ADDITIVE FOR SOIL IMPROVEMENT CEMENT COMPOSITION, SOIL IMPROVEMENT CEMENT COMPOSITION, SOIL IMPROVEMENT BODY AND SOIL IMPROVEMENT METHOD
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 having a constitutional unit derived from a sulfonic acid (salt) group-containing monomer of a specific vinyl ether, propenyl ether, or butenyl ether and a constitutional unit derived from a carboxylic acid (salt) group-containing monomer; and a carbonate and/or bicarbonate. The total content of the carbonate and bicarbonate is 0.5-30 times the mass of the copolymer.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】特定のビニルエーテル、プロぺ二ルエーテル、ブテニルエーテルのスルホン酸（塩）基含有単量体由来の構造単位とカルボン酸（塩）基含有単量体由来の構造単位とを含有する共重合体と炭酸塩、及び／又は重炭酸塩とを含み、炭酸塩及び重炭酸塩の合計量が、共重合体の質量に対して、０．５～３０倍である地盤改良セメント組成物用添加剤。【選択図】なし
