Abstract
Traditional treatment techniques in raw water treatment plants produce massive quantities of sludge globally. Due to the chemical makeup of sludge, stringent environmental regulations are necessary to avoid the adverse environmental effects connected with the disposal of such a massive waste stream. In the cementitious matrix, it has been proposed to use post-coagulation-flocculation sludge created artificially. In the present study, sludge was utilized as a partial replacement for cement in the mortar mixture in order to lower the amount of natural contents. The addition of sludge altered the mortar’s composition and performance. This study aims to determine the optimal replacement percentage of sludge with cementitious material based on the compressive strength of mortar cubes. In general, compressive strength declines as sludge concentration increases. The maximum compressive strength was achieved at 10% sludge replacement. The experimental results revealed that the mortar containing 10% water treatment sludge (WTS) is suitable for building and construction since its strength varies with replacement levels.
