Natural pozzolana addition effect on compressive strength and capillary water absorption of Mortar
Energy Procedia, 2017 Abstract The cement manufacturing is the one of the factors that pollutes the atmosphere in the industrial sector. The common way to reduce this pollution is using mineral additives as partial replacement of Portland cement. Particularly, natural pozzolana (NP) is a component in which they can be used to decrease the rate of pollution.
