| 要旨 |
In this study, a coupled physical and geochemical model was developed for predicting the durability of cementitious materials. DuCOM (Durability Concrete Model) and geochemical code PHREEQC were used for this purpose. The coupled model takes into consideration of hydration of cement particles, transport of multi species, and chemical interaction of ions with cement phases. The predicted pore solution composition successfully compared with reported experimental data. Further, the coupled model was applied to understand the external sulfate attack in concrete. |
