SOIL IMPROVEMENT MATERIAL AND SOIL IMPROVEMENT METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a soil improvement material for not only improving workability by fluidization of slime, but also reducing hexavalent chromium elution amount, a manufacturing method therefor and a soil improvement method.SOLUTION: There are provided a soil improvement material which is a mixture of lime sulfur mixture and cement, the lime sulfur mixture being a solution having pH of 10 or more, oxidation reduction potential (ORP) of -450 mv or less and MgO content of 0.3 mass% or more, contains further gypsum, uses the lime sulfur mixture of 0.01 to 10 pts.mass based on 100 pts.mass of cement, and a soil improvement method for reducing viscosity by mixing the soil improvement material with soil.SELECTED DRAWING: None
【課題】スライムの流動化によって施工性が改善するだけでなく、六価クロム溶出量が低減する地盤改良材料、及びその製造方法並びに地盤改良工法を提供する。【解決手段】ｐＨ１０以上、酸化還元電位（ＯＲＰ）が−４５０ｍｖ以下、ＭｇＯ含有量が０．３質量％以上の溶液である石灰硫黄合剤とセメントの混合物である地盤改良材であり、さらに石膏を含有してなる地盤改良材であり、セメント１００質量部に対して石灰硫黄合剤を０.０１〜１０質量部使用してなる前記の地盤改良材であり、前記の地盤改良材を土と混合して、粘性を低下させる地盤改良工法である。【選択図】 なし
