A COUPLED TRANSPORT-REACTION MODEL FOR SIMULATING AUTOGENOUS SELF-HEALING IN CEMENTITIOUS MATERIALS-PART Ⅰ: THEORY

摘要：

　　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.
