    A multiscale method to analyze the deterioration due to alkali silica reaction considering the effects of temperature and relative humidity
    (International Center for Numerical Methods in Engineering, 2013) Wu, T.; Temizer I.; Wriggers P.
    This work presents a three-dimensional multiscale framework to investigate the deterioration resulting from alkali silica reaction (ASR) in the concrete. 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.
