Abstract: This paper studied the chemical corrosion effect that the acid rain would bring to the concrete pavement by using chemical reaction theory among materials. The chemical reaction equation between the acid rain and the alkali aggregate and the water-cement solid in concrete mixtures are deduced in the paper. The results indicate that the chemical reactions between the acid rain and the concrete pavement can produce salinities that are easy to dissolve in water. And also based on series tests bet

摘要: 基于物质问发生化学反应的基本规律探讨酸雨对水泥砼路面的化学破坏作用,得出了水泥砼路面材料与酸 雨中的酸性物质发生化学反应的方程式,酸雨中的酸性物质与水泥砼中的水泥凝胶材料和骨料均会发生化学反 应,且反应都会生成可溶于水的盐类,不同酸度酸雨对砼材料抗弯拉强度影响的模拟试验表明,酸雨对砼的强度有 着明显的不良影响,且酸雨的酸度越高,对水泥砼材料的强度影响越大,当酸雨的pH值小于3。0以后,砼的抗弯拉 强度减小加快,由此推论酸性较强的酸雨对水泥砼路面病害的产生具有明显的促进作用
