摘　　要：以掺加不同的活性矿物掺合料制成的水泥基试件,讨论了矿粉A掺量、硅粉掺量、复掺矿粉A和硅粉对水泥基材料力学性能的影响.结果表明:活性矿物掺合料对水泥基试件的抗折和抗压强度有较大影响,尤其是硅粉能够很好地提高试件的抗折强度和抗压强度.By using cement-based material inside different reactive mineral composite additive, the effect of several factors on the mechanical properties of cement-based material was studied, the factors include： the volume percentage of mineral powder A, the volume percentage of silica fume and mineral powder A blend with silica fume. The results show that reactive mineral composite additive infect the flexural strength and compressive strength of cement-based material, especially silica fume can improve the flexural strength and compressive strength of cement-based material better.

关 键 词：掺合料 抗折强度 抗压强度
