To produce fluidized soil by preparing regulated slurry with high quality with the use of reclaimed impalpable powder.
The fluidized soil is obtained by mixing generated soil with the regulated slurry at a predetermined mixing ratio. The regulated slurry is prepared by blending water with the reclaimed impalpable powder which is obtained by heating and grinding discarded concrete so that a water quantity (W) relative to a quantity of the reclaimed impalpable powder (B) satisfies the formula of 70%<W/B<120%. Thus, the fluidized soil can be economically produced, and a fluidization method can be efficiently implemented. Further, the impalpable powder which is a reclaimed material is used as a value, and therefore the cycle of a concrete resource circulating system can be positively implemented.
