Use potential of a paper sludge waste from tissue paper industries in cementitious materials

ABSTRACT

The purpose of this study was to evaluate a paper sludge waste obtained from tissue paper industries regarding its potential for use in cementitious materials. The chemical composition of the waste was assessed and mixtures were made with 0%, 5% and 10% additions of the material, by mass of cement. The cement matrices were analysed experimentally by isothermal calorimetry, compressive strength and tensile strength by diametric compression, water absorption by capillarity, apparent mass density and dynamic modulus of elasticity. The results obtained were not satisfactory, since the addition of the paper sludge waste showed an increase in the cement consumption to reach the required compressive strength, as well as a rise in water consumption in order to maintain the mortar consistency.
