Micromechanics of Hydrating Cement Pastes Considering C-S-H Gel Densification
C-S-H gel densifies progressively during hydration. Consideering that the available precipitation space may be the key parameter driving gel densification, we here use NMR relaxometry data in combination with basic stoichiometric relations of hydration chemistry, in order to develop a model for the evolution of C-S-H gel density as well as the phase volume fractions of hydrating cement pastes. Then, we combine the hydration model with a multiscale microstructural representation of cement paste. Considering full anisotropy of solid C-S-H crystals, we are able to predict the experimentally determined stiffness increase during proceeding hydration.
