Supplementary Cementitious Materials: Concepts for the Treatment of Raw Materials

The cement industry is under increasing pressure to provide environmentally friendly and sustainable products while also meeting more stringent emissions standards. Globally, cement producers are trending toward the incorporation of supplementary cementitious materials (SCMs) to address these challenges, but traditional methods limit the ability to meet national standards. This article presents concepts for the treatment of raw materials for the manufacture of supplementary cementitious materials. The systems produce a high-quality product, allowing increased use in cement blends. The flexibility of these concepts permits the use of a wide variety of raw materials to produce high-quality products with lower fuel consumption and lower emissions compared to the traditional methods.
