In this contribution, 3D micro-CT scan of hardened cement paste (HCP) and aggregates with a random distribution embedded in a homogenized cement paste matrix represent the microscale and mesoscale of the concrete respectively. A 3D hydro-chemo-thermo-mechanical model based on staggered method is developed at the mesoscale of the concrete, yet taking into account the deterioration at the microscale due to ASR.EnglishAlkali silica reactionConcreteCouplingMultiscaleComputational methodsComputerized tomographyConcretesCouplingsDeteriorationSilicaAlkali-silica reactionEffects of temperatureHardened cement pasteModel-based OPCMulti-scale frameworksMultiscaleMultiscale methodRandom distributionConcrete aggregatesConference Paper
