Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.
The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing .
Cement composition is the raw material proportion used in the manufacturing of good quality cement comply with IS 8112 : 1998 of 43 grade OPC and IS 469 for 33 grade. Cement Raw Materials. Cement production mainly consist of Argillaceous and Calcareous raw Material.
Since being patented in 1824 by James Aspdin, OPC (CEMI)has become the world standard in cement production. The basic raw materials needed to produce OPC; limestone, sand and a fuel source, are available on every continent and as a result OPC is readily produced by manufacturers across the globe in an everincreasing number of countries.
Raw materials used for manufacturing of Portland cement are found naturally in the earth crust. It is made primarily from calcareous materials, argillaceous materials and gypsum. Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silicaalumina and iron are found as clay or shale.
Ordinary Portland Cement is the most prevalent because of the readily available raw materials in the area where it is produced. This is also why OPC is an ideal option for cement needs throughout the world today as the costs of producing it is very low without compromising quality.

However, due to low conversion factor from basic raw materials to final product (cement) production volume, the sustainability of manufacture of this type of cement is at stake with respect to raw materials consumption and ...
Cement, as a binding material, is a very important building material. Almost every construction work requires cement. Therefore, the composition of cement is a matter of great interest to engineers. For understanding cement composition, one must know the functionality of Cement ingredients.
Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and is of predominently fine grained cryistalline structure, its hardness is between to of the Mohs scale of hardness and specific gravity 2. To Limestone usually contains admixtures of clay substance or iron compounds, which influnces its colour.
The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.
