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, with the development of offshore engineering and underground structural engineering and the deterioration of the environment in which the structure is located, the problem of deterioration and structural destruction of concrete caused by sulfate erosion has become increasingly prominent, and the quality of construction has also been greatly affected. Therefore, it is of great significance to study the durability of concrete under sulfate attack actively, and to improve the ability of concrete engineering in our country to resist sulfate attack. By reading the literature and summarizing the research status, erosion mechanism, influencing factors and prevention and cure measures of sulfate attack concrete are expounded.
