摘要
针对新疆某渠道混凝土板表层出现松脆的现象,根据混凝土侵蚀机理及侵蚀产物的形貌、形态,通过电镜观测和环境土壤中硫酸盐含量测定结果,判定渠道混凝土板产生破坏的原因是发生了硫酸盐侵蚀破坏。
It is a phenomenon that one of key projects＇ channel concrete board surfaces appears crunchy affecting the normal water channel capacity supply in Xinjiang. According to the erosion mechanism and products morphology of concrete, using electron microscopy observation and testing sulfate volume in the soil. The results show that the sulphate attack causes the cement concrete slab damage at west main channel, channel concrete slab becomes loose, losing strength and carrying capability.
