HIGH-STRENGTH STEEL FIBER-REINFORCED MORTAR AND PRODUCTION METHOD THEREOF
To provide a high-strength fiber-reinforced mortar having an adjustable setting time and/or setting start time, a resistance to material segregation, kneadability, and an adequate fluidity, and a method for producing the same.SOLUTION: A high-strength steel fiber-reinforced mortar comprises cement, blast furnace slag fine powder, anhydrous gypsum, silica fume, water, sand, wollastonite, high-performance water reducing agent, antifoaming agent, and steel fiber. The high-performance water reducing agent contains 0.7-1.2 wt.% based on the weight sum of cement, blast furnace slag fine powder, anhydrous gypsum and silica fume, as well as 30-150 kg/m3 silica fume and 30-120 kg/m3 wollastonite.SELECTED DRAWING: Figure 1
【課題】凝結時間および／または凝結始発時間の調整が可能で、材料分離が少なく、混練可能で、かつ、適切な流動性を有する高強度繊維補強モルタルおよびその製造方法を提供する。【解決手段】この高強度鋼繊維補強モルタルは、セメントと、高炉スラグ微粉末と、無水石膏と、シリカフュームと、水と、砂と、ワラストナイトと、高性能減水剤と、消泡剤と、鋼繊維と、を含み、高性能減水剤がセメントと高炉スラグ微粉末と無水石膏とシリカフュームとの重量和に対し0.7～1.2重量％含有し、シリカフュームが30～150kg/m３含有し、ワラストナイトが30～120kg/m３含有する。【選択図】図１
