The proportions of each mineral in the clinker are important in determining the properties of the resulting cement. For example, in some special cements, such as Low Heat (LH) and Sulphate Resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate (3CaO-Al 2 O 3 ) that is formed.

3.1 CO2 Cement Production IGES

2003-2-25  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 combustion and is accounted for elsewhere. However, the CO2 from fossil fuels is accounted for elsewhere in emission estimates for fossil fuels. The Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Guidelines) provide a general approach to estimate CO2 emissions from clinker production, in which the amount of clinker produced is multiplied by the clinker

Temperatures over 900°C transform the limestone (CaCO 3) into lime (CaO), thus releasing CO 2. This is called the calcination process. The calcinated raw meal reaches temperatures of up to 1450°C which allow its sintering to form clinker.
