Alkali-Silica reaction is a form of chemical degradation of concrete that occurs in the presence of aggregates characterized by a particular mineralogical composition, causing expansion of the altered aggregate. Since this process is slow, expansion can occur during the concrete hardening phase, causing localized swelling and cracks, resulting in critical structural problem.
