Properties of Hardened Mortars Containing Crushed Waste

12-09-2019· Mortar mixtures containing different amounts of crushed WOSs (10%, 20%, and 30%) in place of river sand were prepared and compared with mortar containing only river sand (reference). Use of crushed WOSs lowered hardened densities and mechanical properties, but increased water absorption, water permeability, and chloride ion penetration compared with control mortars.
