The initial microcracks of the recycled aggregate concrete (RAC) usually first appear in the interfacial transition zone (ITZ) during the destructive process. Thus, the performance of ITZ plays an important role in the mechanical properties of concrete [7,8]. In order to improve the mechanical performance, we add iron ore tailings (IOTs) to RAC.
