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)的可行性。研究了玻璃粉掺量、细度以及养护温度对RPC强度的影响;采用数理统计分析方法进行数值处理,求得玻璃粉掺量、细度以及不同养护温度与RPC强度间的多元线性回归方程,分析三个因素的影响规律。试验结果表明:玻璃粉可作为掺合料加入RPC中并提高其强度;当玻璃粉掺量为10%、研磨1h、养护温度为80℃时试件的抗压强度最佳。The feasibility of glass powder working as mineral admixtures to replace part of cement in preparation of reactive powder concrete（ RPC for short） is studied in this paper. The effect of the fitness of glass powder,glass powder dosage,and curing temperature on the compressive strength of RPC is analyzed. Mathematical methods are used for data processing to obtain the multiple linear regression equation which shows influencing rule of content,and fineness of glass powder and curing temperature on RPC strength. The results show that the glass powder can be added as an admixture in RPC to improve its compressive strength,and the strength of the specimens is highest when the glass powder content is10%,grinding time is 1h and curing temperature is 80℃.
