Abstract: In order to investigate the effect of hybrid steel fibe (SF) and polypropylene fiber (PPF) on the impact resistance of the recycled aggregate concrete (RAC), the flexural impact resistances of plain RAC, SF/RAC, PPF/RAC and SF-PPF/RAC were studied by drop weight impact test. The effects of fiber content and the way of incorporation on the impact resistance of RAC were analyzed. The mathematical statistical model was used to fit the impact experimental results and predict the failure probability. The crack resistance enhancement mechanism of SF-PPF/RAC was further analyzed. The results indicate that both single fibers and hybrid fibers can improve the impact performance of RAC. The specimen with the hybrid volume fraction of 1.5vol% SF and volume fraction of 0.9vol% PPF is found to have the maximum increase in impact energy consumption and the best ductility and toughness in concrete matrix. The impact resistance numbers of SF-PPF/RAC are well subordinated to the two-parameter Weibull distribution. The SF-PPF exhibit significant hybrid effect on improving the impact resistance of RAC.
