In this paper, the confecting technique on many ingredients " hpc was studied, and the optimum ratio of many ingredients in hpc was confirmed by regression method in spss and optimizing method in matlib, considering mechanics performance of high performance concrete and collapsing slump of hpc mixture. c : bf : fa : sf : uea = 3 : 1 : 1 : 0. 2 : 0. 02. we confected out hpc with the ratio
用這一比例關系我們配製出塌落度達130mm 、早期強度高、後期強度增長幅度大的高性能混凝土，其7d 、 28d和56d的抗壓強度分別為47 . 55mpa 、 71 . 05mpa和88 . 8mpa ，後期強度增長率可達到25 。
