METHOD FOR PRODUCING IMPROVED SOIL
To provide a method for producing improved soil capable of making improved soil with low viscosity.SOLUTION: The method for producing improved soil has a slurry mixing step for making improved soil by mixing target soil, slurry including a cement-based hydraulic material and water. At the slurry mixing step, the target soil and the slurry are mixed using a high-pressure jet agitation method. The slurry includes a polymer that has, as a structural unit, a monomer being at least one of an ethylenically unsaturated monocarboxylic acid and an ethylenically unsaturated dicarboxylic acid; at least one of salts of the polymers; and a bicarbonate.SELECTED DRAWING: None
【課題】粘度が低い改良土を作製し得る改良土の製造方法を提供する。【解決手段】対象土と、セメント系水硬性材料及び水を含有するスラリーとを混合することにより、改良土を作製するスラリー混合工程を有する、改良土の製造方法であって、前記スラリー混合工程では、高圧噴射撹拌工法によって、前記対象土と、前記スラリーとを混合し、前記スラリーは、エチレン性不飽和モノカルボン酸、及び、エチレン性不飽和ジカルボン酸の少なくとも何れか一方のモノマーを構成単位に有する重合体、並びに、該重合体の塩の少なくとも何れか一方と、重炭酸塩とを含有する、改良土の製造方法である。【選択図】なし
