For corrosion to occur, four elements must be present: There must be at least two metals (or two locations on a single metal) at dif-ferent energy levels, an electrolyte, and a metallic connection. In reinforced concrete ...

This paper investigates the failure processes of recycled aggregate concrete by a model test and numerical simulations. A micromechanical numerical modeling approach to simulate the progressive cracking behavior of the modeled recycled aggregate concrete, considering its actual meso-structures, is established based on the discrete element method (DEM).
