摘要
文章中论述了以 Fick扩散定律为基础 ,通过氯离子在混凝土中扩散及钢筋锈蚀的数学模型 ,应用现场实测及试验资料 ,对钢筋锈蚀及混凝土开裂时间进行了计算 ,所得计算结果与实际情况吻合。
A mathematical model showing the diffusion of chlorine ions in concrete and the corrosion of reinforcement was established on the basis of Fick's diffusion law. With this model, the corrosion of concrete and the time of cracking in concrete were calculated with the field measured and test data. The calculated results tallied with the actual situation on site.
