钢筋阻锈剂的阻锈机理及性能评价的研究进展

摘要

The main factor causing the failure of reinforced concrete structures in advance is the corrosion of steel bar.Using corrosion inhibitor is one of the main methods to prevent corrosion.The mechanism of chloride induced corrosion in marine environment and the effect mechanism of inhibitors are mainly introduced.And the evaluation methods of inhibiting performance and application situation of corrosion inhibitor are discussed.It is pointed out that synthesis of highly efficient and environment friendly mixed inhibitors is the main research directions in the future,which is of great significance to enhance the durability of reinforced concrete structures in our country.%钢筋腐蚀是引起钢筋混凝土构筑物提前失效的主要因素,应用钢筋阻锈剂是主要的防腐蚀措施之一.重点介绍了海洋环境中,氯盐的侵蚀机理和阻锈剂的作用机理;讨论了阻锈剂的性能评价方法和应用现状;指出高效且环境友好复合型阻锈剂的合成是今后研究的主要方向,这对于提高我国钢筋混凝土结构耐久性具有重要意义.
