Abstract

The dynamic compressive mechanical properties of a new type of fiber reinforced concrete with twisted UHMWPE fiber were experimentally studied.The C70 high strength concrete with four different fiber volume fractions （0.3%、0.5%、0.7%、1.0%）was developed,and the impact compression experiment was conducted to study the dynamic compressive mechanical behaviors of fiber concrete under 140~255 s^-1 with Φ100 mm split Hopkinson pressure bar.The experiment result shows the compressive strength,peak strain,and elastic modulus of the UHMWPE fiber concrete have significant strain rate sensitivity.The strain rate sensitivity of compressive strength of the UHMWPE fiber reinforced concrete is lower than that of the plain concrete,while the strain rate sensitivity of the elastic modulus of UHMWPE fiber reinforced concrete is higher than that of the plain concrete.The dynamic increase factor has linear relationship with logarithmic strain rate,which is influenced by the fiber volume fraction.
