| Abstract: | In this paper the mechanic properties of the concrete reinforced with the micro-steel fibers and polypropylene were studied systematically. The influence of the hybrid way on the fracture properties was studied. Based on the experiment results, the fracture ductility index Ktc and the fracture energy GF were obtained for the hybrid reinforced concrete. |
