摘　　要：近年随着海洋工程和地下结构工程的发展以及结构所处环境的恶化,硫酸盐侵蚀导致混凝土性能退化和结构破坏的问题日益突出,工程质量也因此受到很大影响。所以,积极开展对硫酸盐侵蚀下混凝土的耐久性研究具有十分重要的意义,有利于提高我国混凝土工程抵抗硫酸盐侵蚀的能力。通过阅读文献并进行总结阐述了硫酸盐侵蚀混凝土的研究现状、侵蚀机理、影响因素及防治措施。In recent years, ocean environment of the structure keeps deteriorating and structure damage, engineering and underground structure projects have developed, and getting worse. Sulfate attack causes the problem of concrete performance which is becoming more and more significant. Engineering quality has also been greatly affected. Therefore, the sulfate attack of concrete damage research has an important practical significance. This paper describes the historical background of sulfate attack of concrete, research status, corrosion mechanism, influencing factors and its prevention and control measures.
