In this contribution, the model of concrete deterioration due to alkali silica reaction(ASR) at the microscale is set up. Based on a three‐dimensional micro computer‐tomography, a finite‐element mesh is constructed at the micrometer length scale and 3D coupled Chemo‐Themo‐Mechanics model in hardened cement paste(HCP) accounting for diffusion, heat transport, micro‐crack is developed with staggering method.
