Abstract: The high-strain-rate mechanical behavior of the basalt fiber reinforced geopolymeric concrete (BFRGC)，including compressive strength，deformation and energy absorption capacities，was investigated using a 100mm-diameter split Hopkinson pressure bar (SHPB). The experimental results show that the highst-rain-rate behavior of geopolymeric concrete materials exhibits strong strain rate dependency. The addition of short basalt fibers can significantly improve the deformation and energy absorption capacities of the geopolymeric concrete (GC)，while there is no notable improvement in the compressive strength.
