摘　　要：察尔汗盐湖是以氯盐为主 ,同时含硫酸盐的干涸盐湖 ,对水泥混凝土有严重的侵蚀作用。其侵蚀性质分不同部位而异 :在卤水中发生石膏型强硫酸盐化学结晶侵蚀 ;在地面以上 3 0cm以内和干燥的盐渍土部位发生复合侵蚀 ,以氯盐结晶产生的物理膨胀侵蚀为主导侵蚀方式 ,同时也存在石膏型强硫酸盐化学结晶侵蚀 ;Ca Er Han Salt lake is a dried up salt lake in the west of Qinghai province.It is a chloride lake and contains sulphate,which harmly corrods the concrete.In bittern,the concrete is corroded by sulphate;near ground and in 30cm above ground,the concrete is corroded by sulphate and mechanical damage resulting from chloride crystal.The latter is one of the chief factors that cause to corrosion .The bar in reinforced concrete is seriously corroded by chloride.altlake　CaErHansa
