  • Slag Cement Questions
    Slag Cement Questions

    Slag cement (also called ground granulated blast furnace slag) is a hydraulic cement produced during the reduction of iron ore to iron in a blast furnace. Molten slag is tapped from a blast furnace, rapidly quenched with water ("granulated"), dried and ground to a fine powder. The rapid quenching "freezes" the molten slag in a glassy state, which gives the product its cementitious properties.

  • Slag: From By-product to Valuable Construction Material
    Slag: From By-product to Valuable Construction Material

    Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.
