METHOD FOR PRODUCING HYDRAULIC SLURRY AND GROUND IMPROVEMENT METHOD
To provide a method for producing a hydraulic slurry which maintains flow stability with time of a hydraulic slurry that is a kneaded product of hydraulic powder such as cement milk and water, and can suppress viscosity increase with time when the hydraulic slurry is mixed with soil, and a ground improvement method using the hydraulic slurry obtained by the production method.SOLUTION: There are provided a method for producing a hydraulic slurry which includes mixing hydraulic powder with water to prepare a mixture, and adding (A) an admixture to the mixture, and a ground improvement method which includes mixing a hydraulic slurry obtained by the production method with soil. In the ground improvement method, the component (A) is an unsaturated carboxylic acid polymer or its salt. The ground improvement method includes adding (B) one or more compounds selected from the group consisting of an oxycarboxylic acid or its salt, sugar and sugar alcohol, to the mixture.SELECTED DRAWING: None
【課題】セメントミルクのような水硬性粉体と水の混練物である水硬性スラリーの経時的な流動安定性を維持し、且つ該水硬性スラリーを土壌と混合した際の経時的な粘度上昇を抑制することができる水硬性スラリーの製造方法及び該製造方法で得られた水硬性スラリーを用いた地盤改良方法の提供。【解決手段】水硬性粉体と水を混合して混合物を調製し、該混合物に（Ａ）混和剤を添加する水硬性スラリーの製造方法、及び当該製造方法で得られた水硬性スラリーを土壌と混合する地盤改良方法。（Ａ）成分が不飽和カルボン酸重合物又はその塩である地盤改良方法。さらに（Ｂ）オキシカルボン酸もしくはその塩、糖及び糖アルコールからなる群より選ばれる１種以上の化合物を、前記混合物に添加する地盤改良方法。【選択図】なし
