A meso-scale numerical model for simulating damage in concrete due to ASR is presented. It accounts for the internal structure of concrete including aggregates and mortar. ASR sites are explicitly represented. This model is extended to account for viscoela ...
In this study, we investigate the mechanical behavior of large concrete structures affected by the alkali-silica reaction. Particularly, concrete dams are explored. Their permanent contact with water, and thus increased humidity, promotes the ASR. Seasonal ...
Alkali-silica reaction (ASR) is a concrete disease that leads to its degradation. ASR is the reaction between the amorphous silica (SiO2 ) and the alkali ions (Na + , K + ), leading to expansion of concrete in presence of Ca 2+ . In this study, it is assum ...
