IRRITANT FOR RETARDING SOIL STABILIZER AND RETARDING STABILIZER CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an irritant which is excellent to give retarding soil stabilizing property and long-term strength without decreasing separation resistance and flowing property under pressure by a pump of the emulsion of a retarding soil stabilizer used for soil improvement or the like, and to provide the retarding soil slow-hardening stabilizer containing that irritant. SOLUTION: Fine particles of a cement hydrate, for example, fine particles of a hydrate obtd. from concrete sludge, a hydrate obtd. from hardened concrete and/or a hydrate obtd. by adding water to a cement for hydration reaction are used as the irritant for a the retarding soil stabilizer. Then the irritant for the retarding soil stabilizer by 1.0 to 10.0 pts.wt. is mixed 70.0 to 99.0 pts.wt. of a blast furnace slug fine powder and 0 to 20.0 pts.wt. of gypsum to prepare the retarding soil stabilizer.
