aluminum and silicon than layered clay minerals such as 1: 1 layered kaolinite.

In this montmorillonite, the distance between positive and negative charges is large, the interaction force is weak, and cation exchange is easily caused to form an alkali silanol group exhibiting a binder effect, which is preferable.

The layered clay mineral (ABS2) composed of these ferrosilicate minerals has the content and amount of the metal element partially substituted depending on the place of production, the environment at the time of clay formation, and the like.
In addition, the amount of water coordinated between the layers may change, and there is a tendency that the distance between the bottom surfaces is changed by the metal element to be replaced and water or organic matter entering between the layers, which also affects the development of swelling property There is a tendency. Montmorillonite is classified into bentonite and sub-bentonite (acid clay), whose swelling property is not so large.

Therefore, in the present invention, in the case of a water-containing layered clay mineral coexisting with impurities, if the clay mineral contains at least 50% by weight or more of an active ingredient as a clay mineral, for example, montmorillonite, the object of the present invention is considered.

In this case, the simple powdered barium silicate is
The g number in the composition formula (16) is preferably a number of 4.0 or less, and if it is 4.0 or more, the activity of barium ion cannot be effectively used. Further, the number w of the composition formula (16) is preferably not more than 9.0, and when the number is not less than 9.0, the storage stability of the barium salt compound in a one-pack product is particularly ensured in the present invention.

In the body, since the alkali component is immobilized with zeolites, it is possible for glass fibers to be appropriately adopted without deterioration.

The cold hardening material at normal temperature (A) of the present invention is very effective as the hardening material described in (1).

The “aggregate” at this time is classified into “fine aggregate” made of sand and crushed stone having a particle size of 5 mmφ or less and “coarse aggregate” made of gravel and crushed stone having a particle size of 5 mmφ or more. In the present specification, `` coarse aggregate '' is regarded as pure expanded aggregate, and the effect of adopting coarse aggregate is common general knowledge in the industry, and does not impair the essential properties of the water-resistant and heat-resistant solidified body. Therefore, the adoption of "coarse aggregate" is not incorporated into the sandy silicate-based material (AS) of the present invention unless otherwise specified.

As another form of the functional additive composition (C) adopted in the present invention, the above-mentioned additive material composition (C

Can be mentioned. This mixed raw material composition (C8) is preferable because a plurality of additional raw materials are composited, whereby the composite properties as the additional raw material, the mixing effect, and the composite / mixed synergistic effect are sufficiently exhibited.

The fluid or plastic deformable admixture (D) in the present invention is a basic admixture of a two-part admixture of a room temperature hydraulic hardening material (A) and a silicate material (B) to be solidified. And a three-part admixture of the two-part admixture and the functional addition composition (C) as required as an additional admixture;
The effect of the deformable admixture (D) of the present invention can be effectively exhibited to form a solidified body (E), thereby achieving the object of the present invention.

In the present invention, the two-component deformable admixture (D) is prepared by mixing 100 parts by weight of a four-pack or five-pack one-pack normal-temperature hydraulic hardening material (A) with the silicate to be solidified. Addition of 1 to 2,000 parts by weight of the salt-based material (B) and 1,000 parts by weight or less of the aqueous composition (AD), and homogenous mixing, thereby ensuring fluidity or plastic processing and workability. It is prepared by making a mixture of

In the present invention, the deformable admixture (D) prepared by mixing the functional addition composition (C) together with the tripartite admixture is:
For 100 parts by weight of the deformable admixture (D) of the mixture of the two,
It is prepared by adding the functional additive composition (C) in an amount of 1000 parts by weight or less and uniformly mixing to obtain a three-part admixture in which fluidity or plastic workability is ensured. At this time, even if the mixture is powdery and rough, if the mixture is integrated by external pressure and plasticity is obtained, it is effective as the deformable mixture (D) of the present invention.

Each of the functional additive compositions (C) co-mixed in the present invention can be separately mixed with the silicate-based material (B) to be solidified, but the room-temperature hydraulic hardening material (A) ), A sulfur oxyacid salt composition (AA), an alkaline solution (AB), a calcium composition (AD), an aqueous composition (A)
D), a solidification auxiliary composition (AE), and if necessary, a pre-mixing and mixing with another functional additive composition (C) to form a one-pack, and then preparing a deformable admixture (D). This is also effective for work efficiency.

However, the alkaline composition (AB) and the calcium composition (AC) constituting the room temperature hydraulic hardening material (A)
When an easily reactive silicic acid or silicate coexists, the silicate-based material (B) does not need to be coexistent, and a four-part or five-part normal-temperature hydraulic hardening material (A) is used. Preparation of the deformable admixture (D) by itself is also possible.

The method for preparing the mixture of the deformable admixture (D) of the present invention varies depending on the purpose and use of the solidified product (E) in the present invention, the required performance and function, and the like. Using a mixer, a stirrer, a kneader, a disperser, and other commonly used mixers commonly used in the industry, the components are appropriately selected and selected from methods capable of uniformly mixing or kneading the components of the raw materials. This is easily achieved by:

Generally, in order to prepare the flowable or plastically deformable admixture (D) of the present invention, kneaders, mixers and the like generally used in the processing of cement milk, concrete secondary products and the like are used. A dispersing machine can also be suitably adopted. In addition, depending on the purpose, an injection device or a filling device of a solidification material such as a deep mixing method which has been widely used in the civil engineering industry such as ground improvement can be suitably adopted.

In addition, when the deformable admixture (D) of the present invention is admixed, an aqueous composition (AD) is further added and blended, whereby the admixing conditions are improved and the work efficiency of the admixing process is improved. However, it is generally necessary to pay attention to increasing the blended water content to the deformable admixture (D) since the strength of the solidified body (E) tends to decrease.

In general, the solidified product (E) of the present invention is prepared by mixing the flowable or plastically deformable admixture (D) of the present invention at 80 ° C.
Hereinafter, it can be preferably achieved by a room temperature solidification treatment step, which is a reaction / curing treatment step of releasing into the air or water in the range of 10 to 80 ° C. In this room temperature solidification treatment step, there is no special meaning to limit the treatment temperature to 10 ° C. or more, but if the treatment temperature is 10 ° C. or less, it is not impossible to form a solid (E) of the deformable admixture (D). However, it takes time to form the solid (E), which is not preferable in terms of working efficiency.

However, the temperature condition at the time of release to the atmosphere or water in the room temperature solidification treatment step is not particularly limited to 80 ° C. or less in the atmosphere, but may exceed 400 ° C. from the viewpoint of workability and productivity. It is also possible to carry out the solidification treatment by controlling the leaving atmosphere within a range that does not exist.

Although it is not impossible to perform the treatment at a treatment temperature of 400 ° C. or higher, there is no particular advantage.
Rather, it is not preferable because heat energy is wasted. However, when the quality of the solidified product (E) is required to change with the productivity or the condition requiring heating in the production line,
It is preferable that the solidification treatment is performed in an atmosphere of 400 ° C. or less, which does not hinder the formation of a composite solidified matrix of a silica polymer or an aluminosilicate generated under this temperature condition, and is rather preferable in terms of improving productivity. is there.

There is no particular advantage even if the solidification treatment conditions are set to 400 ° C. or higher. However, when processing the solidified product or the like produced on the production line, the solidification target material contains an organic component, or When improving the performance, strength, etc. of the resulting solidified product, release of the product to a high temperature of 900 ° C or less can carbonize or decarbonate the contained organic components. It does not hinder the basic reactions and steps of the room temperature solidification treatment technology of the invention.

Furthermore, the deformable admixture (D) of the present invention
Is subjected to room temperature solidification treatment at room temperature of 80 ° C. or lower or in a range of at least 400 ° C., and various conditions such as pressurization, depressurization, vibration, pouring, pushing, pouring, as well as atmospheric pressure in the atmosphere. Can be implemented. Under curing conditions, not only room temperature curing but also heating curing, steam curing,
