Cement Production - an overview ScienceDirect Topics

Typical raw materials used for cement production have 85% cayenne, 13% clay or blackboard, and under 1% each of materials such as silica, alumina, and iron ore. These feedstocks are crushed into particles with a diameter of less than 20 mm and mixed with a prehomogenization pile [17] .

Raw materials - Understanding Cement

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.

Concrete Production - an overview ScienceDirect

The cement carbon footprints are issued from two major sources, the decarbonation of lime during the burning process and emissions resulting from the production of heat necessary to increase the temperature up to 1500°C (Fig. 15.3). Some minor emissions can also be attributed to transportation, grinding of raw materials and clinker.

QA: Why cement emissions matter for climate

A further 40% of cement emissions come from burning fossil fuels to heat kilns to the high temperatures needed for this calcination process. The last 10% of emissions come from fuels needed to mine and transport the raw materials. Therefore, cement emissions depend largely on the proportion of clinker used in each tonne of cement.
