The use of copper slag in cement and concrete provides additional environmental as well as technical benefits for all related industries. Replacement of copper slag in both fine aggregates
Paver Blocks and Bricks manufacturing process – Replacement of fine aggregate up to 25% (as per CRRI -New Delhi study conducted on copper slag). Concrete Applications – Ferro Sand can replace river sand in fine aggregate up to 50% (as per IIT, Kanpur study report titled "Durability of Cement Concrete using Copper Slag").
The manufacture ofPortland slag cement has been developed primarily to utilize blastfumace slag, a waste product from blastfurnaces. The development of manufacture of this type of cement will considerably increase the total output of cement production in the country and will, in addition. pro vide a profitable use for an otherwise waste product.
