Abstract:Copper, nickel and lead slags of Canadian origin have been studied to evaluate the feasibility of their use as partial portland cement replacement in concrete and mine backfill. Pozzolanic activity of the slags was tested in mortars and the corresponding Ca(OH)2 and non-evaporable water contents at the same age were obtained by thermogravimetric analysis. The relationship between pozzolanic activity and glass content, measured by SEM and image analyzer, was assessed as well. It is concluded that non-ferrous slags could be used as partial Portland cement replacement in concrete and mine backfill if Portland cement and transportation costs justify it.
