Abstract:

Many entities currently use permeability specifications in Portland cement ; concrete (PCC) pavements and structures. For those states using ; permeability specifications, two test methods are generally used and include ; ASTM C 1202 (Standard Test Method for Electrical Indication of Concrete’s ; Ability to Resist Chloride Ion Penetration) or ASTM C 642 (Standard Test ; Method for Density, Absorption, and Voids in Hardened Concrete). A couple ; of states allow the use of a surface resistivity device that correlates well with ; rapid chloride permeability results. This project will investigate the use of a ; surface resistivity device as an indication of concrete’s ability to resist ; chloride ion penetration. ; Until recently, the rapid chloride permeability test was the only test that ; quickly determined the concrete’s ability to resist chloride ion penetration. ; Recent advances in surface resistivity measurements and their correlations ; to the rapid chloride permeability results have led many owners to use them ; for a variety of reasons (i.e., low cost and a reduction in the number of man ; hours required to conduct the test).
