The Impact Damage Evolution of Steel Fiber Reinforced and Polymer Modified Concrete
Impact tests were carried out by use of a 74-mm-diameter split Hopkinson pressure bar to investigate the impact damage behaviors of plain concrete (PC), steel fiber reinforced concrete (SFRC) and steel fiber reinforced and polymer modified concrete (SFRPMC). The results show that all three kinds of materials appear strain rate strengthening effects, and SFRPMC appears a better impact resistance and energy absorbing ability than PC and SFRC. Based on the analysis of experimental results, a rate-dependent damage model is suggested to depict the dynamic behaviors of SFRC and SFRPMC, which derives the impact damage evolution of the materials. It shows that the damages in SFRPMC develop more slowly than that in SFRC.
