chemical reaction of cement production

Cement production is responsible for around 7% of worldwide greenhouse gas emissions. The only larger contributors are electricity generation and transport. Most of the CO 2 released when cement is made comes from the chemical reaction. The limestone from which it is made iscalcium carbonate, and when this is heated it gives off carbon dioxide, and formscalcium oxide.
