the process of cement manking in iran
Cement
Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.

Alternatives to Cement to Make Construction More Sustainable
23.11.2021It is thus impossible to manufacture cement without producing CO2. Therefore, apart from reducing the amount of CO2 in concrete mixes, proposals to decarbonise cement production focus on capturing CO2 so that it is not released into the atmosphere. Using CO 2 to cure cement can avoid carbon emissions as it remains trapped in solid state.

The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.
