  • 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.

  • Ground Granulated Blast Furnace Slag (GGBS) Chemical

     · This slag is periodically tapped off as a molten liquid and then rapidly quenched with large volumes of water. This process optimizes the cementitious properties and produces granules like coarse sand. This granulated slag is then dried and ground to a fine powder. It is also knows as slag cement because it has similar properties as cement clinker.
