Most of the carbon emissions associated with concrete (around 90 per cent) come from the cement content. This is because its production is energy-intensive and difficult to decarbonise with almost three-quarters of its CO 2 emissions resulting from the chemical reactions that take place to produce clinker (the calcination process).

During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for concrete placing. Can I mix plaster with cement? It works well.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400C-1500C in the rotary kiln.
