Blast furnace slag as cement - National Slag Association

Most of the Portland blast-furnace slag cement used in the world is made by inter-grinding the granulated slag with Portland cement clinker. Since the slag is usually the hardest to grind, it forms the coarsest portion of the final product while the cement is ground the finest. The slag is slower setting and, for optimum performance, should be
