| 中文摘要: |
| 针对混凝土工程的耐久性研究,考察了混凝土在4种浓度盐溶液中腐蚀的情况.采用对比试验的方式,将不同水灰比的普通混凝土在不同浓度盐溶液中的损伤变化进行比较,分析了混凝土的损伤情况,水灰比越大,盐溶液的浓度越高,混凝土的损伤变化越快,这对实际工程维护有一定的参考价值. |
| 英文摘要: |
| In order to study the durability of concrete building,four concentrations were set to explore the corrosion of concrete in sodium sulphate solution.The damage mechanism of concrete durability was analyzed.The experimental results show that the concrete having high water cement ratio and immersing in high concentration sodium sulphate solution has a quick damage speed.It has reference value for engineering maintenance. |
