HIGH-STRENGTH MORTAR COMPOSITION
PROBLEM TO BE SOLVED: To provide a high-strength mortar composition which is excellent in workability and can exert high compression strength early only by ordinary-temperature curing.SOLUTION: A high-strength mortar composition comprises cement, silica fume, water, a water-reducing agent, an antifoam agent, fine aggregate and an inorganic fine powder. The cement contains 40.0-75.0 mass% of CS and less than 2.7 mass% of CA and has a residue on 45 μm sieve of less than 25.0 mass%. The mixture of the fine aggregate and the inorganic fine powder contains 40-80 mass% of a grain group of grain sizes of 0.15 mm or smaller and 30-80 mass% of a grain group of grain sizes of 0.075 mm or smaller, and the inorganic fine powder consists of one or more fine powders selected from limestone powder, silica powder and crushed stone powder.
【課題】施工性に優れ、かつ、常温養生のみで早期に高い圧縮強度を発現できる高強度モルタル組成物を提供すること。【解決手段】本発明は、セメントと、シリカフュームと、水と、減水剤と、消泡剤と、細骨材と、無機質微粉末とを含み、セメントは、Ｃ３Ｓを４０．０〜７５．０質量％及びＣ３Ａを２．７質量％未満含有し、かつ、４５μｍふるい残分が２５．０質量％未満であり、細骨材と無機質微粉末との混合物は、粒径０．１５ｍｍ以下の粒群を４０〜８０質量％、かつ、粒径０．０７５ｍｍ以下の粒群を３０〜８０質量％含有し、無機質微粉末が、石灰石粉、珪石粉及び砕石粉からなる群より選ばれる１種以上の微粉末である高強度モルタル組成物に関する。【選択図】なし
