Reactive powder concrete (RPC) is a new type of high performance concrete (HPC) which due to using fine powder and pozzolanic materials as well as high amount of materials which are hydraulically active, is known as this name. RPC characteristics have a high sensitivity to type and characteristics of materials used in RPC; therefore, in order to achieve desired physical and mechanical properties, it is necessary to carefully consider selection of materials and mix proportions. The purpose of this research was to investigate the effect of water to ementitious materials ratio (W/CM), amount of cementitious materials (CM), silica fume to cementitious materials ratio (SF/CM), cement type and grading of silica sand on compressive strength of RPC. To do so, 21 RPC mixes were designed and made. In each step of this research, one of the effective parameters were studied and accoding to obtained results, the next steps were performed. RPC specimens were cured in 90 oC water for 7 days. Results showed that by using cement type V, cementitious materials of 1100 kg/m3, water to cementitious materials ratio equal to 0.2, silica fume to cementitious materials ratio equal to 0.2 and use of silica sand with the the finest grading, the highest compressive strength can be achieved.
