摘　　要：混凝土结构表面应用迁移型钢筋阻锈剂近年来越来越多地受到工程界关注,并逐渐显露了其工程优势,但我国对迁移型阻锈剂的理论研究尚停留在初步阶段。首先介绍了钢筋阻锈剂的基本原理、作用机理及分类情况,比较讨论了迁移型阻锈剂与传统阻锈剂的性能异同;进而详细阐述了迁移型阻锈剂的基本概念、作用机理、阻锈性能、渗透性能以及对混凝土性能的影响;最后,列举出世界各国迁移型阻锈剂工程应用实例。分析表明,迁移型阻锈剂可以作为一种有效的阻锈手段应用于工程实践。More and more attentions are paid to surface-applied migrating corrosion inhibitor of RC structures, while research work which has been finished in PR China remains preliminary. Basic concepts and machanism of a series of corrosion inhibitors for steel bar in RC strucures were introduced, followed by a comparative analysis for conventional corrosion inhibitor and surface-applied migrating corrosion inhibitor （MCI）. Subsequently, the basic concept, protection machanism, protection effectiveness,penetrability and the influence of MCI on concrete properties were expatiated, as well as the MCI applications were conducted. The function of MCI had been presented in every aspect according to the analysis.
