HIGH FLUIDITY RETENTION TYPE UNDERWATER NON-SEPARABLE GROUT COMPOSITION
PROBLEM TO BE SOLVED: To provide an underwater non-separable grout composition retaining fillable high fluidity for several hours or more and excellent underwater non-separability.SOLUTION: There is provided a high fluidity retention type underwater non-separable grout position containing a binding material containing cement and pozzolan, an aggregate, a polycarboxylic acid-based cement dispersant, and a thickener with the cement of 60 to 85 pts.mass and fly ash of 15 to 30 pts.mass based on 100 pts.mass of the binding material, the polycarboxylic acid-based cement dispersant of 0.5 to 3.5 pts.mass and the thickener of 0.6 to 3.0 pts.mass based on 100 pts.mass of the cement.SELECTED DRAWING: None
【課題】充填可能な高い流動性を数時間以上保持し、かつ優れた水中不分離性を有する水中不分離性グラウト組成物を提供すること。【解決手段】セメント及びポゾランを含む結合材と、骨材と、ポリカルボン酸系セメント分散剤と、増粘剤とを含有し、結合材１００質量部に対しセメントを６０〜８５質量部、フライアッシュを１５〜３０質量部含有し、セメント１００質量部に対しポリカルボン酸系セメント分散剤を０．５〜３．５質量部、増粘剤を０．６〜３．０質量部含有することを特徴とする高流動保持型水中不分離性グラウト組成物。【選択図】なし
