ANTI-WASHOUT UNDERWATER GROUT COMPOSITION, AND ANTI-WASHOUT UNDERWATER GROUT
To provide an anti-washout underwater grout composition having a long usable life, high in underwater anti-washout properties, and excellent in compression strength and split-tearing tensile strength during hardening; and to provide an anti-washout underwater grout.SOLUTION: An anti-washout underwater grout composition comprises: a cement comprising a high early strength Portland cement; a binder comprising gypsums and an amorphous aluminosilicate; a water-reducing agent; a thickener; and a fine aggregate, wherein: a content of the high-early-strength Portland cement is 42 pts.mass or more based on 100 pts.mass of the cement; a content of the water-reducing agent is 0.55-5 pts.mass based on 100 pts.mass of the binder; and a content of the fine aggregate having a grain diameter of 0.15 mm or less is 13.5-25 pts.mass based on 100 pts.mass of the fine aggregate.SELECTED DRAWING: None
【課題】可使時間が長く、水中不分離性が高く、また硬化時の圧縮強度及び割裂引張強度が優れた水中不分離グラウト組成物及び水中不分離グラウトを提供すること。【解決手段】早強ポルトランドセメントを含むセメント、石膏類及び非晶質アルミノシリケートからなる結合材と、減水剤と、増粘剤と、細骨材とを含み、早強ポルトランドセメントの含有量が、セメント１００質量部に対し、４２質量部以上であり、減水剤の含有量が、結合材１００質量部に対し、０．５５〜５質量部であり、粒径０．１５ｍｍ以下の細骨材の含有量が、細骨材１００質量部に対し、１３．５〜２５質量部である、水中不分離グラウト組成物。【選択図】なし
