The impact compressive properties of concrete reinforced with various volume fractions of ceramic fiber were studied using 100 mm diameter split Hopkinson pressure bar(SHPB) apparatus. H62 brass pulse shapers of 1 mm thick and different diameter were adopted to ameliorate the incident wave so as to obtain dynamic stress equilibrium and a nearly constant strain rate over most of the test duration. The tests reveal that with the volume fraction of ceramic fiber increasing, the peak stress and peak strain enhance prominently and the descending segment of stress strain curves turn steep. The addition of short ceramic fiber can significantly improve the impact compressive strength and energy absorption capacity of the concrete and the relationship between dynamic strength increase ratio and the logarithm of strain rate can be expressed by double linear approximations. When the strain rate is(74±2) s-1, the energy absorption rate of concrete reinforced by ceramic fiber of volume fraction of 0.3% is superior to plain concrete remarkably.
