[Field of Industrial Application] The present invention relates to a consolidation material that contains amorphous ultrafine particle silica (silica fume) in addition to an alkali metal salt of silicic acid as a silica component, and is mainly used as a ground injection agent. Not only does it have particularly high strength, but it also has high long-term consolidation strength and excellent permeability, and the gelation time can be easily adjusted, that is, high strength can be obtained by adjusting the gelation time to a longer time. Concerning consolidation materials. [Prior Art] Conventionally, cement grout or water glass grout has been used as a chemical for ground injection.
Injection materials containing alkaline solutions of non-colloidal silica, calcium salts, etc. have been known. moreover,
An injection material containing salt and ultrafine silica particles obtained by removing alkali metals from water glass using an ion exchange resin has also been proposed. [Problems to be solved by the invention] However, because cement grout has large particles, it cannot penetrate into fine-grained soil, and the cement content in the grout and mixed water separate in the ground, and this mixture Since water itself does not solidify, the water-stopping effect on sandy ground was insufficient. Furthermore, although the entire blended liquid of water glass grout solidifies, the strength of the gel itself is low, and furthermore, the strength decreases over time, and the shrinkage is large, resulting in insufficient long-term durability. In addition, injection materials containing an alkaline solution of non-colloidal silica and calcium salts not only have an insufficient reaction of the material, but also have an unclear gelation time and tend to leak out of the injection target, and the alkaline content Easy to elute. Furthermore, the above-mentioned injection material containing ultrafine silica and salt cannot increase the concentration of silica, making it difficult to obtain high strength. If too much salt (or base) is used, gelation will occur immediately, making it impossible to obtain high strength over a long gelation time, and furthermore, since an ion exchange resin is used, it will be economically expensive. Therefore, the object of the present invention is to not only exhibit high strength, but also to have high long-term consolidation strength, to obtain high strength by adjusting the gelation time for a long time, and to have excellent permeability. The object of the present invention is to provide a consolidation material which is mainly used as a ground injection material and which has improved the disadvantages of the above. [Means for solving the problem] In order to achieve the above-mentioned object, according to the present invention,
Molar ratio (n=Si0 2 /Na 2 O) of silica content is approximately 1.8
It is characterized by containing the following alkali metal salts of silicic acid and silica fume as essential components, and further containing a polyvalent metal compound or cement as a consolidation agent. The alkali metal salts of silicic acid mentioned above are wavy water glass,
Liquid or powdered water glasses such as sodium orthosilicate and sodium metasilicate, especially with a molar ratio (Si0 2 /
Me 2 O) has a low molar ratio of about 1.8 or less.
However, it is also possible to add an alkali to water glass having a high molar ratio and adjust the molar ratio to a low molar ratio of about 1.8 or less. Silica fume is a byproduct that floats in the exhaust gas generated when silicon alloys such as silicon metal and ferrosilicon are manufactured in electric furnaces, and is extremely small with a particle size of about 0.1 μm and a Blaine specific surface area. It is extremely large at 20 to 23 m 2 /g, and has an extremely high purity of 87 to 94%, and its component composition (%) is Si0 2 : 87 to 94, Al 2 0 3 : 0.6 to 1.4,
Fe203 : 0.5-2.0 , C: 0.8-2.0. When the above-mentioned silica fuyum is mixed with a water glass solution at room temperature, it easily becomes a homogeneous viscous mixture.
This mixture does not precipitate even if left as it is for a long period of time and remains in a suspended state. The reason for this is unclear, but as mentioned above, silica fuum has a very large specific surface area and excellent surface activity, and molecules of dissolved water glass are adsorbed around the silica fuume particles, creating a hydrophilic state and making it stable for a long period of time. It is presumed that this is to maintain a colloidal suspended state. In addition, the polyvalent metal compound used as the solidifying material mentioned above is
Examples include salts of polyvalent metals such as Ca, Al, Fe, and Mg, bases, oxides, and lime (Ca(OH) 2 ) is particularly preferred. The consolidation material of the present invention contains the above-mentioned alkali metal silicate (water glass) and silica fume as essential components as the silica component, and also includes consolidation agents such as polyvalent metal salts, bases, oxides, cement, etc. It is consolidated by adding , and is mainly used as a ground injection material. The content of silica fume is preferably 1 g or more per 100 c.c. of the total consolidation material.
Further, as the silica component, other arbitrary materials (for example, fly ash, diatomaceous earth, etc.) may be used in combination. The above-mentioned consolidation material of the present invention can be used in addition to ground injection.
It is mixed with soil, sand, etc., stirred, or sprayed onto the soil, and used to construct earthen structures and the structures themselves. [Function] As mentioned above, the silica fume used in the present invention is composed of extremely fine particles and remains suspended in an aqueous water glass solution for a long time. This is proven by the following experiment. [Experiment] Silica fuyum and water glass or caustic soda were mixed and stirred in the mixing ratio shown in Table 1.
Slag, fly ash, and diatomaceous earth were used instead of silica fuyume as objects.

It can be seen that even if the caustic soda-consolidating material sample is finally consolidated, the gelation time is extremely long and adjustment is difficult. Example 2 Solution A was prepared as shown in Table 4 by variously changing the molar ratio Si0 2 /Na 2 O of a water glass aqueous solution containing 15 g of solid content in 50 c.c. Solution B was prepared as shown, and the gelation time and daily gel strength qu (Kg/

６に示した。[Table] Tables 4 and 5 show that the gelation time varies depending on the molar ratio of water glass, and as the molar ratio becomes lower than 2.0, the long-term strength increases and the gel strength also increases. This seems to be because silica fuyum is activated by alkali, and the bond between the activated silica fuyum and Ca ions becomes strong. In addition, as a consolidation material, especially Ca(OH) 2 , the gelation time can be easily adjusted from long to short time.
CaCl 2 is suitable for adjusting the gelation time of instant setting, and overall it is suitable for polyvalent metal compounds such as Ca(OH) 2 ,
Compounds that easily supply polyvalent metal ions into water, such as CaCl 2 or cement, are suitable. Example 3 Sodium metasilicate (molar ratio 1.0) as water glass
Also, using sodium orthosilicate (molar ratio 0.5), liquid A was prepared at the mixing ratio shown in Table 6, and liquid B was prepared at the mixing ratio shown in Table 6, and these A,
Measure the gelation time of the mixture of liquid B and show the results in the table below.
