Abstract

Complex chemophysics of alkali-silica reaction (ASR) in Portland cement concrete deteriorates concrete service life and requires quantitative assessment. Within this context, the developed model provides a new perspective from mesoscale chemo-mechanical scheme for a better understanding of ASR kinetics. The simulated results shows how ASR expansion as well as ASR-induced damage progresses in concrete structure based on different composition of reactive aggregate and alkali hydroxide concentrations. This model can be used as an effective tool in the field of concrete materials to predict the service life, as well as on time maintenance decision of concrete structure
