| 摘 要： | 研究了不同水灰比配制的混凝土在浸泡,干湿循环,弯曲荷载及其复合作用下的硫酸盐侵蚀规律;并用XRD等微观方法对侵蚀机理进行了表征.结果表明:混凝土在单一破坏因素作用下侵蚀规律与多因素共同作用下的侵蚀规律并不相同,多因素侵蚀作用的规律能更准确地反映实际工程中的侵蚀规律.

| Abstract: | Effects of sulfate attack on different sorts of concrete in sulfate solution/under drying and wetting cycles/under flexural load or the combine of them were studied,the corrosions reason of sulfate attack were investigated by analyzing the corrosion product with XRD.Results show the corrosion mechanisms of sulfate attack due to single damage factor and multiple damage factors were not all the same,and multiple damage factors could indicate the concrete structure due to sulfate attack more exactly. |

| Keywords: | concrete sulfate attack drying wetting cycles single damage factor multiple damage factors |
