Abstract

Due to worldwide awareness of the need for environmental preservation, considerable weight has been given to developing technologies and methods that promote sustainability, underscoring studies on recycling urban solid waste such as sewage sludge ash (SSA) as a source of raw materials for this industry. Following this tendency, the present study aimed at assessing the technical implications of using SSA as an addition in the preparation of Portland cement concrete on the workability, axial compressive strength, void ratio and water absorption properties of samples produced with 0%, 5%, 10% and 15% of waste in relation to mass of sand used. The results of this study showed that up to 10% of SSA could be added to the concrete mixtures without compromising axial compressive strength, void ratio and water absorption. Moreover, it was found that using this waste induced a loss of workability in the concretes produced.
