In this study, concrete is modelled at meso-lavel (10-4-10cm) where aggregates, mortar and/or the interfacial transition zone (ITZ) are explicitly considered. Aggregates are generated based on a given aggregate gradation and then, those are placed randomly (uniform distribution) in the concrete domain. The remaining space of concrete domain is then filled with cement mortar. In this numerical concrete model, both cube (150mm*150mm*150mm) and cylinder (diameter 100 mm*height 200 mm) specimen are modelled, and their behavior is simulated under uniaxial compression at ambient as well as at higher temperature....
