摘　　要：通过试验观察混凝土试件遭受硫酸钠侵蚀以后表面特征的变化,分析表面状态出现的原因;并观察加载试验后试件的破坏状态与未受侵蚀试件的破坏状态进行对比,分析混凝土受侵蚀后加载破坏状态的规律。并通过试验结果结合各性能指标与影响因素(时间、水灰比)之间关系,分析硫酸盐侵蚀环境下抗力退化规律。By the observers have a concrete from the surface features sulfate erosion, analyzing the surface of the state appeared; and observe the trial after loading the destruction of state and the erosion of state have conducted by contrast, the erosion of the concrete after loading a breach of laws through the experimental results analyses the performance indicators and influence the relationship between environment and sulfate erosion concrete cube resistance under the law strength.
