3.2. Workability of the Copper Slag Concrete. Concrete workability refers to its capacity for easy placement, compaction, and finishing without facing issues such as separation or bleeding. Factors such as the water-to-cement ratio, the quantity and nature of the aggregate, and the incorporation of chemical admixtures influence this attribute.

Copper slag is obtained from the copper manufacturing industries as a by-product in smelting process [7]. One tons of copper produces 2.2 tons of waste deposit as a copper slag. Due to heat and electrical conductivity of copper, it has wider applications in terms of wiring and motors, plumbing, cookware's, industrial machinery [17], [18].

Leaching studies of copper from copper slag admixed concrete. 10x10x10cm 3 concrete cubes with water to cement ratio of 0.44 were cast using copper slag. After 24 hours, the mortar specimens were demoulded and kept immersed in various aqueous media such as tapwater, rainwater and sea water. Periodically copper leaching is estimated using AAS.
