Abstract:
Several state and federal agencies have shown interest in adopting surface resistivity (SR) measurement for quality assurance testing. But SR measurement may also be used for assessing and predicting the long-term performance of concrete mixtures during the mixture design stage. As shown in this article, the SR test demonstrates the influence of binder composition on the rate of microstructural development in concrete and can therefore provide a means for assessing future performance.
