Dynamic compressive properties of basalt fibre reinforced foam concrete (BFFC) under different strain rates (from 0 to 2000/s) were investigated. Series of experiments were conducted on BFFC (900, 1100 and 1300 kg/m 3 ) with 0.2% volume fraction fibre content respectively. Split Hopkinson pressure bar (SHPB) system was utilized to measure the dynamic response of BFFC. Mechanical properties including stress strain characteristics, strain rate sensitivity and peak strength of BFFC were discussed. The results show that BFFC reveal strain-hardening phenomenon and strain rate sensitivity under high strain rates, the peak compressive strength was significantly improved with the increase of density.
