To study the enhancement effect of basalt fiber on concrete of different materials, basalt fiber reinforced ordinary portland cement-based concrete (BFROPCC) and basalt fiber reinforced geopolymeric concrete (BFRGC) were produced. The impact mechanical properties of BFROPCC and BFRGC were investigated using a 100-mm-diameter split Hopkinson pressure bar (SHPB). In addition, the effect of short basalt fiber fraction on the enhancement of strength and ductility for concretes with these two different types of binder materials were studied. The strength and toughness are improved with the increase of the strain rate, and the strain rate sensitivity values are 29.5 and 40.9 s-1 respectively. Compared with geopolymeric concrete (GC), the basalt fiber has better strengthening effect on ordinary portland cement-based concrete (OPCC), and the strengthening and toughening effect are relatively the best with 0.1% fiber volume content for OPCC. Basalt fiber is not proper for strengthening GC, while the toughening effect is relatively the best with 0.3% fiber volume content for GC.
