摘要
针对海洋环境中混凝土桥梁出现的腐蚀和耐久性不足现象介绍了海洋环境中混凝土结构的劣化机理,包括硫酸盐和镁盐对混凝土的腐蚀以及氯离子诱发的钢筋锈蚀。为提高海洋环境中混凝土桥梁的抗腐蚀性能,延长结构寿命,从设计、混凝土表层防护和电化学防护角度简述了加强防护的措施。
This paper introduces the deterioration mechanism of concrete structure in the marine environment,including the corrosion of concrete by sulfate and magnesium salt and the corrosion of steel bar induced by chloride ion. In order to improve the corrosion resistance of the concrete bridge in the marine environment and extend the service life of the structure,the measures to strengthen the protection are introduced from the aspects of design,concrete surface protection and electrochemical protection.
