Theraw materialswhich supplycementworks, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow ofraw materialwill always be available to the kilns.

Use ofraw materialsin thecementindustry Procurement of localraw materialsforms the basis for the manufacture ofcement, 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.

Raw Materials of Cement. Most importantraw materials(what is cement made of) required in the manufacture ofPortland Cementare: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1.

Portland cement consists essentially of compounds of lime ( calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3 ). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

Cement is manufactured through a closely controlled chemical combination ofcalcium,silicon,aluminum,ironand other ingredients. Common materials used to manufacture cement includelimestone,shells, andchalkor marl combined withshale,clay, slate,blast furnace slag,silica sand, andiron ore.

Lime Component Limestone: Common forms of calcium carbonate used asraw materialforcementmanufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT PRODUCTION.Cementis a complete mixture of mineral substances that gradually harden when mixed with water. It is the product of the reaction of lime with the oxides of silica alumina and iron. It is used in the construction of industry as a blendingmaterial.
