Abstract: In this paper, the coupled transport-reaction model is validated with the experimental results on autogenous self-healing in Portland cement paste. The parameters are studied for modelling the dissolution of cement, the diffusion of ions between the solution in the crack and in the bulk paste and the precipitation of reaction products in the crack. Simulation results for different parameters are compared with the experimental results. Discussion on the coupled transport-reaction model is presented.
