The mechanical properties and deformation performance of concrete with the different content of coarse polyolefin fiber were researched by comparing with ordinary concrete and steel fiber reinforced concrete(SFRC). The results show that the flexural toughness, impact resistance and resistance to abrasion of concrete can be improved when mixing with a certain amount of coarse polyolefin fiber. The results are even better than that of SFRC with the same volume fraction. But the compressive strength, the flexu...
