摘　　要：主要介绍了亚硝酸盐在混凝土中的钢筋阻锈机理及亚硝酸盐在混凝土中的物理力学性质。同时探讨亚硝酸盐在国内外钢筋混凝土中的研究现状和常用的应用范围 ,并针对不同环境和腐蚀特点提出相应的阻锈措施。The mechanism of corrosion inhibition and physical properties of nitrites in reinforced concrete are introduced,and the up-to-date progress and application are reviewed in this paper.In the meanwhile,corrosion inhibition approaches are presented.Finally,it is pointed out that concrete reinforcing bar can be protected if the NO 2^-/Cl^- ratio is higher than a threshold.

关 键 词：钢筋混凝土 亚硝酸盐 阻锈
