Abstract: In this study, a coupled transport-reaction model is developed for simulating autogenous self-healing in cementitious materials. The diffusion of ions between the solution in the crack and in the bulk paste is simulated with a transport model. The concentration of ions in the crack can be calculated. The chemical reactions taking place in the crack are simulated by a thermodynamic model. With the thermodynamic model, the amount of reaction products formed in the crack and the remaining ion concentrations after the chemical reactions can be determined. In this way, autogenous self-healing in cementitious materials is simulated iteratively.
