Title: Influence of Voids on Chloride Threshold in Reinforced Concrete and Potential Methods for Increasing the Corrosion Resistance
Contact: Stephen R. Sharp
Project No.: 78961
Target Date: 06/30/2012

This project will determine the significance of voids at the concrete/steel interface on the corrosion of embedded steel while simultaneously evaluating two possible methods for reducing their influence. Both methods for mitigating corrosion focus on increasing the corrosion resistance at the concrete/steel interface. The two approaches that will be studied are (a) altering the concrete mix ingredients to reduce the formation of voids adjacent to the steel and (b) electrochemically treating the concrete to increase the alkalinity adjacent to the steel, especially in regions where voids adjacent to the steel have formed that contain water.
