Manufacturingof cementinvolves variousraw materialsand processes. Each process is explained chemical reactions for manufacture of PortlandCement.Cementis a greenish grey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strong buildingmaterial.

mining ofraw materialincement. Introduction. Sand and gravel are used extensively in construction. In the preparationof concrete, for each tonneof cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b).

Raw materialsforcementmanufacturing. 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.

Objectiveof CementIngredients. The ingredients of ordinarycementas mentioned above, perform the following functions: Lime (CaO) : This is the important ingredientsof cementand its proportion is to be carefully maintained.The lime in excess makes the cements unsound and causes the cements to expand and disintegrate.

Cements may be used alone (i.e., “neat,” as grouting materials), but the normal use is in mortar and concrete in which the cement is mixed with inert material known as aggregate. Mortar is cement mixed with sand or crushed stone that must be less than approximately 5 mm (3/16 inch) in size.

Calculating Quantities ofMaterialsfor per cubic meter or cubic feet or cubic yardsconcrete. Considerconcretewith mix proportion of 1:1.5:3 where, 1 is partof cement, 1.5 is part of fine aggregates and 3 is part of coarse aggregates of maximum size of 20mm.

Common materials used to manufacture cement includelimestone,shells, and chalk or marl combined with shale, clay, slate,blast furnace slag,silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of …

Portland cement, the kind most often used in concrete, is made from a combination of a calcareous material (usually limestone) and of silica and alumina found as clay or shale. In lesser amounts, it can also contain iron oxide and magnesia.

It is generally known that cement is produced from limestone,mar/clayand gypsum by the following three basic process- wet semi- wet and dry process. The cost of exploiting the limestone: the major raw material constitute about 50% of the production cost which results in the high cost of cement.

The production of one ton ofportland cementrequires more than 15 ton ofraw materialsRawmaterialpreparation is an electricity intensive stage, typically requiring 25 to 35 kWh of electricity per ton of processedraw material, although the energy consumption can be as low as 11 kWh/t.
