Mechanical Behavior of Reactive Powder Concrete Made From Local Material Subjected to Axial Pressure

In order to investigate the influence of various parameters on compressive strength and fluidity reactive powder concrete (RPC) made from local materials, 22 groups RPC cubic specimens 3 prism were designed, main included water binder ratio, ratio silica fume cement, slag quartz sand volume fraction steel fiber, steam curing time. The stress-strain curves failure mode obtained by axial compression test. mechanical properties mixture was analyzed. results showed that ultimate ( f cu ) gradually decreases with increase in ratio; however, c u increases fiber. firstly then so there exists a peak point. cement; contrary, it Based analysis parameters, optimal mix proportion materials is proposed. constitutive model established according specimens. Finally, relationship between elastic modulus regressed statistically.
