Project description

This research aims to quantify the deleterious effects of alkali-silica reaction (ASR) on the behavior of concrete bridges, to examine the efficacy of composite-based repair to improve the capacity of ASR-damaged concrete members, to develop a theoretical model which can predict the performance of ASR-damaged and composite-repaired concrete members, and to propose design/practice recommendations for the implementation of the proposed composite repair method.
