To enhance uniaxial compression strength of fluidization-treated soil having a specific gravity of 1.15 to 1.43, and enhance a recycling rate.SOLUTION: Fluidization-treated soil is obtained by mixing adjusted muddy water containing water and solid particles, and a solidification material, and has a recycling rate of 97% or more. A specific gravity of the adjusted muddy water is 1.1 to 1.3, and a moisture content of the adjusted muddy water is 62-85%. The soil particles contain 50-65% of fine grain components with a grain diameter of less than 75 μm, and the solidification material contains blast furnace C kind cement in the uniaxial compression strength at a material age of 28 days of 200 kN/m2 or more.SELECTED DRAWING: None
【課題】比重１．１５～１．４３の流動化処理土の一軸圧縮強度を高めること、リサイクル率を高めることを課題とする。【解決手段】水と土粒子とを含む調整泥水と、固化材とを混合した流動化処理土であり、そのリサイクル率が９７％以上である。前記調整泥水の比重が１.１～１.３であり、前記調整泥水の含水率が６２～８５％である。前記土粒子は、７５μｍ未満の粒径の細粒分を５０～６５％含み、前記固化材は、材齢２８日の一軸圧縮強度が２００ｋN/ｍ2以上となる量の前記高炉Ｃ種セメントを含有する。【選択図】なし
