ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT PRODUCTION. Cement is 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 blending material.
Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the production of lime, as a soil conditioner, or as a popular decorative addition to rock gardens.

Jun 07, 2016· Raw materials used for manufacturing of Portland cement are found naturally in the earth's crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron.
Jan 04, 2016· 43 • The limestone pieces then go through a blender where they are added to the other raw materials in the right proportions 3. Mixing of raw materials Manufacturing of Cement (contd) 37. 44 • The raw materials are ground to a powder. This is sometimes done with rollers that crush the materials against a rotating platform 4.
Secondary raw materials (materials in the raw mix other than limestone) depend on the purity of the limestone. Some of the materials used are clay, shale, sand, iron ore, bauxite, fly ash, and slag. When a cement kiln is fired by coal, the ash of the coal acts as a secondary raw material. Cement grinding
Limestone magnesian rocks, depending on their chemical composition, areraw materials for production of not only air-hardening, but also water lime and portland cement. The quality of carbonate rocks for production of lime in Russia is regulated by OST 21-27-76 "Carbonate rocks for production of building lime".
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

Aug 17, 1971· calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock". Typically, these raw materials are obtained from open-face quarries, but underground mines or dredging operations are also used. Raw materials vary from facility to facility.
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing 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 .

Dec 01, 2018· 5.1. Raw materials. Clays together with limestone are the most abundant materials in the earth's crust. There is a large demand for pure kaolinite clays for the ceramic, refractory and paper industries. The cost of pure metakaolin is in the range 2–3 times the cost of Portland cement.
Limestone is an important raw material for the cement and concrete industries. Especially limestone is the chief raw material for manufacturing of Portland cement. It is also an important raw material in iron and steel making, glass manufacture and sugar refining. Turkey is a major producer of limestone.
Procurement of local raw materials forms the basis for the manufacture of cement, and represents an essential component of industrial value creation chains in Germany. The most important base materials in cement include limestone, clay or the naturally occurring mixture of the two, lime marl.
