摘　　要：钢筋锈蚀是造成混凝土结构耐久性退化的主要因素,而氯离子侵蚀和碳化作用则是混凝土中钢筋锈蚀的主要诱因。钢筋阻锈剂是一种能阻碍或减缓钢筋锈蚀的化学物质,其种类繁杂,效果参差不一。其中迁移型阻锈剂因其经济性、实用性以及易操作性受到业界的重视。重点综述了氯盐侵蚀和碳化作用下迁移型阻锈剂阻锈性能的国内外研究现状,便于研究人员和工程技术人员在种类繁杂的阻锈剂中挑选合适的阻锈剂及制定试验应用方法,从而进一步推动迁移型阻锈剂在实际工程中的应用。The most important factor causing durability damage of concrete structures is the corrosion of reinforcement in concrete.The corrosion may occur due to two main causes:carbonation and chloride erosion.Inhibitors are chemical substances which can prevent or slow corrosion of the steel in concretes,and the types are complicated and the effects are mixed.The use of migrating corrosion inhibitors is particularly attractive due to the simplicity and relatively low cost.The recent progress in research of migrating corrosion inhibitors under the action of chloride salt erosion and carbonization in domestic and overseas was mainly reviewed in this paper,which would be convenient to select suitable corrosion inhibitors and application methods among various kinds of corrosion inhibitors.Furthermore,the application of migrating corrosion inhibitor in practical engineering would be promoted.
