| 摘要: |
| 经冻融循环的混凝土试件在3．5％NaCl溶液中浸泡试验结果表明，冻融循环使混凝土中氯离子的含量增加，扩散系数增大，氯离子扩散系数并不是常量，且随时间变化． |

| Abstract: |
| Test results of concrete specimens subjected to freeze-thaw cycles and exposed to 3.5% Nacl solutions show that the chloride concentration and the diffusion coefficient of chloride ion increase after freeze-thaw cycles, and that the diffusion coefficient of chloride ion is not constant and varies with time. |
| Key words: freeze-thaw cycles,chloride ion concentration,diffusion coefficient,concrete,indoor test |
