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
用这一比例关系我们配制出塌落度达130mm 、早期强度高、后期强度增长幅度大的高性能混凝土，其7d 、 28d和56d的抗压强度分别为47 . 55mpa 、 71 . 05mpa和88 . 8mpa ，后期强度增长率可达到25 。
