    Cement accounts for 83% of total energy use in the production of non-metallic minerals and 94% of C02 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950 C is the main energy consuming process. Portland cement

    May 14, 2020 Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a fuel-intensive
