Thecement manufacturing processstarts from the mining ofraw materialsthat are used incement 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.

Procurement of localraw materialsforms the basis for themanufacture of cement, and represents an essential component of industrial value creation chains in Germany. The most important basematerialsincementinclude limestone, clay or the naturally occurring mixture of the two, lime marl.
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.
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...

The most common raw rock types used in cement production are:Limestone(supplies the bulk of the lime)Clay,marlorshale(supplies the bulk of thesilica,aluminaandferric oxide) Other supplementary materials such assand,fly ash/pulverised fuel ash(PFA), orironstoneto achieve the desired ...
The mainmaterialsused incementproduction are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type ofraw material; therefore, for thecementproduction therawmix is selected for the following components:
