The Alkali-Silica Reaction (ASR) causes expansion and cracking in concrete. This can result in structural problems in concrete infrastructure that can limit the infrastructure’s service life and also generate high maintenance costs. CSHub research seeks to better understand the reaction and its mechanisms, which is key to determining solutions that will prolong the life of concrete infrastructure.
