| 摘要: |
| 研究了高性能混凝土在盐溶液和水中的抗冻性．结果证明，高性能混凝土在盐溶液中的冻融破坏程度比水中更甚；采用在盐溶液中的冻融试验来评价高性能混凝土的抗冻性将更为严格，且该试验同时可获得冻融作用对混凝土渗透性影响的信息． |

| Abstract: |
| The frost resistances of high performance concrete in salt solution and in water were studied. It is showed that the damage of concrete in the salt solution is larger than in the water. The evaluation of the frost resistance of high performance concrete by the method of freezing-thawing cycle in salt solution is stricter than that in water. And by the test, the influence of freezing-thawing damage on concrete permeability can be determined. |
| Key words: high performance concrete,frost resistance,salt solution |
