In this paper, in order to investigate impact-mechanics property of basalt fiber reinforced concrete (BFRC), impact test on BFRC with four kind of volume content (0, 0.1%, 0.2, 0.3%) was carried out using 100mm-diameter split hopkinson pressure bar (SHPB) device. Obtained dynamic stress-strain curves and testing data. Testing results were analyzed. The testing results showed that BFRC has favorable impact-mechanics properties, strain rate and fiber volume content have large effects on impact-compression strength and toughness of BFRC; impact-compression strength and toughness show strain rate strengthening effect, strain rate sensitivity of impact-compression strength is stronger and the impact-compression strength and toughness are higher relatively when fiber volume content is 0.1%; there is approximate linear function relation between the dynamic strength increase factor and the strain rate logarithm, there is approximate quadratic polynomial function relation between the peak strain and the strain rate logarithm.
