This thesis presents a reliable multiscale multiphysics model to analyze failure induced by alkali-silica reaction (ASR) as well as by weak properties of interfacial transition zone (ITZ) in concrete. The mesostructure of concrete consists of aggregates with random distribution embedded in a homogenized hardened cement paste (HCP) as well as the interface elements with zero-thickness as a representation of the ITZ. One scale lower, the microstructure of concrete is represented by the microstructure of HCP obtained from three-dimensional computer-tomography scans, including hydration products, unhydrated residual clinker and micropores.
