principles of cement manufacturing process

Trends and developments in green cement and concrete

The cement is referred to as a carbon negative product not just because of the fuel it uses but also because the CO 2 it produces in the manufacturing process is recycled back into the process. The production of 1 tonne of Novacem hydrated magnesium carbonate cement supposedly absorbs up to 100 kg more CO 2 than it emits.

Cement Manufacturing Process: What is Cement made of.

At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Manufacture of Portland Cement

The Cement Manufacturing Process. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.

Concrete: Scientific Principles

The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
