Abstract：The static and dynamic mechanical properties of basalt fiber-reinforced concrete(BFRC)and polyethylene fiber-reinforced concrete(PEFRC)with different fiber volume fractions were investigated.The results indicate that the static mechanical properties of PEFRC are better than those of BFRC with in the test parameter.The static mechanical properties of the corresponding fiber-reinforced concrete(FRC)are significantly improved when the volume fractions of basalt fiber(BF)and polyethylene fiber(PEF)were 0.10%and 0.20%,respectively.The dynamic compressive strength of concrete is optimized at a BF and PEF volume fraction of 0.20%,while PEFRC exhibits the best dynamic compression toughness at a PEF volume fraction of 0.15%.The dynamic viscoelastic damage constitutive models for BFRC developed based on the ZWT(Zhu-Wang-Tang)constitutive model,can accurately predict the dynamic mechanical properties of FRC under impact load.
