Copper slag is a by-product obtained during the smelting and refining of copper, and it has found significant use in the construction industry due to its durability, hardness, and eco-friendly properties. With its coarse, granular texture and high specific gravity, copper slag serves as an effective replacement for natural sand in concrete production. It enhances the compressive strength, workability, and long-term durability of concrete, making it ideal for structures that demand strength and resistance to wear. Apart from concrete, copper slag is used in road construction as a sub-base material, in embankment filling, and in the production of bricks and tiles.
