摘要：

The present research work is an effort to evaluate the contribution of different nanoparticles in the properties of air lime pastes. The use of nano-silica (NS), nano-alumina (NA) and nano-calcium oxide (NC) can contribute differently in physico-mechanical properties and microstructure. Nanoparticles enhanced compressive strength and open porosity, whilst did not affect significantly the capillarity. Moreover, it was proved that the different mechanisms of nanoparticles' action lead to different carbonation degrees of nano-modified air lime. The microstructure clarified the physico-mechanical results and revealed nano-scale differences in composites. The improvement of the properties of lime-based materials when nano-modified, is the aim of this work in order to improve the inherent weakness of lime and increase the application fields.
