Abstract
This research study attempts to investigate and explain the role of nano-alumina (NA) in traditional binders, such as clay, lime, and pozzolan. Three different modified binding systems with NA, lime-pozzolan as a hydraulic system that was cured in humid conditions and clay and lime-clay systems that were cured in aerial conditions, were studied on their physico-mechanical properties and their mineralogical composition. Nano-particles of 1.5% by mass of binder were added in each system in a defined quantity of water and ultrasonication. Results indicated different behaviors of NA in each binder system, as clay was the most favored system, while lime-pozzolan did not respond in the same way. In lime-clay system, capillarity and carbonation were slightly improved.
