A hydraulic pressure testing machine and a 100 mm-diameter split Hopkinson pressure bar (SHPB) apparatus are used to investigate the quasi-static and dynamic mechanical properties of ceramic fiber reinforced concrete (CRFRC), which are compared to those of carbon fiber reinforced concrete (CFRC) at the same volume fractions of 0.1%, 0.2% and 0.3%. The strengthening mechanism of ceramic fiber is analyzed. The experimental results show that the ceramic fiber improves the quasi-static mechanical property of plain concrete effectively. When the volume fraction is 0.3%, the compressive strength, splitting tensile strength and flexural strength enhance by 15.0%, 8.5% and 12.7% respectively. The dynamic compressive strength and specific energy absorption of CRFRC are strain rate-dependent under impact load, and the effect can be expressed by linear approximations. The strength and toughness of CRFRC come to the best at the volume fraction of 0.2%. The strength and energy absorption properties of CRFRC are superior to those of CFRC as a whole.
