Portland cement - Michigan State University

Portland cement accounts for more than 95% of all cement produced. To make Portland cement, clay, shale and limestone is ground to a powder and baked in a kiln. The baked mixture forms clods (clinkers), which are then ground up and mixed with gypsum. Most of the raw materials are mined in open pits.
