To study the impact dynamic performance of high strength hybrid fibers reinforced light-weight aggregate concrete, this paper introduces its mixing proportion and excellent static mechanical performance first, then tests it in SHPB, obtains its failure phenomena and mechanical characteristics after being impacted one or more times, and analyzes the influence of strain rate on its mechanical performances. The results show that the hybrid fibers reinforced light-weight aggregate concrete is a kind of material highly sensitive to the strain rate, its strain rate effect is more evident than that of the common concrete, and its dynamic mechanical performance is obviously improved under high strain rate, so it is especially suitable for resisting explosion and impact action.
