Processes for activation and manufacturing of supplementary cementitious 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 towards incorporation of supplementary cementitious materials to address these challenges, but traditional methods limit the ability to meet national standards. This paper presents concepts for the treatment of raw materials for the manufacture of supplementary cementitious materials. The systems produce a high quality product which allows for increased use in cement blends. The flexibility of these concepts allows for the use of a wide variety of raw materials to produce high quality products with lower fuel consumption and lower emissions over traditional methods.
