| 中文摘要: |
| 通过碳纤维透水混凝土强度试验，分析了水灰比、碳纤维体积率、孔隙率对透水混凝土抗压强度、抗折强度的影响.结果表明：混凝土抗压强度随着水灰比的增大而减小，抗折强度随着水灰比的增大先增后减，相对最优水灰比为0.25～0.30.抗压、抗折强度随着碳纤维体积率的增加先增后减，在碳纤维体积率为1.5%时达到峰值.抗压、抗折强度随着孔隙率的增大而减小，建议选择孔隙率10%～15%配制透水混凝土. |
| 英文摘要: |
| The influences of water cement ratio，carbon fiber volume ratio and porosity on compressive strength and flexural strength of pervious concrete were analyzed through strength test of carbon fiber permeable concrete.The results show that：the compressive strength of concrete decreases with the increase of water-cement ratio，and the flexural strength increases first and then decreases with the increase of water-cement ratio，and the relative optimal water-cement ratio is 0.25-0.30.The compressive and flexural strengths first increase and then decrease with the increase of the carbon fiber volume fraction，and reach a peak when the carbon fiber volume fraction is 1.5%.The compressive and flexural strengths decrease with the increase of porosity.It is recommended to select the porosity of 10%-15% to prepare the permeable concrete. |
