Abstract

Reactive powder contrete (RPC) is a high performance concrete. According to our results show that the single steel fiber when mixed with RPC, 28d highest compressive strength of RPC is 80.3MPa, flexural strength 13.45MPa, respectively, higher than the reference RPC 14.96% and 18.92%; Single polypropylene fiber when mixed with RPC, 28d highest compressive strength of RPC is 80.5MPa, flexural strength 13.5MPa, respectively higher than the reference RPC 15.25% and 19.36%; Steel fiber content is 1.5%, polypropylene fiber content is 0.7% when, RPC's 28d compressive strength up to 81.32MPa, flexural strength up to 14.37MPa, respectively higher than the reference RPC is 16.42% and 27.06%. And impact strength and resistance to splitting tear strength reached at the highest for 1.1MPa and 8.51Mpa, respectively higher 144.4% and 143.7% than the reference RPC. Two double doping greatly improved toughness and ductility of RPC, fully reflects the composite materials"Synergistic" .
