- UHMWPE fiber reinforced concrete, triaxial compression experiment, stress-strain curve, strength, compression toughness.
A triaxial compression test was carried out to investigate the effect of ultra high molecular weight polyethylene (UHMWPE) on concrete’s behavior, in which four kinds of fiber volume fraction (0%, 0.3%, 0.5%, 1.0%) and five kinds of confining pressure (0MPa, 3MPa, 6MPa, 12MPa, 18MPa) were designed. The experiment result shows that both confining pressure and fiber volume fraction have influences on the stress-strain curves of the fiber reinforced concrete where the confining pressure’s improvement will increase peak stress and mixing fiber will increase limit strain. According to that, a formula is given to describe the relationship between the strength of UHMWPE fiber reinforced concrete, confining pressure and fiber volume fraction. Then by using compression toughness index method, the relationship between the toughness of UHMWPE fiber reinforced concrete, confining pressure and fiber volume fraction is also revealed. When the confining pressure is 18 MPa and the fiber volume fraction is beyond 0.5%, the toughness improvement is the most remarkable.
