Electrical Methods for Estimating the Chloride Resistance of Concrete

Michael D. A. Thomas, Professor, University of New Brunswick, Fredericton, NB, Canada Electrical methods such as surface resistivity, bulk resistivity, and electro-impedance spectroscopy are becoming more prominent to monitor concrete condition in laboratory and field applications, as illustrated through increased interest from infrastructure management agencies and the commercial availability of testing equipment sets. This session will present recent advances of such technology with potential application to nondestructive testing (NDT) and in-place structural monitoring for concrete.
