建筑系统利用氯盐作为混凝土早强剂和抗冻剂已有二十多年的历史。由于掺量过多,致使钢筋混凝土中的钢筋锈蚀,甚至造成建筑物毁坏。目前有关规范规定氯盐的掺量不超过水泥重量的2％。试验表明,钢筋混凝土中的氯盐掺加量达2％时,能促进钢筋显著锈蚀。本文试图提出氯盐最佳掺量。氯盐对钢筋锈蚀的影响钢筋混凝土中的钢筋产生锈蚀,其影响因素很多,而且
The building system has been using chlorine salt as a concrete early-strength agent and antifreeze for more than 20 years. Due to the excessive amount, the steel bars in the reinforced concrete are rusted and even cause damage to the buildings. Current regulations stipulate that the amount of chlorine salt should not exceed 2% of cement weight. Tests have shown that when the amount of chlorine salt in the reinforced concrete reaches 2%, it can promote significant corrosion of the steel bar. This article attempts to propose the optimum amount of chlorine salt. The effect of chloride on the corrosion of steel bars The corrosion of steel bars in reinforced concrete has many causes.
