Document Type and Number:
Japanese Patent JP3741520
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a grout which has a high penetrating, injectable, and solidifying properties, can long retain a stable strengths after solidification, and is excellent in durability by mixing an alkaline water soln. contg. a prepolymer having a specific active silanol group and a specified mol.wt. as the major component with a specified amt. of a liq. curative contg. at least one compd. selected from among., inorg. acids, etc. SOLUTION: This grout is prepd. by mixing a major component with a curative. The major component is a water soln. contg. 1-75 wt.% at least one prepolymer which has at least 0.7 terminal active silanol group of the formula per molecule and of which the main org. polymer chain excluding the terminal group has a wt. average mol.wt. of 400-50,000. The curative is a liq. (or a water soln.) contg. at least one compd. selected from among inorg. acids (or alkali metal salts thereof), water-soluble org. acids, and org. monomers slowly releasing acids in water and is used in an amt. corresponding to 30-200 mol.% of the total alkali content of the major component. In the formula, R<1> is H, Cl, etc.; X is O<-> .Na<+> , O<-> .K<+> , etc.; and (n) is 0 or 1.
