The deformation properties of basalt fiber reinforced concrete(BFRC) after exposure to different temperatures and subject to impact loading were investigated by using a 100mm diameter split Hopkinson pressure bar(SHPB) apparatus. The experimental results indicate that with the rise of temperature and impact velocity, the crushing degree of BFRC becomes greater and stress strain curves exhibit plasticity features. Under the same temperature, the peak strain and average strain increase with increase of average strain rate with obvious strain rate dependency. Under a fixed impact velocity, an increase in temperature results in a larger peak strain and average strain and enhances the strain rate sensitivity of peak strain, but after exposure to 200℃, the average strain of BFRC under a lower impact velocity is lower than that at room temperature. The addition of basalt fiber can efficiently improve the deformation performance of BFRC after exposure to elevated temperatures, and the impact deformation capability of BFRC is the best with 03% basalt fiber(volume fraction), but under lower temperature and impact velocity, the average strain of BFRC is lower than that of plain concrete.
