Mar 26, 2015 Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements ...

Ucla Scientists Confirm New Technique Could Make Cement

Sep 25, 2015 During cement manufacturing, there are two steps responsible for carbon emissions. One is calcination, when limestone, the raw material most used to produce cement, is heated to about 750 degrees Celsius. That process separates limestone into a corrosive, unstable solid calcium oxide, or lime and carbon dioxide gas.
