1313673 (1) IX. INSTRUCTIONS OF THE INVENTION [Technical Fields of the Invention] The present invention relates to an effective use of blast furnace smog and a widely used improvement in site improvement works and water stop projects in the civil engineering, construction, and construction industries. A material composition, a method of preparing the same, and a potting material using the same. [Prior Art] Φ In recent years, environmental problems have grown tremendously. In particular, various attempts have been made to effectively utilize industrial by-products. Among them, blast furnace slag, fly ash, or ash has established many effective utilization methods, for example, a large amount of mixed use in Portland cement, and has also been formulated in JIS. However, there are many industrial by-products that have not yet established an effective utilization method, and the establishment of their use methods is strongly demanded for the construction of a recycling-oriented society. One of them can be cited as blast furnace smog. Blast furnace smog is a by-product of the steel manufacturing process. It is the ash that obtains Φ pig iron to collect dust from the blast furnace. The effective use of blast furnace smog has been proposed as a mixed material for use in a glass fiber reinforced cement composite (see Patent Document 1 and Patent Document 2). However, alkali metals are contained in the components of blast furnace smog, and the current situation is difficult to use in concrete due to fear of alkali-bone reaction, and it is desired to establish a utilization method. On the other hand, materials for improving the site are widely used for improving site engineering and water stopping projects. The so-called improved site construction refers to the construction of the site of the site of the large-scale special structures such as dams and power plants, tunnels, and -5- (2) 1313673 oil and LPG reserve bases. The project of injecting the improved site through the liquid medicine during the construction of the material. The so-called water stop project refers to the prevention of flooding of water into the infusion material during the construction of underground structures below the groundwater level, under the sea, and in the water-bearing site, and in order to improve the site, Watertightness and infusion of materials for improved site materials. In addition, there are also sites for the improvement of the general construction of houses and buildings such as sites with poor drainage and liquid-distributed sites, and the prevention of site collapse in basic facilities such as water and sewage. The material for the improved site is widely used in such projects, and is a material used for the purpose of commanding the site to be fixed and being strengthened by compaction and dehydration. Next, the specific examples of the above-mentioned materials for improving the flooring and the works using the same will be described. For example, in the coverage of a tunnel, a void sometimes occurs on the back of the covered concrete during construction and after construction. If the hole is placed as it is, then # With the collapse of the ground high object for the cavity, the surface of the ground sinks. In the case of high ground mass collapse, deformation and damage of the covered concrete occur, in particular, tunnel collapse occurs, and the inflow of groundwater into the cavity causes the concrete to deteriorate, and the accompanying deterioration causes the concrete piece to fall toward the lane, and Water leakage in the cracks caused problems such as freezing of the winter traffic lanes. In the tunnel repairing project in which the number of constructions has increased in recent years, the infusion material is filled in the cavity covering the back of the concrete, and the tunneling method is used to stabilize the tunnel. The infusion material used herein is referred to as a wrap material, and cement-bentonite has been used in the past. However, it has excessive fluidity -6-(3) 1313673, and the wrapped material unnecessarily escapes when it reaches the far side. If there is water inrush, the material is swept in, and the material is diluted to reduce the physical properties. Then, it is proposed to add a high water absorbency resin to the main material of cement and bentonite to increase the viscosity thereof, and a method of adding water glass to promote hardening (see Patent Document 3 'Patent Document 4). However, any of the methods must take time to increase the viscosity, and the method of adding the super absorbent resin is that the superabsorbent resin itself is expensive. When φ and 'the initial injection into the potting material and kneading, the viscosity of the main material becomes high', so the pressure feed distance has to be shortened, and there is a problem that the filling place is limited. On the other hand, in the method of adding water glass, since the enthalpy of the water glass is strongly alkaline of 13 or more, the operation is considerably restricted, the falling water from the hardened body imposes a burden on the environment, and the long-term strength of the hardened body is lowered. And other issues. Moreover, recently, a method for solving the problem of the wrapped material has been proposed. In the main material of cement-bentonite and cement-stone carbon ash (fly ash), adding a polymer as a plasticizable material enables instant plasticization and improvement in water. Non-separability and safety (see Patent Document 3, Patent Document 5, and Patent Document 6). On the other hand, in order to obtain the reinforcing effect and the water stopping effect of the ground, a potting material using cement is used (refer to Patent Document 7). However, in the case where the geological is fine sand, sludge, or clay, there is a problem that the permeability to the ground is small, and the perfusion is difficult. Patent Document 1: JP-A-2002-47037 (4) 1313673 Patent Document 2: JP-A-2004-67477 Patent Document 3: Japanese Laid-Open Patent Publication No. Hei No. Hei No. Hei. Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The present invention is an improved site material which can be widely used in a site improvement project, a water stop project, and the like, and particularly provides a material for an improved site which is excellent in permeability and durability by using blast furnace fly ash in which no effective use method is found. The composition, (2) is superior to the long-distance pressure-feeding property of the potting material using bentonite and superabsorbent resin, and is rapidly thickened by adding a plasticizable material. For example, a void-filled material that is wrapped in a material or the like is reached. It will not be unnecessarily escaping in the distance, and even if there is water inrush, it will not flow out of the void filling material, and will not be diluted to reduce the physical properties. Moreover, the water-like dissolved water will not become strongly alkaline.

In terms of hardening time and strength performance, it is preferable to select an amorphous material having a Ca0/Al203 molar ratio of 1 to 2. The glass transition rate of CA is obtained in the same manner as in the case of CAS described above, and is obtained by X(%)=100x(lS/SQ). However, S and S〇 are obtained in the same manner as in the case of CAS. In terms of more than 50%, it is better to use 80% or more, and more preferably 90% or more. If the temperature is less than 50%, the short-term strength is small. CA is to rotate the CaO raw material and the Al2〇3 raw material. The raw material for the production of CA is not particularly limited, and examples thereof include calcium carbonate such as limestone and shells, hydrated lime, and quicklime as CaO raw materials, and examples of the AhC»3 raw material include, for example, Boxide. In addition to the industrial by-products of the aluminum residue, aluminum powder, etc. may be mentioned. The amount of CA used is preferably 1 part by weight with respect to blast furnace smoke, and more preferably 5 to 30 parts. If the amount is less than 1 part, the short-term strength is small, and if it exceeds 50 parts by -22-(19) 1313673, the viscosity of the infusion material becomes a large suspension, and the permeability to the ground plate is lowered. Further, in the above aspect of the present invention Examples of the gypsum used in the infusion material include anhydrite gypsum and hemihydrate gypsum 'dihydrate gypsum. Furthermore, it is possible to use natural gypsum, phosphoric acid to form gypsum, gypsum, sulphuric acid by-product gypsum, or the like, or gypsum obtained by heat-treating the gypsum, etc., wherein the water is anhydrous in terms of high performance. Gypsum is preferred. φ gypsum is used in an amount of 1 part to 50 parts per blast of blast furnace smoke, preferably 5 to 50 parts. If less than 1 part, the short-term strength is small, if more than 50 parts Further, the permeability to the ground plate is lowered. Further, the alkaline stimulating material used in the above-described infusion material of the present invention contributes to hardening and long-term strength by being used in combination with blast furnace smog. Examples of the alkaline stimulating material include alkali metal hydroxides such as sodium hydroxide, potassium hydroxide, and lithium hydroxide; alkali golds such as sodium carbonate, potassium carbonate, and lithium carbonate; and hydrated lime. Although it is not particularly limited, it is preferable that the stone is ash by the hardening caused by the blast furnace smog and the increase in the long-term strength. The amount of the alkaline stimulating material used is 1 part by weight relative to the blast furnace smog, preferably 1 to 50 parts, and more preferably 3 to 20 parts. If the amount is less than 1 part, the long-term strength is small, and if it exceeds 50 parts, the permeability to the site sometimes decreases. In the present invention, the maximum particle diameter of the infusion material is preferably 20 μm, and more preferably 15 μπι, and most preferably 10 μιη or less. If it exceeds 20 μm, it may become difficult to permeate the fine gap depending on the geology of the site. V'..: -23- (20) 1313673 The method of preparing the particle size of the infusion material is not particularly limited, and each material may be pulverized by a pulverizer such as a ball mill, and collected under a fraction of 20 μm or less, and After mixing, or mixing and pulverizing the materials, • and collecting any of the methods of .2 〇μm. However, if the materials are mixed, pulverized, and classified, the mixing ratio may be changed due to the difference in density of the materials. Therefore, it is preferred that the materials are separately pulverized and classified and thereafter mixed. Further, in the present invention, in order to adjust the hardening time required for the adjustment, it is preferred to use a coagulation adjusting agent. Examples of the coagulation adjusting agent include aluminates such as sodium aluminate and potassium aluminate, carbonates such as sodium carbonate and potassium carbonate, hydroxides such as sodium hydroxide and potassium hydroxide, aluminum sulfate, and iron (III) sulfate. Inorganic salts such as citrates such as sulfates, sodium citrate and potassium citrate, phosphates such as sodium phosphate, calcium phosphate, and magnesium phosphate, and borate such as lithium borate and sodium borate And organic acids such as citric acid, gluconic acid, tartaric acid, and malic acid or sodium, potassium, and calcium salts thereof, or metal salts thereof, and saccharides. It is possible to use one or more of them. Among them, carbonic acid salts and organic acids are preferred for ensuring the hardening time required. The amount of use of the coagulation adjusting agent is not particularly limited as long as it is adjusted according to the curing time. However, it is preferably from 0. 1 to 10 parts, and from 0. 5 to 100 parts of CAS, or a total of CA and gypsum. 5 servings are better. If it is less than 0 · 1 part, it is sometimes difficult to ensure the hardening time. If it exceeds 10 parts, the hardening time becomes longer and the strength becomes smaller. In order to improve the permeability in the ground, in the present invention, it is preferred to use a dispersant for -24-(21) 1313673. Examples of the dispersant include a naphthalenesulfonic acid formaldehyde condensate salt system, a lignosulfonate system, a melaminesulfonic acid formaldehyde condensate salt system, a polycarboxylate system, and a polyether-based dispersant. The dispersant is used in an amount of from 1 to 10 parts per blast of the blast furnace, preferably from 0.1 to 1 part by weight, more preferably from 0.5 to 3 parts. When the amount is less than 0.1 part, the permeability is small, and if it exceeds 10 parts, the strength sometimes becomes small. The amount of water when the infusion material is used as a suspension is not particularly limited as long as the suspension can be pumped by a pump, and the total amount of the blast furnace smoke, CAS or CA, gypsum, and alkaline stimulating material is 100, to 100. ~ 1,000 servings are preferred, and 200 to 500 servings are preferred. When the amount is less than 1 part, the viscosity of the suspension becomes high and the permeability is small. If it exceeds 1, the strength sometimes becomes small. The mixing method and the infusion method of the infusion material are not particularly limited, and the single-pipe material method, the single-tube filter method, the double-tube single-phase method, the double-tube multi-phase method, and the double-tube double-packer method can be applied. Construction method. EXAMPLES Hereinafter, the present invention will be specifically described based on examples, but the present invention is not construed as being limited thereto.
