Addition of Paper Sludge Waste into Lime for Mortar Production

Abstract:

Civil construction materials such as brick, concrete and mortar have been incorporated with compatible wastes aiming at both reducing costs and providing an environmentally correct destination for the waste. In the present work, a sludge waste from a paper industry was added in different amounts, up to 20 wt%, into the lime used to produce mortar in mixture with sand and cement. Standard consistency tests of the pasty, as-prepared, mortar as well as flexural and compressive tests of the solid, as-cured, mortar were performed. The results indicated that the addition of up to 10 wt% of paper sludge waste into the lime increased the mortar consistency and up to 20 wt% addition also improved the mechanical strength of the cured mortar.
