【 摘 要 】

Alkali-Aggregate Reaction (AAR) is a major cause of chemical damage in concrete structures, especially those exposed to moisture, leading to cracking, excessive strains and stress formation. This work presents the results of a numerical study where the mechanical behaviour of AAR attained structures is simulated under the assumption of coupling between confinement stresses and the reaction.
