MATERIAL FOR IMPROVING GROUND, AND CONSTRUCTION METHOD FOR IMPROVING GROUND
To provide a material that allows an object ground containing a substance inhibiting a hydration reaction to have a desired strength in a stable state, while reducing the discharge of CO2 and elution of hexavalent chromium.SOLUTION: The material for improving ground is stirred with the soil of an object ground to improve the object ground. The material includes a main material mixture containing blast furnace slag and gypsum, and quick lime added to the main material mixture. The blast furnace slag content is 40 mass% or more and 80 mass% or less, the gypsum content is 5 mass% or more and 25 mass% or less, and the quick lime content is 10 mass% or more and 50 mass% or less relative to 100 mass% of the main material mixture.SELECTED DRAWING: Figure 1
【課題】ＣＯ２の排出量削減及び六価クロムの溶出量低減を図りつつ、水和反応を阻害する物質を含む対象地盤に所望の強度を安定的に発現させる。【解決手段】対象地盤の土壌に混合して攪拌し、前記対象地盤を改良する地盤改良材であって、高炉スラグ及び石膏を含有する混合主材と、該混合主材に添加される生石灰とを含み、高炉スラグは、４０質量％以上８０質量％以下、石膏は、５質量％以上２５質量％以下、生石灰は、前記混合主材１００質量％に対して１０質量％以上５０質量％以下である。【選択図】図１
