An Evaluation of the Effect of Waste Aluminum Sawdust on the Carbonation of Concrete

The aim of this study is to examine the effect replacing waste aluminum sawdust (AS) with fine aggregate on strength and durability properties concrete. For this, concrete mixtures a cement dosage 400 kg/m3 water/cement (W/C) ratio 0.40-0.50-0.60 were prepared. AS obtained from Elazig industrial site was added by 0%, 0.5% 1% volume. After curing in pool for 28 days, produced samples subjected accelerated carbonation test tank at three different time periods 1st, 3rd 7th days. Compressive depth measurement performed before after carbonation. In addition, microstructure investigated using scanning electron microscopic images (SEM). images, larger cracks, openings interfacial voids observed matrix addition AS. it has been that contributes compressive strength.
