在深入分析国内外RPC制备实践的基础上,提出了一种基于正交设计理论的RPC配合比设计方法.该方法采用两阶段设计,第一阶段应用正交设计理论确定RPC材料的最佳基体,第二阶段通过实验优选钢纤维掺量.应用该方法采用42.5R型水泥、粉煤灰、硅灰、普通河砂、减水剂和钢纤维等材料制备出了抗折强度高达38.6 MPa的RPC材料.

A new method for preparing reactive powder concrete (RPC) was proposed based on the orthogonal theory and current preparing experience experiments. The method contains two steps, first the best matrix of PRC material should be selected by the orthogonal design theory, then the dosage of steel fiber is optimized through experiments. On basis of the method, RPC material was prepared with cement P.O 42.5R, fly ash, silica fume, river sand, super-plasticizer and steel fiber, and its flexural strength can reach 38.6 MPa.
