摘　　要：研究了玻璃粉作为矿物掺合料替代部分水泥配制活性粉末混凝土(RPC)以及对其抗折性能的影响。测试和分析了玻璃粉细度、掺量以及养护温度对RPC抗折强度的影响;采用数理统计分析方法进行数值处理,得到玻璃粉细度、掺量以及不同养护温度与RPC抗折强度间的多元线性回归方程,分析3个因素的影响规律。试验结果表明,玻璃粉可作为矿物掺合料用于制备RPC,并能提高其抗折强度;当玻璃粉研磨1 h、掺量为10%、养护温度为80℃时,制得的RPC抗折强度最高。Waste glass powder was used as mineral admixture to replace some cement in the preparation of reactive powder concrete （RPC）, and its effect on flexural properties of RPC was studied in this paper. The effect of fineness and content of glass powder and curing temperature on the flexural strength of RPC was tested and analyzed：mathematical methods were used for data processing to obtain the multiple linear regression equation which showed influencing rule of fineness and content of glass powder and curing temperature on the strength. The results show that glass powder can be used as an admixture for preparing RPC and can improve its flexural strength,the flexural strength of RPC is highest when its grinding time is 1 h,its content is 10% and curing temperature is 80 ℃.
