The time evolution of some microstructural parameters (porosity, composition) and physical properties (electrical conductivity) of young cement pastes have been modelled by means of a numerical code (chemhyd3d) based on the percolation theory. The computational results have been compared with experimental data (for the electrical conductivity) and porosities reckoned by the Powers equation. Very good agreement has been found which indicated that the effects of the foremost parameters on the properties of mortars and concrete can now accurately predicted.

Abstract
The time evolution of some microstructural parameters (porosity, composition) and physical properties (electrical conductivity) of young cement pastes have been modelled by means of a numerical code (chemhyd3d) based on the percolation theory. The computational results have been compared with experimental data (for the electrical conductivity) and porosities reckoned by the Powers equation. Very good agreement has been found which indicated that the effects of the foremost parameters on the properties of mortars and concrete can now accurately predicted.File in questo prodotto:
