本発明は地盤改良剤として地盤に注入されたり基礎構造

液組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cement suspension composition that is injected into the ground as a soil conditioner or cast into formwork as a substructure material.

きくなるうえに環境が汚染されるという問題も生ずる。[Background of the Invention] Cement suspension iα, in which cement is suspended in water, has conventionally been used as this type of ground improvement agent and basic structure material. However, the cement suspension has a slow setting and hardening speed;
Since it takes several hours to set and harden, the cement in the cement suspension settles and separates before setting and hardening. As a result, the cement suspension becomes non-uniform, and only a portion of the injected cement suspension solidifies and hardens, but complete solidification does not occur as a whole. A portion of the cement suspension escapes from the target ground before setting and hardening, causing problems such as increased material loss and environmental pollution.
［従来の技術］
このようなセメント懸濁液の問題点を解消するために従

There are those that add gypsum, lime, etc., and those that add alkali metal aluminate salts to the cement suspension.

。[Problems to be solved by the invention] However, when water glass is used in combination, the strength and durability of the hardened product decreases, making it particularly unsuitable as a material for foundation structures. If the setting time becomes too fast, there is a risk that the composition will harden during preparation or injection.If you use alumina cement and add additives such as potassium carbonate if desired, the setting and hardening time can be moderately shortened, but water/ The cement ratio is very high, and strength reduction or poor strength development due to the transfer of hydration products is significant, and those to which alkali metal aluminate salts are added are still insufficient in shortening the setting and hardening time.

方法ではこの点がまだ不十分であった。[Means for Solving the Problems] First, as a means for solving the above-mentioned conventional problems, the present inventors developed a solution using a solution A, in which cement and an alkaline earth metal hydroxide are suspended in water, and an alkali aluminate. We would like to provide a cement suspension composition characterized by mixing and injecting a metal salt and an alkali metal carbonate dissolved in water and liquid B. Japanese Patent Application No. 62-257741, Japanese Patent Application No. 62-257742 )b
However, when the water temperature and outside temperature are low, such as in winter, the strength of the aggregates decreases due to the mixing of the conditioning liquid, and in such cases, the aggregates may deform due to high pressure or escape from the ground during injection. The previously proposed method was still insufficient in this respect.

Solution A, in which alkali metal aluminate and alkali metal carbonate are dissolved or suspended in water.
The present invention provides a cement suspension composition characterized by being formed by mixing and injecting a cement suspension composition with a cement suspension composition.

Ａ液およびＢ液の練り置きに対する安定性が向上する。[Function] Although alkaline earth metal hydroxides do not directly react with cement, they immediately react with alkali metal aluminates and alkali metal carbonates and exhibit an extremely large effect of accelerating setting and hardening of cement. Furthermore, by coexisting an organic carboxylic acid (salt), not only can the gel time be set arbitrarily to some extent, but also the synergistic effect significantly promotes the development of strength after setting and hardening. Furthermore, by coexisting a phosphate, the stability of the A and B solutions against kneading is improved.
