copper slag in applications such as Portland cement substitution and/or as aggregates has threefold advantages of eliminating the costs of dumping, reducing the cost of concrete, and minimizing air pollution problems. 1.2 Uses of copper slag • Copper slag has also gained popularity in the building industry for use as a fill material.
Slag as replacement of normal crushed coarse aggregate and fine aggregate by [15] was found that the compressive strength increased by 4% to 7%. The workability of self compacting concrete with ground granulated blast furnace slag up to 30% replacement is very good [16].
Aggregate consists of hard, graduated fragments of inert mineral materials, including sand, gravel, crushed stone, slag, rock dust, or powder. Inert solid waste is concrete, asphalt, dirt, brick, and other rubble. Portland cement concrete (PCC) and asphalt concrete (AC) consist primarily of aggregate. The cement and asphalt serve as binders.
