| Abstract: | Experiment on mechanical properties and impermeability of steel fiber and modified po-(lypropylene) fiber hybrid reinforced concrete were carried out.The test results show that hybrid fibers increase concrete's compressive strength,splitting tensile strength and flexural strength,but it have little effect on concrete's impermeability.And air-entraining agent increases impermeability of hybrid fiber reinforced concrete.The reason why hybrid mode of fiber has effect on mechanical properties and impermeability of hybrid fiber reinforced concrete are also analyzed. |

| Keywords: | hybrid fiber mechanical property impermeability air-entraining agent |
