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).
