本文介绍了一种新的测定 Cl~-在水泥砂浆或混凝土中的扩散深度的方法.实验表明,它能简单、直观地显示出 Cl~-扩散或渗透深度,可分辨 Cl~-浓度为≥10μg/cm~2.据此可比较和评价不同材料的抗 Cl~-扩散或渗透的能力.该方法与直接测定 Cl~-扩散系数的方法有良好的相关性.
This article describes a new method for the determination of the diffusion depth of Cl~-in cement mortar or concrete. The experiment shows that it can show the Cl~- diffusion or penetration depth simply and intuitively, and the Cl~ concentration can be distinguished. 10μg/cm~2. Based on this, the ability of different materials to resist Cl~-diffusion or infiltration can be compared and evaluated. This method has a good correlation with the direct determination of Cl~-diffusion coefficient.
