In order to study the tenacity increase characteristics of basalt fiber reinforced concrete(BFRC)under impact loading,the dynamic stress-strain curves of BFRC with six kinds of volume content(0%,0.05%,0.1%,0.15%,0.2%,0.25%)subjected to various high strain rates was investigated using a 74-mm-diameter split Hopkinson pressure bar(SHPB)device.The effect of volume fractions and strain rate on dynamic toughness were studied according to the stress-strain curves obtained by the experiments.Meanwhile,the interfac...
