%X Basic mechanical properties such as compressive strength, splitting tensile strength and flexural strength of reactive powder concrete were experimentally investigated. The influence of steel fiber volume fraction on mechanical properties of RPC was analyzed. A fitted relation expression between flexural strength and splitting tensile strength was obtained. A mathematical expression for compressive stress-strain curve of reactive powder concrete was established for different stee1 fiber volume fractions based on experimental analysis.Resu1ts show that compressive strength, splitting tensile strength and flexural strength of reactive powder concrete specimens increase along with the steel fiber content increase when the steel fiber volume fraction is in the range from 1.0% to 3.5%. When the steel fiber volume fraction is higher than 3.5%, its compressive strength decreases, the splitting tensile strength increases slightly, however, its flexural strength increases obviously.
