... their mechanical properties. This paper presents a spherical diffusion–carbonation model to simulate carbon dioxide transport and its reaction with cementitious materials involved in RCAs by taking into account their typical spherical geometry – a feature frequently neglected in traditional slab-based approaches...

...Chuanqing Fu; Jia-hao Zhang; Nan-ting Yu; Wei-bin Yuan; Zhiji Gao Chloride-induced corrosion of steel reinforcement in concrete is one of the most critical durability issues in reinforced concrete structures. Chloride diffusion in concrete involves complex processes, and the diffusion coefficient...
