摘　　要：活性粉末混凝土作为一种超高性能混凝土材料,其配合比直接关系到其性能的优劣,亦是研究其性能的基础.本文首先回顾了RPC配合比设计理论基础,并对典型的RPC配合比设计方法进行了归纳和总结,分析了各方法的适用范围和特点,深入讨论了RPC配合比设计参数的适宜取值范围.目前活性粉末混凝土配合比设计主要基于试验方法、半经验半理论公式方法、编程计算方法.但是试验方法和编程计算方法无法直接进行强度预测,配合比设计具有较大不确定性.通过对典型半经验半理论公式方法进行评价分析发现法国路桥公式的准确度较高,可作为简易的强度预测公式使用,但该方法未考虑钢纤维掺量及养护制度对强度的影响.The mix proportion of the reactive powder concrete （RPC） dominates its mechanical properties. It is essentially to understand the mix design theory in order to study RPC structures deeply and widen its application. This paper firstly reviewed the mix design theory of the cement-based composites and analysed the critical parameters which had been identified affect the performance of RPC. At present, the mix proportion design of RPC is mainly based on the test method, the semi empirical and semi theoretical formula method and the programming calculation method. But the test method and programming calculation method can not directly predict the strength. Based on the analysis of typical semi empirical and semi theoretical formula, the accuracy of LCPC formula is more accurate, which can be used as a simple strength prediction formula. But the method has not considered the influence of steel fiber content and curing system on the strength.
