Orthogonal Experimental Study on the Mixing Proportion of Reactive Powder Concrete

According to the principle of Preparation about Reactive powder concrete (RPC),selection of local raw materials,the use of orthogonal experimental design method,carried out research of RPC mixing proportion design. Finally get the RPC optimal mix of meeting engineering requirement. By the range analysis and variance analysis of the test data of mix,obtained the influence law about water-cement ratio,steel fiber content, sand type,curing regime on compressive strength and splitting tensile strength .
