SELF-FLOWABLE HYDRAULIC COMPOSITION, SELF-FLOWABLE MORTAR, AND MORTAR-HARDENED BODY
To provide a self-flowable hydraulic composition capable of realizing self-flowable mortars having excellent flowability, quick-hardening property, excellent shaping performance and repair performance in a wide temperature range.SOLUTION: A self-flowable hydraulic composition of this invention includes a hydraulic component consisting of alumina cement, portland cement, and gypsum, a blast furnace slag powder, fine aggregate, a fluidizing agent, and a re-emulsified resin powder. The hydraulic component contains 20-60 mass% of alumina cement, 10-50 mass% of Portland cement, and 10-50 mass% of gypsum. The self-flowable hydraulic composition further includes a calcium hydroxide powder, an iron oxide powder, and a silica fume. In this self-flowable hydraulic composition, the content of calcium hydroxide powder is 0.1-1 pts.mass, the content of iron oxide powder is 0.01-1 pts.mass, and the content of silica fume is 0.05-1 pts.mass with respect to 100 pts.mass of the above mentioned hydraulic component.SELECTED DRAWING: Figure 1
【課題】優れた流動性、高い速硬性、優れた整形・補修性を広い温度範囲において有する自己流動性モルタルを実現し得る自己流動性水硬性組成物を提供する。【解決手段】自己流動性水硬性組成物は、アルミナセメント、ポルトランドセメント及び石膏からなる水硬性成分と、高炉スラグ粉末と、細骨材と、流動化剤と、再乳化形樹脂粉末とを含む。水硬性成分は、アルミナセメントを２０質量％〜６０質量％と、ポルトランドセメントを１０質量％〜５０質量％と、石膏を１０質量％〜５０質量％とを含む。自己流動性水硬性組成物は、水酸化カルシウム粉末と、酸化鉄粉末と、シリカフュームとをさらに含む。自己流動性水硬性組成物は、水硬性成分１００質量部に対して、水酸化カルシウム粉末０．１質量部〜１質量部と、酸化鉄粉末０．０１質量部〜１質量部と、シリカフューム０．０５質量部〜１質量部とを含む。【選択図】図１
