To provide a method for fluidizing a soil cement slurry which is capable of imparting enough fluidity and fluidity maintaining property to the soil cement, and, at the same time, capable of imparting enough water-stopping property, strength, and the like, to the resulting hardened soil cement, through suppressing foaming property and promoting uniform mixing of a cement milk and a soil.
The method for fluidizing a soil cement slurry comprises mixing a cement milk with a fluidizing agent comprising a component A which is a water-soluble vinyl copolymer formed by alkali-hydrolyzing a copolymer of isobutylene and maleic anhydride and has a mass-average molecular weight of 2,000-50,000, a component B which is one or more selected from the group consisting of saccharides, oxycarboxylic acids and salts of oxycarboxylic acids, a component C which is a specific aliphatic polyether, and a component D which is a specific polyether-based defoaming agent, and containing 50-95 mass% of the component A, 2-35 mass% of the component B, 0.1-20 mass% of the component C and 0.01-5 mass% of the component D, in a mixing ratio of 0.5-25 kg of the fluidizing agent per 1 m3 of soil.
