Reactive powder concrete (RPC) is a new type of ultra-high performance concrete(UHPC). There are many related factors that affect the mechanical properties of RPC. This paper researches on the effect of curing temperature and steel fiber type on the material strength. The research results show that within a certain range, the strength of RPC increases with the increase of curing temperature, and the maximum strength can be obtained when the curing temperature is 90°C. In the actual project, the best curing temperature is 75 °C. And the study has shown that blending fine steel fibers can optimize its mechanical properties.
