  • What is slag cement

    Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield

  • Slag Cement Questions

    Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.

  • Why use Fly Ash and Slag in Concrete? Bay-Lynx

    Slag happens when iron ore is melted. The molten iron sinks to the bottom, while the slag will float on the top of the iron. See the diagram below: Another difference between slag and fly ash is that while fly ash will rarely surpass 35% of the cement content, slag can substitute 50% of the cement content, or even higher for different applications.
