and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. 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.

The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The chemical composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an argillaceous component of raw mix.

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 locally-available raw materials which make up the bulk of the raw meal.

Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180-250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement.

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components:

The initial production step in portland cement manufacturing is raw materials acquisition. Calcium, the element of highest concentration in portland cement, is obtained from a variety of calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock".

Manufacture of Cement. To manufacture cement first of all limestone is added into the clay in proportion of 3:1 by weight. This mixture of limestone and clay is then dried and crushed to get a fine powder called ‘raw meal’. The raw meal is then added into a rotary kiln through a hopper as shown in figure.

Producing cement consumes both large quantities of raw materials and fuel, and produces substantial CO2 emissions. The use of alternative fuels and raw materials in cement manufacturing can reduce the amount of conventional fuels and raw materials needed, and thus reduce the overall environmental impact of the operations.
