2 When used in concrete, fly ash is rid of its harmful properties and becomes inert, reducing hazardous risk to the environment. Slag is a by-product that is left over from the production of iron ore through a blast furnace. Molten slag becomes granulated when cooled, and is ground down to a fine powder which can then be used within concrete.
