Slag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion.
A blast furnace produces two products: one is the pig iron that is the marketable/usable product and the other is slag that is typically discarded at the site. It was used later for roadkill and also apparently used to make some variants of Depression Glass.last furnace slag is distinctive. It is a dense glass. The colors come both from minerals and elements within the iron ore and the fluxing agent. There is archaeo-metallurgical discussion going on as to whether the process or the ingredients or both and if so, how much of either, if any, influenced the color.
