| Résumé : | Silanes or siloxanes have been used as post treatment water repellents for a long time. They are capable of chemically reacting with the pore surfaces thus protecting the cementitious matrix from water penetration. The study evaluates the combination of a non-ionic emulsion of a silane monomer with a silicone resin used as integral water repellent. Detailed analyses of cement hydration process were carried out by means of isothermal calorimetry, setting time measurements, and SEM investigation. It was possible to show that the hydrophobic agent introduced as integral water repellent influences the cement hydration process. Mercury porosimetry analysis showed that porosity and pore structure in cement matrix does not change due to the presence of silane emulsion. Reduction of water uptake by this emulsion was also assessed as well as its impact on the mechanical properties. |
