摘要
根据Fick第二定律,推导了混凝土中氯离子扩散表观动力学,其形式上遵循抛物线规律,并由此确定了原位测量混凝土中氯离子扩散系数的方法。实验表明,原位测量结果与由自然浸泡法所得自由氯离子扩散系数以及NEL法所测结果接近。
The apparent migrating function of chloride in concrete is deduced through the 2nd Fick＇s law. It obeys the parabolic law. The chloride diffusivity in concrete is directly calculated from the apparent migrating function and the experiment shows that it is similar to the free chloride diffusivity obtained by pending and NEL methods.
