Abstract

Several key factors such as water binder ratio, dosage of water reducing agent, sand cement ratio and volume fraction of steel fiber affecting preparation and properties of reactive powder concrete are analyzed. The test results show that water binder ratio is one of the most important factors affecting the performance of RPC. Addition of superplasticizer helps RPC achieve good fluidity with a lower water binder ratio.Adding steel fiber can greatly improve the mechanical properties of RPC,but when the steel fiber content exceeds 2% the workability is getting worse. The compressive strength decline accordingly. Appropriate curing regimes contribute to higher early strength and appropriate late strength growth of RPC specimens. The compressive and flexural strength of the optimized mixture proportion of RPC specimens can reach 166.8MPa and 32.23MPa respectively.The chloride ion penetration test shows the prepared RPC has excellent durability.
