寒冷地区道路水泥构件病害机理分析

寒冷地区冬季道路积雪严重影响行车安全,为消除隐患,养护部门一般通过撒融雪剂或盐进行除冰。但是融雪剂或盐对水泥混凝土构件表面的腐蚀性很强,采取上述养护方式往往缩短了混凝土构件的使用寿命。作者通过室内低温抗冰冻、盐蚀、耐酸碱等试验和现场实施,研究了盐对混凝土构造物侵蚀的一般规律,本文介绍了水泥混凝土构件的腐蚀机理,其分析结果可为提出寒冷地区道路水泥混凝土构造物的养护方法及开发新的防腐蚀材料提供借鉴。

The mechanism analysis of the diseases of the cement component for road in cold regions

Because the driving safety in the winter of cold regions is severely affected by snow in the road,in order to eliminate hidden dangers,the maintaining departments usually use snowmelt agent or salt to remove ice.But snowmelt agent or salt is very corrosive to the surface of the cement concrete component,so taking the above maintenance way often shorten service life of the concrete member.Based on the laboratory tests at a low temperature about resistance to freeze and the corrosion of salt,acid,alkali,etc.a...
