Abstract High-speed impact compression tests of reactive powder concrete (RPC) with 0%, 0.5%, 1% and 1.5% volume fraction of basalt fiber (BF) were carried out by using the 50 mm split Hopkinson pressure bar (SHPB). The effects of BF volume fraction and strain rate on the dynamic compressive strength, ultimate strain, impact toughness and failure degree of RPC were studied. A dynamic constitutive equation for basalt fiber reactive powder concrete (BF-RPC) considering damage was established. The results show that RPC has significant strain rate effect, and for RPC with the same volume fraction of BF, the dynamic compressive strength, dynamic strength growth factor, ultimate strain, impact toughness and crushing degree increase gradually when the loading strain rate increases from 60 s^-1 to 120 s^-1. The impact mechanical properties and failure morphology of RPC are changed by the addition of BF. When the volume fraction of BF with the same loading strain rate increases from 0% to 1.5%, the dynamic compressive strength and impact toughness of RPC first increase and then decrease with the increase of BF volume fraction, and the generation and propagation of cracks can be effectively restrained by the addition of BF. Overall, the optimal volume fraction of BF is 0.5%. By fitting the experimental stress-strain curves, it is known that the dynamic constitutive model considering damage is suitable for BF-RPC.
