THE PERMEABILITY OF CEMENT SYSTEMS TO CHLORIDE INGRESS AND RELATED TEST METHODS
This paper reviews the rapid chloride permeability test--American Association of State Highway and Transportation Officials (AASHTO) T277/American Society for Testing and Materials (ASTM) C 1202--and other chloride permeability testing methods. It also discusses the basic concepts of concrete permeability and conductivity. The paper makes an attempt at clarification and resolution of some issues. It proposes a faster and simpler alternative testing method to the AASHTO T277/ASTM C 1202 based on the alternating current impedance techniques. The new method 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.
