The Permeability of Cement Systems to Chloride Ingress and Related Test Methods



The rapid chloride permeability test (AASHTO T277/ASTM C 1202) and other chloride permeability testing methods are critically reviewed. The basic concepts of concrete permeability and conductivity are also discussed. An attempt at clarification and resolution of some issues is made. A faster and simpler alternative testing method to the AASHTO T277/ASTM C 1202 based on the a-c impedance techniques is proposed. It provides at least an equivalent indication of the concrete permeability with respect to AASHTO T277/ASTM C 1202 and is without several shortcomings characteristic of the current methods.
