Multiscale Modeling of Alkali Silica Reaction Induced Damage in Concrete: Coupled Hydro-Chemical and Thermo-Mechanical Effects

Multiscale Modeling of Alkali Silica Reaction Induced Damage in Concrete: Coupled Hydro-Chemical and Thermo-Mechanical Effects

Wu, T.; Temizer, I.; Wriggers, P.

Full Article:

In this work, a 3D multiscale investigation on hydro-chemical-thermo-mechanical induced damage in concrete resulting from alkali silica reaction (ASR) is presented. 3D micro- CT scan of hardened cement paste and aggregates with a random distribution embedded in a homogenized cement paste matrix are applied to represent the microscale and mesoscale of concrete respectively. Homogenization approach is utilized to link microscale damage due to ASR and observable deterioration at the macroscale of concrete. A 3D hydro-chemicalthermo- mechanical model based on staggered method is developed.
