| 摘 要： | 通过实验室干湿循环加速硫酸盐对混凝土的腐蚀,对受腐蚀混凝土试件的抗压强度、混凝土与钢筋的粘结性能进行了测试.实验表明,SO42-与Mg2 的双重作用加速了混凝土的腐蚀,同时混凝土受硫酸盐腐蚀后脆性增大,延性及与钢筋的粘结性能均降低.

| Abstract: | In carrying out laboratory dry and wet cyclic accelerating sulfate erosion of concrete,tests are made to check the compressive strength of samples of eroded concrete and the bonding capability of reinforcing bar and concrete.The results of experiments show that,the combined effect of SO42-and Mg2 has accelerated the erosion of concrete.What's more,the brittleness of the attacked concrete by sulfate has increased,while the ductility of concrete and the bonding capability of reinforcing bar have decreased. |
