New approach suggests path to emissions-free cement MIT ...

Sep 16, 2019  Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.

Portland-Limestone Cement

Cement is made by grinding clinker—the main energy intensive ingredient—to a fine powder. Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement.

Cement Manufacturing: Ways to Reduce CO2 Emissions

Feb 11, 2020  Limestone, when heated to above 900 ºC, converts to quick lime (CaO), releasing CO2. The secondary source (40% of total emissions) is the burning of coal/fuel to provide the heat required for the calcination and clinkering process. In terms of weight, roughly 900 g of CO2 is produced as a by-product, for every 1 kg of cement produced.
