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.

Sustainable binder materials Frontiers Research Topic

Portland cement (PC) production releases around 1 ton of CO2 per ton of clinker due to the high production temperatures (~1450 °C) in addition to the decarbonation of calcium carbonate (the main raw material of PC). Considering the global production of 4.3 bi tons of PC per year, this sector is responsible for around 8% of the global CO2 released.
