Raw materialsused for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous andargillaceous materialsand gypsum.Calcareous materialscontain limestone or chalk while argillaceousmaterialscomprise an oxide of silica-alumina and iron. Both are found as clay or shale.Get Price

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.Get Price
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.Get Price

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 …Get Price
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.Get Price
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.Get Price
