CEMENT SLURRY AND GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a cement slurry utilizing seawater that can, even when applied to ground improvement method, increase the uniaxial compressive strength of the improved ground.SOLUTION: Provided are: a cement slurry obtained by adding, to a cement slurry comprising cement and seawater, a gypsum, or among others, a dihydrate gypsum, and thereby a Friedel salt and an ettringite are abundantly formed, and the uniaxial compressive strength of the improved ground can be increased; and a ground improvement method using the cement slurry.SELECTED DRAWING: None
【課題】地盤改良方法に適用した場合にも、地盤改良体の一軸圧縮強度を増加させることのできる海水を利用するセメントスラリーの提供。【解決手段】セメント及び海水を含むセメントスラリーに対して、石膏のなかでも二水石膏を添加することで、フリーデル氏塩およびエトリンガイトが豊富に生成されるため、地盤改良体の一軸圧縮強度を増加させることが可能となるセメントスラリーであり、前記セメントスラリーを用いる地盤改良工法。【選択図】なし
