Einblicke zum Rapid Chloride Migration Test – Präzision, Chloridverlauf und Chloridbinden
Insights into the Rapid Chloride Migration Test – Precision, chloride profile and chloride binding
The Rapid Chloride Migration (RCM) test is an essential test method for assessing the chloride penetration resistance of concrete and mortar. In this article, various topics of the RCM test such as precision and consistency, the chloride profile after the test and chloride binding during the test were analysed. Good repeatability data were obtained, especially for mortar samples, and the model-theoretical penetration profile of chlorides on mortar samples was confirmed. In addition, the chloride penetration front determined using μ-XRF images was compared with the regular indicator method (using silver nitrate). The methods showed good agreement. By analysing the free and total chloride concentration in conjunction with the porosity of the samples, it was possible to provide evidence of chloride binding during the RCM test. These results emphasise the reliability of the RCM test and extend the understanding of chloride migration and binding in cement-based materials.
