荷载裂缝对混凝土中氯离子扩散的影响

The Influence of Load Crack on the Chloride Ion Diffusion in Concrete

本文主要研究了不同宽度的荷载裂缝对混凝土抗氯离子渗透性能的影响,通过对不同深度氯离子含量的测定,结合Fick第二定律,得出了荷载裂缝对混凝土内氯离子浓度分布以及荷载裂缝对氯离子扩散系数的影响。

This article mainly explores the different widths of load crack influence on the chloride ion penetration effects in concrete. The author bases on the measurement of dif erent de-pths of the chloride ion content, combines with Fick’s second law, and draw a conclusion of load crack influence on the distr-ibution of chloride concentration in the cracks of the concrete and the chloride ion diffusion coefficient.
