Abstract:

应用电化学方法测试了不同氯盐含量混凝土试件在表面涂覆迁移性阻锈剂(MCI)后不同时刻钢筋的腐蚀电流密度,应用MCI渗透模型,计算不同渗透时间钢筋界面区的阻锈剂浓度,利用统计产品与服务解决方案软件SPSS(StatisticalProductandServiceSolutions)进行多元非线性统计分析,得到了混凝土中钢筋腐蚀电流密度与界面区MCI浓度、水溶性氯离子含量的量化模型,应用该模型并根据Broomfield准则,计算出使不同氯盐含量混凝土中锈蚀钢筋腐蚀速率降低到钝化状态所需的临界MCI浓度,进而确定在混凝土表面MCI的涂覆量。采用Java语言进行计算机编程,根据混凝土强度(孔隙率)、混凝土水饱和度、水溶性氯离子含量、钢筋锈蚀程度及保护层厚度等参数,计算并输出使混凝土中锈蚀钢筋腐蚀速率降低到钝化状态所需的MCI涂覆量及涂覆工艺。
