摘　　要：本研究考虑了高性能混凝土工作性能的各项影响因素,通过对C30、C50多组分混凝土配合比设计的不断优化,从混凝土抗压强度和经济角度分析,得出最优配合比设计,为工程施工奠定良好的设计基础。同时也验证C50混凝土采用P.O42.5水泥配制,不仅强度满足要求,且经济性更好。In this study, the factors influencing the working performance of high performance concrete are considered.Through the continuous optimization of the mixture ratio design of C30 and C50 multi component concrete, the optimum mix ratio design is obtained from the analysis of concrete compressive strength and economic point of view, which lays a good foundation for engineering construction. At the same time, it is verified that the C50 concrete prepared with P.O42.5 cement, not only meets the requirements of strength, but also is more economical.
