Towards Structural Modelling of Alkali-Silica Reaction in Concrete
Structures affected by Alkali-Silica Reaction (ASR) include large massive concrete dams and bridges, which are considered essential for the infrastructure system, and not easily replaceable. The main feature of this reaction is the creation of a hydrophobic expansive gel which causes internal damage in the concrete. This damage is strongly related to the macroscopic stress state. Vice versa, the caused damage can have macroscopic consequences. Therefore a structural model should be able to capture the chemo-mechanical coupling induced by the swelling. For this purpose a multiscale material model is chosen to represent the ASR-affected concrete behaviour in structures. In this paper the motivations which brought the authors to this choice are explained.
