SOLIDIFICATION MATERIAL FOR GROUND IMPROVEMENT AND GROUND IMPROVEMENT METHOD
To provide a solidification material for ground improvement which is composed of fine particles such as viscous soil and cures a soft ground.SOLUTION: In a solidification material for ground improvement for curing a ground by mixed with soil containing viscous soil or sandy soil of the ground by stirring, a blast furnace slag SL obtained by adding sodium silicate NS having a molar ratio S/N of SiO2 component to Na2O component of 1.0-2.0 is formed into a solidification material M, a weight ratio SL/NS of the blast furnace slag SL to the sodium silicate NS is 5-32, and a water ratio W/P that is a weight ratio of a solid content weight P of the solidification material M to the water W is 100-140% (excluding case of weight ratio SL/NS of 5 and water ratio W/P of 100).SELECTED DRAWING: Figure 1A
【課題】粘性土のような微細粒子から構成される、軟弱地盤を硬化させる地盤改良用固化材の提供。【解決手段】地盤の粘性土又は砂質土を含む土と撹拌により混合されて該地盤を硬化するための地盤改良用固化材は、SiO2成分とNa2O成分とのモル比S/Nが1.0〜2.0の珪酸ナトリウムNSを添加した高炉スラグSLを固化材Mとし、高炉スラグSLと珪酸ナトリウムNSの重量比SL/NSが5〜32であり、固化材Mの固形分重量Pと水Wとの重量比である水比W/Pが100〜140％（重量比SL/NSが5であり、水比W/Pが100である場合を除く）である。【選択図】図１Ａ
