氯盐融雪剂腐蚀桥梁构件的机理分析及防治对策

Mechanism analysis and prevention countermeasures of chloride deicing salt corroding bridge components

通过对氯盐融雪剂腐蚀石家庄-安阳高速桥梁混凝土构件的病害调查,系统分析了氯盐中Cl-腐蚀混凝土和钢筋的机理,详细阐述了氯盐融雪剂对桥梁混凝土构件的危害,同时提出了实践中有针对性和可操作性的具体防治措施和对策,为保护桥梁构件,延长桥梁使用寿命有着积极而重要的意义。

Through the disease investigation of chloride deicing salt corroding Shijiazhuang-Anyang highway bridge concrete components,analyzed the mechanism of Cl-in chloride salt corroding concrete and steel systematically,elaborated the hazards of chloride deicing salt,and proposed targeted and operable prevention measures and countermeasures,which has a positive significance to protect the bridge components and extend the service life of the bridge.
