CEMENT-BASED SOLIDIFYING MATERIAL, AND CONDITIONING METHOD OF GROUND BY USING THE SOLIDIFYING MATERIAL

摘要

PPROBLEM TO BE SOLVED: To provide a cement-based solidifying material which solidifies sufficiently soil regardless of a kind of the soil to thereby develop high strength and suppresses the elution of hexavalent chromium from the mixed soil inside to an extremely low level. PSOLUTION: The cement-based solidifying material is obtained by firstly preparing a mixed salt by mixing calcium chloride, potassium chloride and magnesium sulfate in a weight ratio of 62:30:8 respectively, thereafter by secondly mixing the mixed salt obtained as the above of 0.625 pt.wt. relative to 100 pts.wt. of portland cement as a cement material.
