| 摘 要： | 硫酸盐侵蚀是混凝土耐久性研究的热点之一.结构混凝土在实际服役过程中,常常遭受多变的环境与荷载因素的影响,使得结构混凝土硫酸盐侵蚀机理更加复杂.总结了考虑环境因素的硫酸盐侵蚀、荷载因素的硫酸盐侵蚀以及环境与荷载因素耦合作用下硫酸盐侵蚀的研究成果,指出了其研究中存在的不足.考虑实际结构混凝土服役的情况,为今后的研究提出了一些建议.

| Abstract: | Sulfate erosion is one of hot topics in the study of concrete durability.Structural concrete often suffers from the influence of varying loading and environmental factors in service life, which made the mechanism of sulfate erosion complicated.The research results of sulfate erosion considering environmental factors, loading factors, environmental and loading factors simultaneously were summarized, where the pros and cons of existing research effort are reported.Some suggestions are provided considering actual structural concrete in service. |

| Keywords: | sulfate erosion drying-wetting cycle freezing-thawing cycle flexural loading carbonization, |
