自锚式悬索桥混凝土主塔防腐涂装研究与应用

On study and application of anti-corrosive coating of concrete main tower at self-anchored suspension bridge

研究了酸雨对混凝土的腐蚀机理,以实际工程为背景,对悬索桥混凝土主塔防腐涂装技术从设计、施工、检测等方面进行了论述,实践证明:采用封闭漆+中间漆+面漆的涂装体系,有效抵御了酸雨的腐蚀,有重要的推广价值。

The paper researches the corrosive mechanism of the acid rain on the concrete, indicates the anti-corrosive coating technique of concrete main tower of the suspension bridge from the design, the construction and the inspection, and proves by the practice that the adoption of coating system with the sealing paint plus intermediate coat can prevent the corrosion of the acid rain, so it has important expansion value.
