| 摘 要： | 进行了混凝土在 3 5 %盐溶液中快速冻融的试验研究 ,结果表明 ,混凝土在盐溶液中冻融时重量损失大幅度增加 ,而相对动弹性模量下降略为缓慢。根据试验结果 ,混凝土的耐久性系数应该考虑相对动弹性模量和重量损失两个指标 |
| 关 键 词： | 抗冻性 冻融循环 混凝土 耐久性 除冰盐 |

| Abstract: | The frost resistance of concrete immersed in 3^5% sodium chloride solution was investigated. Compared to freezing and thawing in fresh water, the weight loss increased significantly when freezing and thawing in NaCl solution. The decrease of relative dynamic modulus of elasticity exhibited a slight slow in solution. According to the experimental results, both the weight loss and relative dynamic modulus of elasticity should be considered when determining the durability factor of concrete. |
| Keywords: | frost resistance freeze|thaw cycles concrete durability deicing salt |
