污水处理构筑物混凝土结构的腐蚀与防护综述

The Summary of Corrosion and Protection on Concrete Structure of Sewage Treatment Structure

城市污水处理厂的钢筋混凝土构筑物在受到腐蚀作用时结构性能将大大劣化,导致结构强度过早下降,构筑物达不到预期的使用年限而发生破坏。基于此,简要介绍了污水处理混凝土构筑物的腐蚀形式与不同位置腐蚀特点,阐述国内在混凝土腐蚀对策方面的研究成果,并对污水处理构筑物钢筋混凝土结构的耐腐蚀研究与发展现状进行总结与展望。

When the reinforced concrete structure of urban sewage treatment plant was corroded,its structural performance would be greatly deteriorated,resulting in the premature decline of structural strength and the failure of the structure before reaching the expected service life.Based on this,this paper briefly introduces the corrosion forms and corrosion characteristics of different positions of concrete structures for sewage treatment.It expounds the research achievements in concrete corrosion countermeasures in China,and summarizes and prospects the current research and development status of corrosion resistance of reinforced concrete structures for sewage treatment structure.
