Manufacturing process | Lafarge - Cement, concrete,

The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers,Emissions from the Cement Industry - State of the Planet,Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.Limestone Calcined Clay Cement - Wikipedia,Limestone Calcined Clay Cement is a low-carbon alternative to the standard Portland cement.
