The effects of limewater on flexural strength and water permeability of Al2O3nanoparticles binary blended concrete
The effect of limewater on flexural strength and water permeability of Al2O3 nanoparticles binary blended concrete has been investigated. Al2O3 nanoparticles with partial replacement of cement by 0.5, 1.0, 1.5, and 2.0 wt% have been used as reinforcement. Curing of the specimens has been carried out in water and saturated limewater for 7, 28, and 90 days after casting. The results indicate that Al2O3 nanoparticles up to a maximum replacement level of 2.0% produce concrete with improved flexural strength and water permeability when the specimens are cured in saturated limewater compared to the specimens cured in water. Al2O3 nanoparticles improve the filler effect. The high pozzolanic action of the nanoparticles increases substantially the quantity of the strengthening gel. Although the limewater reduces the strength of concrete without nanoparticles, curing the specimens in saturated limewater results in more strengthening gel formation in concrete blends containing Al2O3 nanoparticles.
