Hydration, mechanical performance and porosity of Portland cement pastes with functionalized nanosilica with APTES
This study reports on the microstructure of Portland cement a&d ej-123 pastes with nanosilica (NS) and amino-functionalized nanosilica (NSF).For this, NSF dispersion was prepared in a two-phase reaction system, consisting of an aqueous dispersion with dichloromethane, using 3-aminopropyltriethoxysilane (APTES):NS molar ratio 1:28.62.Cement pastes w
