Abstract
The hydration processes of binders determine two principal factors that controls the ions transport during external corrosion: porosity and chemical composition (solids and pore solutions) of the cementitious system. In this study, hydration modelling is introduced to reactive transporting model, from which a self-sufficient framework for reactive transport in saturated cement-based materials from hydration to corrosion is successfully developed. The proposed model gives information on transformation of both phase assemblage and pore solutions compositions. The numerical implementation implies that the developed framework can be applied to successfully predict reactive transport in saturated cement-based materials. Furthermore, mechanism and controlling factors of sulfate attack are clarified based on simulation on sulfate ingress.
