Stageof Cement Manufacture. There are six main stagesof cement manufacturing process. Stage 1Raw MaterialExtraction/Quarry. Theraw cementingredients needed forcementproduction are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.Get Price
Cement-Cement-History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. Thematerialsused were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementingmaterialof the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.Get Price

Why does themanufacture of cementproduce CO2?Cement manufacturingis the source of 5% of global CO2 emissions. Thecementindustry is a natural producer of CO2: 60% of emissions are due to the transformation ofraw materialsat high temperatures (the "decarbonation" of limestone), 40% result from the combustion required to heat thecement...Get Price
