摘　　要：研究硅灰、超细矿粉、超细粉煤灰3种矿物微粉对水泥基胶凝材料体系性能的影响。通过单掺、双掺和三掺3种掺入方式,研究硅灰、超细矿粉、超细粉煤灰矿物微粉对水泥基胶凝材料体系胶砂流动度、胶砂强度及颗粒级配的变化规律。研究结果表明,双掺3%超细矿粉和10%超细粉煤灰,水泥基胶凝材料的性能最佳。Effect of silica ash and superfine powder, superfine fly ash three kinds of mineral powder on properties of cement based cementitious material system.The single doped, double doped with three kinds of mixing methods, the research of silica fume, ultra-fine slag and ultrafine fly ash mineral powder on cement based system of cementitious mortar flow variation, mortar strength and gradation.The results show that,when mixed with 3% slag powder and 10% ultra-fine fly ash cementitious material ,the best performance.
