Steel slag, from the converter furnace, is also suited for use in cement manufacturing. Once milled to a fine material, it is absorbed into the mix in the kiln. Cement made with slag aggregate can achieve permeabilities and strengths that compare favourably to concrete made with conventional aggregates.
