摘要
PROBLEM TO BE SOLVED: To provide an admixture for a ground improvement material in which gypsum is mixed with hydrogarnet obtained by mixing aluminum dross, a calcareous material and water and then thermally reacting them, and to provide a ground improvement material where the admixture is added to a calcareous material and/or a hydraulic material.;SOLUTION: This ground improvement material where the admixture composed of hydrogarnet and gypsum is added can be applied under a condition ranging from dry blending to wet blending, and therefore is applicable to ground improvement ranging from surface subsoil to the ground of deeper layers; moreover, since ettringite formed at that time is not affected by humic acid inhibiting the formation of cement mineral, the soil improvement material is effective to all sorts of soils ranging from the common soft ground to the leaf mold- containing-soft ground and solidified sludge.;COPYRIGHT: (C)2001,JPO
