| Abstract: | Cube strength test and axis compression test of reactive powder concrete(RPC) in different steel fiber content and curing conditions were carried out on rigid compression-testing machine controlled by electro hydraulic servo valve.The cube strength was tested to define the strength grade of RPC.By testing the stress-strain curve of prism specimen,the axis compression strength was obtained and the varying regularity of stress-strain of RPC in axis compression was held.At the meantime,by comparing different s... |
