| Résumé : |
Because of considerations related to sustainable development issues, namely the decreasing of carbon dioxide emissions, the use of CEM III cement to replace CEM I is to be developed. This study shows the influence of curing and of cement types on the porous structure of mortars made up of CEM III A and C compared with CEM I and highlights a skin phenomenon having an effect on water transfer properties. The adaptation of different methods traditionally used in petrophysics and the use of an original approach based on scanned thermal conductivity measures have helped to characterise the porous network involved and its evolution. |
