Abstract

In this paper, the effects of using Cr₂O₃ and ZnO₂ nanoparticles on the mechanical properties and durability of self-compacting mortars are investigated. A fraction of Portland cement was replaced with 1, 2, 3, 4 or 5 wt.% of either Cr₂O₃ or ZnO₂ nanoparticles, and 25 wt.% fly ash. The rheological properties of these mortars were determined through the mini-slump flow diameter and V-funnel flow time tests. The mechanical and durability characteristics were evaluated by compressive and flexural strength, water absorption, electrical resistivity and rapid chloride permeability tests. The microstructure of the mortars was assessed through the use of scanning electron microscopy. The inclusion of 2 wt.% Cr₂O₃ or 4 wt.% ZnO₂ nanoparticles had the best result in compressive and flexural strength tests. Also, mixtures containing either 3 wt.% of Cr₂O₃ or 5 wt.% of ZnO₂ nanoparticles obtained the best result in terms of durability. It can be deduced that the properties of these mixtures are significantly improved by the addition of Cr₂O₃ and ZnO₂ nanoparticles.
