ordinary Portland cement. The use of copper slag reduces the early age strength (1 day) while increasing it beyond 7 days [4]. The use of ground copper slag up to 15% by mass as a Portland cement replacement increased the strength significantly [5]. The addition of copper slag to cement increasedits initial and final setting times [6].
