Chemo-Damage Model for Concrete Anisotropic Expansion Caused by Alkali-Aggregate Reaction
A chemo-damage model for concrete affected by alkali-aggregate reaction (AAR) is presented. Redistributing weights, determined by the applied stresses in the concrete, are introduced to control the anisotropic expansion of the AAR-affected concrete. Accelerated tests are analyzed using the proposed model. The computed strains of the specimens are compared with the experimental measured strains. It demonstrated that the proposed model can consider the effects of applied stresses on AAR-induced expansion with reasonable accuracy.
