3.1 CO2 Cement Production - IGES

Cement is an important construction ingredient produced in virtually all countries. Carbon dioxide (CO2) is a by-product of a chemical conversion process used in the production of clinker, a component of cement, in which limestone (CaCO3) is converted to lime (CaO). CO2 is also emitted during cement production by fossil fuel
