| 摘要: |
| 在论述混凝土抗渗性重要作用的基础上，分析了影响混凝土抗渗性的一些因素，提出了提高混凝土抗渗性的一些措施。最后，指出现行表征混凝土抗渗性方法存在的问题，推荐以混凝土的渗透系数（或扩散系数）来评定混凝土的抗渗性。 |

| Abstract: |
| In this paper,based on the demenstration of importance of concrete anti-permeability and analysis of some factors influenced on concrete anti-permeability,some measures for increasing anti-permeability are proposed. Fanally,the problems of expressing the method of concrete anti-permeability at present are noted and the evaluating method concrete antipermeability with the help of concrete disffusion (or permeability ) coefficients is suggested. |
