Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily fromcalcareousand argillaceous materials andgypsum. Calcareous materials containlimestoneor chalk while argillaceous materials comprise an oxide ofsilica-aluminaandiron. Both are found asclayorshale.
RAW MATERIALSINCEMENTPRODUCTION February 07, 2019 · Archive · 0. 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 theraw mixis selected for the following components:
The second important raw material for cement production isclay.The main component ofclayis formed byhydrous aluminium silicates.The chemical composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures asiron hydroxide,iron sulfide,sand,calcium carbonate, etc.Clayis used as an argillaceous component of raw mix.
To mine thechief raw materialfor the manufacture ofcement-limestonerequires a lot of machines, plants and explosives. A lot of money is also paid as compensation to the communities that own the land. All these expenditures lead to thehigh costofcement.
The most common raw rock types used in cement production are:Limestone(supplies the bulk of thelime)Clay,marlorshale(supplies the bulk of thesilica,aluminaandferric oxide) Other supplementary materials such assand,fly ash/pulverised fuel ash(PFA), orironstone…

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.
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.
Theraw materialsneeded to producecement(calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. Theseraw materialsare extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
Cement-Cement-Extraction and processing:Raw materialsemployed in the manufacture ofcementare extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
A responsibleraw materialspolicy must therefore create reliable framework conditions for sustainable supply ofraw materials. This is the only way that companies will be able to obtain the planning and investment security required to continue to be able to cover requirements for top-qualitycement-bound buildingmaterialsin future.
Thecement manufacturing processstarts from the mining ofraw materialsthat are used incementmanufacturing, 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.
Cement manufacturing process & what is cementmade of, it can be discussed conveniently under two headings: Selection ofRaw materialsand manufacturing methods.Raw MaterialsofCement. Most importantraw materials(what iscementmade of) required in the manufacture of PortlandCementare: Limestone, Clay, Gypsum, Fuel, and Water (in wet method).

We use alternativeraw materialsfor the production of clinker, which is the most important intermediate product in the manufacture ofcement. In this way we reduce the amount of CO 2 intensive clinker in the final product. The increased use of alternativeraw materialsincementproduction is thus a core element of our climate strategy. At ...

Concretemanufacturers expect theirraw materialsuppliers to supply a consistent, uniform product. At thecementproduction factory, the proportions of the variousraw materialsthat go intocementmust be checked to achieve a consistent kiln feed, and samples of the mix are frequently examined using X-ray fluorescence analysis.
