Abstract The carbonation of concrete during service can spontaneously achieve permanent CO₂ sequestration, but its carbon sequestration efficiency is low and may cause the corrosion of steel bars. This study draws on the human respiratory system and proposes a selective internal exposure technique that can improve the carbon sequestration efficiency of concrete and avoid the corrosion of steel bars. By setting voids inside the har-dened pastes, the target area in the matrix undergoes carbonization. Moreover, the feasibility of this technology and its impact on the carbonation behavior of cement-based materials were analyzed. The results indicate that the shrinkage of superabsorbent polymer in PVC tubes can expose and carbonize the target area in the matrix, verifying the feasibility of the selective internal exposure technology. After carbonization, the amount of Ca(OH)₂ and C-S-H gel in the exposed matrix decreased, the amount of CaCO₃ increased, and the micromechanical properties of the matrix significantly improved. The addition of mineral admixtures (fly ash, granulated blast furnace slag powder, and silica fume) will consume Ca(OH)₂, resulting in a decrease in the amount of CaCO₃ generated by carbonation reaction. By regulating the depth and area of exposure, the application potential of this technology can be further enhanced.
