硫酸盐腐蚀是影响混凝土耐久性重要因素之一，其劣化机理也是最为复杂的。在实际服役过程中，混凝土承受着各种复杂环境，因此混凝土的破坏多为硫酸盐与多种环境因素共同作用的结果。总结了近年来硫酸盐与应力、氯离子、干湿循环、冻融循环、碳化以及不同阳离子类型等环境单因素及多因素耦合作用下混凝土耐久性的研究成果，并且对多因素耦合作用下混凝土抗硫酸盐耐久性的研究进行了展望。

Sulfate attack is an important concern in concrete durability,and the degeneration mechanism is the most complex. Concrete exposed to a variety of complex environments in practical applications ,therefore,the damage of concrete is coursed by combined action of sulfate attack and environment multiple factors. Generalized the present research of concrete durability by environment single factor and multi-factor such as sulfate with stress,chloride ion,wet and dry cycles,freeze-thaw cycles,carbonation and type of cation. Prospects of concrete durability under environment multi-factor coupling action were also presented.
