how is mill scale used in concrete production

  • Mill scaleWikipedia

    In refractory production. Mill scale can be used as a raw material in granular refractory. When this refractory is cast and preheated these scales provide escape routes for the evaporating water vapor thus preventing cracks and resulting in a strong monolithic structure.
