Abstract

Concrete electrical resistivity has been verified as one of the most significant indicators in the evaluation of steel corrosion in concrete. It is also a most effective parameter in the design and operation of cathodic protection for reinforced concrete structure. In this study, an effort had been made to develop a mathematical model based on Archie’s law to characterize the coupled effects of water and chloride contents on the concrete electrical resistivity; then the developed model was verified by MATLAB using the experimental data from literature and our own experiment. The modelling results proved that the proposed model successfully described the concrete conditions on electrical resistivity at varied pore structure both qualitatively and quantitatively.
