Modeling Ageing Cementitious Pore Structure
Abstract Coupled reactive-transport processes in cementitious materials play a crucial role in the ageing process of building materials. Up to now, the effect of ageing on microstructure and evolution of their properties, in three dimensions, was studied only by the dissolution of certain phases at random locations. In this paper, we present a new 3D reactive-transport model and the results of leaching-induced ageing simulations performed on virtual cementitious microstructures generated by the Hymostruc model. The outputs are the morphology of the aged-3D microstructure together with aged properties characterised by the fuzzy state of each voxel at different times. This enables simulating the evolution of properties as a function of time, as well as a function of the location within the microstructure. Correlation results obtained from pore-scale (3D) modeling should then be used to make a homogenized, predictive model to be used for the design (ageing assessment) of full-scale structures.
