In order to study impact mechanical properties of the basalt fiber reinforced concrete, the BFRC specimens with 0、0.1% and 0.3% fibre volume content were prepared. The Φ100mm split hopkinson pressure bar apparatus was adopted tocarry out the impact compressive experiment. The dynamic stress-strain curves were obtained. The impact mechanics performance of BFRC were studied through analyzing the impact compressure strength and deformation.
