摘要
综述了严酷环境下混凝土中钢筋锈蚀的研究现状,论述了钢筋在混凝土碱性环境中的钝化机理,以及碳化和氯盐作用下的钢筋锈蚀机理;讨论了表面防护、阻锈剂、电化学阴极保护和钢筋表面涂镀等钢筋腐蚀防护措施的作用机理及优缺点。
The research status of rebar corrosion in severe corrosive environment was summarized. The passivation mechanism in alkaline condition of rebar in concrete and the corrosion mechanism under the action of carbonation and chloride were expounded. The effective mechanisms and advantage and disadvantage of some regular protective measures for the rebar, including surface protective materials, inhibitor, electrochemical protection and rebar＇s coatings were discussed.
