Abstract:
Electrical resistivity measurement can be used for performance-based evaluation of concrete as an alternative to other tests methods that provide an indication of the concrete’s ability to resist chloride ion penetration. Several techniques have been developed and studied for measuring the electrical resistivity of concrete, including the bulk electrical resistivity and surface electrical resistivity. The adoption of these techniques into standards and guidelines however, has been rather slow. This article discusses the different approaches to measuring the electrical resistivity of concrete and reviews the correlations between the resistivity measurements and certain durability characteristics of concrete.
