Cement kiln - Wikipedia
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Decarbonising the cement industry | World Cement
Decarbonising the cement industry. Cement manufacture accounts for roughly 7% of total manmade CO 2 emissions. Today, cement and concrete producers are demanding more sustainable ways to produce these materials. The good news is that approximately one third of targeted CO 2 reduction can be realised through clinker replacement.
New approach suggests path to emissions-free cement | MIT ...
Caption: In a demonstration of the basic chemical reactions used in the new process, electrolysis takes place in neutral water. Dyes show how acid (pink) and base (purple) are produced at the positive and negative electrodes. A variation of this process can be used to convert calcium carbonate (CaCO3) into calcium hydroxide (Ca(OH)2), which can then be used to make Portland cement without ...
