This study investigates the carbonation behavior of recycled aggregate concrete (RAC) considering the constituents of coarse aggregate (CA). Coarse natural aggregate (CNA) was replaced with coarse recycled aggregate (CRA) at 0%, 20%, 40%, 60%, 80%, and 100%. The CA constituents such as Rc, Ru, Ra, Rb, and Rg were determined according to NF EN 933–11 by manual sorting before casting. Accelerated carbonation tests were performed to evaluate carbonation depth and rate. Results indicate that the variability in CA composition significantly influences RAC carbonation behavior, with strong correlations (R² > 0.9) observed between Rc and Rb contents and the carbonation performance of RAC.
