Abstract: There are four main factors affecting the compressive strength of reactive powder concrete:W/B(water and binder ratio), silica fume content, S/B(sand and binder ratio), steel fiber content.Based on the previous research , through the experimental analysis of the four factors on the influence of reactive powder concrete compressive strength and fluidity , and then through the orthogonal test to optimize the mix, successfully prepared RPC180 reactive powder concrete .
