Abstract
En 中文
• A coupled Cl--SO42- transport model for concrete was developed. • Sulfate consumption and C₃A depletion were explicitly considered. • AFt-induced cracking was quantitatively linked to chloride diffusivity. • Transport, reaction, and damage evolution were modeled simultaneously. • The model was validated by chloride profiles under mixed-salt exposure.
