Abstract:This paper develops an impact bending test method and equipment compared with the ACI suggested impact test methods, and investigates the impact mechanical properties of the hybrid fiber reinforced concrete (HyFRC) with different kinds and percents of carbon fiber, steel fibers and polypropylene fiber, and analyzes the effect of the fiber type and content on the HyFRC’s impact performance. This paper suggested a hybrid factor to evaluate the quantity of the positive hybrid effect. The research results shows that the hybrid carbon fiber reinforced concrete have advanced impact resistance capacity compared with that of plain concrete.
