Increasing the corrosion resistance of rebar inside the cement using yttrium oxide nanoparticles

In this work, yttrium oxide nanoparticles were added to cement mortar with one weight percent of cement. To investigate the effect of this nanoparticle on the corrosion resistance of rebar in cement, the polarization test of this sample and the control sample without nanoparticle was performed in a ۳.۵% salt solution. The results showed that the sample has more corrosion potential and less corrosion current with the presence of nanoparticles, which indicates the speed and tendency of corrosion in this sample compared to the control sample. The reason was attributed to the increase in the electrical resistance of the mortar in the presence of nanoparticles
