Abstract

In this study, aluminum white-powdered sludge, which is an industrial waste product from the aluminum-anodizing industry, is used as an admixture in cement paste to observe its effects on the mechanical properties and the corrosion resistance in the reinforced steel bars. The mass ratio of cement and aluminum white-powdered sludge (particularly 1.00:0.05, 1.00:0.1, and 1.00:0.2) is used to prepare cement paste by using 48.5 wt.% water ratio. The effect of the mass ratio of cement and aluminum whitepowdered sludge (average particle size of the aluminum white-powdered sludge is less than 45 μm in diameter) on porosity, bulk density, compressive strength, and corrosion resistance have been centered around for this study. Based upon the results of study, as the quantity of the aluminum white-powdered sludge increases, the porosity of cement paste also increases; yet the bulk density and compressive strength of the paste, on the other hands, decrease. However, it was found that the addition of the aluminum whitepowdered sludge to the cement paste causes more corrosion on reinforced steel bars and also more damaged on the cement pastes.
