Global cement production has reached 3.9 billion tons. However, the clinkerization process, which is the basis of cement production, is responsible for an approximate annual global CO2 emission of 2 billion tons. As part of CEMBUREAU's 5C strategy, the European cement industry aims to achieve carbon neutrality throughout the cement-concrete value …

The raw mix, now called kiln feed, cascades through the preheater system including a pre-calciner and enters the kiln. In the kiln, the bed of material moves toward the burning zone where a reaction takes place and clinker is formed. The hot clinker then passes through a grate cooler where it is cooled and transferred to a storage facility.
Portland cement clinker is manufactured by defined raw materials containing CaO, SiO 2, Al 2 O 3, Fe 2 O 3, MgO, K 2 O, Na 2 O, etc. Homogenous mixtures of raw …
