れる。The alkaline earth metal salt of carbonic acid is suspended in the aqueous solution of water glass but gradually precipitates. However, since the precipitated alkaline earth metal salt of carbonic acid can be easily returned to the original suspension state by stirring at the time of use without solidifying, it can be preliminarily blended prior to injection. It is also possible to add a small amount of a suitable dispersant such as a surfactant to this system to prevent sedimentation. Examples of the alkaline earth metal salt of carbonic acid include calcium carbonate and magnesium carbonate.

とも可能となるものである。The present invention is a system consisting of water glass and an alkaline earth metal salt of carbonic acid, which does not show any reactivity directly, rather than adding an alkaline earth metal salt of carbonic acid to a mixed system of water glass and an alkali metal aluminate salt. It was completed by discovering that the addition of an alkali metal aluminate solution to the solution ideally induces a reaction as grout to form a stable bond between silica, alumina, and calcium. It is also possible to accurately mix water glass and calcium carbonate, carry them into the site, and perform the construction easily and accurately at the site.

This is an example of a liquid, No. 2, 3 corresponding to No. 1, No. 5, 6 corresponding to No. 4, No. 8 and 9 corresponding to No. 7 are water glass and sodium aluminate solution. Liquid A is a system of water, sodium aluminate solution, calcium carbonate and water.

In Nos. 5, 6, Nos. 8 and 9, the caking strength is obviously lower than Nos. 1, 4, and 7 according to the present invention. In addition, the gelation time is shortened, and immediately after the liquid A and the liquid B are merged, the viscosity is rapidly increased in a suspended state, and the permeability is extremely poor.

In the case of 0.2 or less, the consolidation strength is inferior. No.11 ~ No.22
Then, the value of [CaCO 3 ] / [Na 2 O] is in the range of 0.2 to 1.0, and most of them, especially [CaCO 3 ] / [N

In No. 15 and No. 18, the values of [CaCO 3 ] / [Na 2 O] are in the range of 0.4 to 0.8, but the strength is considerably poor. This exception is due to the difference in balance between SiO 2 and Na 2 O. With the exception of some special cases, the value of [CaCO 3 ] / [Na 2 O] is 0.2 to 1.0,
Further, it is more preferable that the system in the range of 0.4 to 0.8 shows extremely excellent strength despite the long gelation time.

Without solidification, stirring returns completely to the original suspension state at the time of mixing, even immediately after mixing,
In addition, even after several months, when the solution B, which is a sodium aluminate solution, was joined, both the gelation time and the strength were substantially within the error range. Thus, the liquid A itself is extremely stable. Further, the liquid A can further bring about the effect of maintaining the suspension state by making the particle size of calcium carbonate fine and mixing various dispersants.
