The production of raw cement involves the extraction and procurement of raw materials like limestone and clay or iron ore. These materials are then crushed and finely ground to form the raw mix. The raw mix is then subjected to high-temperature heating in a kiln, reaching temperatures around 1400°C in a process called clinker.

Because of high carbon concentrations on raw material substitutes of cement such as urban solid-waste incineration residue [161], alternative fuels may not always deserve CO 2 reduction [162]. To address these issues, low-carbon constituents and fuels produced from sustainable and recovering resources are being developed.

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.
