EVALUATION OF CHLORIDE PERMEABILITY OF VARIOUS CONCRETES USING RAPID CHLORIDE PERMEABILITY TEST (AASHTO T 277-83)

This paper presents the data on the application of the Rapid Chloride Permeability Test (RCPT) to the evaluation of chloride ion penetration into concretes with and without mineral admixtures. Changes in the chloride permeability of concrete with the depth from the exposed surface were determined using RCPT. The results of RCPT showed that both surface and interior concretes with mineral admixtures were much less permeable to chloride ions than the corresponding OPC concretes. Furthermore, it was found that there were good relations between the change passed in RCPT, the initial direct current and the electrical resistivity, which also correlated well with the chloride ion penetration depth into the specimens after RCPT.
