FLUIDIZATION TREATMENT SOIL
PROBLEM TO BE SOLVED: To provide fluidization treatment soil without requiring a large-scale exclusive plant, by indicating a proper flow value, without becoming excessively strong in strength after hardening while having separation resistance performance.SOLUTION: Fluidization treatment soil in the present invention includes a separation inhibitor of a cubic meter with every 1.2-1.7 kilograms, cement of a cubic meter with every 30-150 kilograms, sand of a cubic meter with every 950-1250 kilograms and water of a cubic meter with every 500-600 kilograms. The separation inhibitor is made to include hydroxyalkyl cellulose in which viscosity in the 1% dilution ratio falls within a range of 1200-5500 milli-Pascal sec and a defoaming agent of a polyether system or silicone system of 3-15% in weight percentage.
【課題】分離抵抗性を有しながら硬化後の強度が強くなり過ぎず、適度なフロー値を示し、かつ、大規模な専用プラントを必要としない流動化処理土を提供する。【解決手段】本発明において流動化処理土は、１．２〜１．７キログラム毎立方メートルの分離防止剤と、３０〜１５０キログラム毎立方メートルのセメントと、９５０〜１２５０キログラム毎立方メートルの砂と、５００〜６００キログラム毎立方メートルの水とを含む。分離防止剤には、１％希釈率における粘性が１２００〜５５００ミリパスカル秒の範囲内にあるヒドロキシアルキルセルロースと、重量百分率が３〜１５％のポリエーテル系またはシリコン系の消泡剤とを含有させる。【選択図】なし
