Microstructure-based prediction of the elastic behaviour of hydrating cement pastes

The development of the elastic properties of a hardening cement paste results from the microstructural evolution due to cement hydration. The elastic behaviour of cement paste can be predicted by a combination of the hydration model and micromechanical analysis, which originates from a microstructural representative volume where the elastic...

Microstructure-based 3D modelling of diffusivity in sound and cracked cement paste

Exposing reinforced concrete (RC) structures to aggressive environmental conditions is one of the main reasons that may limit their service life. Diffusion of chloride ions through concrete cover is one of the most damaging environmental actions, since it may cause corrosion of steel reinforcement. Therefore, modelling this phenomenon allows...
