| 摘 要： | 采用在水中和硫酸盐溶液中立浸并进行干湿循环的试验方法，分析讨论了水胶比、引气剂掺量、粉煤灰掺量及轻集料对轻集料混凝土抗硫酸盐侵蚀性能影响的规律。试验结果表明：水胶比的降低可延缓硫酸盐腐蚀；掺入粉煤灰及引气剂均不同程度地提高了混凝土的抗硫酸盐侵蚀性能；与普通混凝土比，轻集料混凝土具有更好的抗硫酸盐侵蚀性。

| Abstract: | By using drying and wetting cycles in water and sulfate solution,the effects of several factors on the resistance to sulfate attack of lightweight aggregate concrete were studied,the factors include:water binder ratio,air-entrained agent,content of fly ash and lightweight aggregate.The results show that the decrease of water-binder ratio,increase of addition of air-entrained agent,addition of fly ash all improve the resistance to sulfate attack of lightweight concrete in different extent.Lightweight aggregate concrete has better resistance to sulfate attack than concrete. |

| Keywords: | lightweight aggregate concrete sulfate attack fly ash drying and wetting cycles water binder ratio air-entrained agent |
