ORGANIC POLYMER GROUT, AND METHODS FOR IMPROVING GROUND, FOR STOPPING UNDERGROUND WATER OF SEWAGE PIPE, AND FOR SEALING HARMFUL SUBSTANCE BY USING THE SAME

Document Type and Number:

Japanese Patent JP3741519

Kind Code:

B

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 a water soln. contg. a prepolymer having an active silanol group and a specified mol.wt. as the major component with a water soln. of a specific inorg. compd. selected from among. Ca compds., etc., as the curative component, each in a specified amt.
SOLUTION: This grout is prepd. by mixing 100 pts.vol. major component with 1-500 pts.vol. curative component. 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 (e.g. a polyether polyol chain) excluding the terminal group has a wt. average mol.wt. of 400-50,000. The curative component is a water soln. contg. 0.1-80 wt.% inorg. curative comprising a (hydro)oxide and/or a chloride contg. at least one element selected from among Ca, Mg, and Al. In the formula, R1 is H, Cl, or a 1-3C alkyl; X is O-.Na+, O-.K+, or O-.Li+; and (n) is 0 or 1.
