| 摘要: |
| 进行了混杂纤维(钢纤维-改性聚丙烯纤维)混凝土力学性能及抗渗性能的试验研究.结果表明,混杂纤维可以提高混凝土的抗压强度、劈拉强度和抗折强度,但对混凝土抗渗性能影响不大.引气剂有助于提高混杂纤维混凝土的抗渗性.另外,简单分析了纤维混杂方式对混凝土力学性能和抗渗性能影响的机理. |

| 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. |
| Key words: hybrid fiber,mechanical property,impermeability,air-entraining agent |
