Abstract

A high volume of marble production generate a considerable amount of waste in the form of odd sizes of stones and slurry during the mining, processing and polishing stages that has a serious impact on the environment. Imperial Smelting Furnace (ISF) slag is a waste generated in the primary extraction of zinc by a pyro metallurgical process with a granular texture. The main goal of this study is utilization of marble mining waste as a partial replacement for conventional coarse aggregate and ISF slag as a partial replacement for sand in concrete mixes. The concrete mixes were designed by using particle packing density approach with a constant water/cement ratio 0.5. In this study the natural coarse aggregate was replaced by 75% marble aggregate and natural sand was replaced by 40% ISF slag by weight. The results of the study show that, the mechanical and durability properties of concrete mixes using these wastes did not have significant adverse impact on properties of concrete.
