Abstract:
Six proprietary concrete repair systems were evaluated for their performance and durability under field conditions. The fieldwork consisted of repairing corrosion-damaged reinforced concrete barrier walls of a highway bridge, and installing embedded instrumentation for their continuous monitoring over 3 years. The results indicated that the proprietary repair systems reduced the risk of corrosion in the patches; however, the risk of corrosion in the existing concrete was not reduced. All concrete repair systems suffered from shrinkage cracking.
