摘要
模拟自然条件下钢筋在融雪剂中的腐蚀环境,采用干湿交替浸泡试验,用失重法测定几种不同浓度的商品融雪剂对钢筋的腐蚀速度,同时借助扫描电镜分析腐蚀产物的表面形貌,结果表明当融雪剂溶液浓度为15%~20%时,钢筋的腐蚀速度最小;而浓度为3.5%时,钢筋的腐蚀速度最大。
Corrosion velocity of steel bar in deicing salt of different concentrations was mensurated by weight-loss method in alternate immersion test which simulated the natural corrosion environment.The corrosion surface was observed with scanning electron microscopy.The corrotion rate was minimum at the concentration of deicing salt from 15% to 20% and maximum at the concentration of 3.5%.
