Abstract
Coupled reactive-transport processes in cementitious materials play a crucial role in the aging process pf building materials. Up to now, the effect of aging on microstructure and evolution of it’s properties, in three dimensions, was studied only by dissolution of certain phases at random locations. In this paper we present a new 3D reactive-transport model and results of leaching-induced aging simulations performed on virtual cementitious microstructures generated by Hymostruc model. The outputs are the morphology of the aged 3D microstructure together with aged properties characterised by fuzzy state of each voxel at different times. This allows to simulate the evolution of properties as a function of time as well as a function of the location within the microstructure.
