摘要

PROBLEM TO BE SOLVED: To obtain a soil solidifying material capable of providing improved soil good in fluidity or early strength developing properties by mixing excavated soil, etc., together with water when excavating the ground and installing a pile or a pole, etc., and enabling works with excellent permeability into gaps without producing voids in the ground. SOLUTION: This cement admixture for solidifying soil comprises calcium aluminate, an inorganic sulfate and an alkali metallic bicarbonate in an amount of 0.5-5 pts.wt. based on 100 pts.wt. sum total of the calcium alminate and inorganic sulfate. Furthermore, the material for solidifying soil comprises the cement admixture for solidifying the soil in an amount of 10-50 pts.wt. based on 100 pts.wt. sum total of a cement and the cement admixture for solidifying the soil.
