Abstract

This article reports on investigations of the resistivity and chloride migration coefficient (DRCM) obtained in the accelerated Rapid Chloride Migration test for slag cement-based concretes. Determinations of the resistivity and DRCM were performed on 47 different concrete compositions, up to the age of 182 days. The obtained results demonstrate that, within the investigated age of concrete, factors such as cement fineness, slag origin, w/c ratio and cement and effective water contents clearly influence concrete resistivity and DRCM values. Moreover, a linear trend is observed between DRCM and conductivity. Based on this trend, resistivity determination is proposed as an alternative method for more laborious and time consuming chloride ingress test methods.
