    ADDITIVE FOR SOIL IMPROVEMENT CEMENT COMPOSITION, SOIL IMPROVEMENT CEMENT COMPOSITION, SOIL IMPROVEMENT BODY AND SOIL IMPROVEMENT METHOD

    Neue Suche nach: YOKOYAMA YUYA

    To provide an additive for a soil improvement cement composition that can shorten the kneading time of soil cement.SOLUTION: An additive for a soil improvement cement composition contains: a copolymer (α) having a constitutional unit (a) derived from a sulfonic acid (salt) group-containing monomer (A) and a constitutional unit (b) derived from a carboxylic acid (salt) group-containing monomer (B); and a carbonate and/or bicarbonate. The total content of the carbonate and bicarbonate is 4-30 times the mass of the copolymer (α).SELECTED DRAWING: None

    【課題】 ソイルセメントの練りあがり時間を短縮することができる地盤改良セメント組成物用添加剤を提供する。【解決手段】 スルホン酸（塩）基含有単量体（Ａ）由来の構造単位（ａ）とカルボン酸（塩）基含有単量体（Ｂ）由来の構造単位（ｂ）とを有する共重合体（α）と、炭酸塩及び／又は重炭酸塩とを含み、該炭酸塩及び重炭酸塩の合計量が、該共重合体（α）の質量に対して４～３０倍であることを特徴とする地盤改良セメント組成物用添加剤。【選択図】なし
