The effects of limewater on split tensile strength and workability of Al2O3 nanoparticles binary blended concrete
The effect of limewater on split tensile strength and workability 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 nanofillers. 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 maximum replacement level of 2.0% produce concrete with improved split tensile strength but reduced workability when the specimens are cured in saturated limewater with respect to the specimens which are cured in water. Al2O3 nanoparticles can improve the filler effect and also the high pozzolanic action of fine nanoparticles increases substantially the quantity of strengthening gel. Although the limewater reduces the strength of concrete without nanoparticles, curing the specimens in saturated limewater enhances the gel formation in concrete blended with Al2O3 nanoparticles.
