Natural gypsum is mined as a natural raw material for use in building products such as drywall, cement additives and plaster. It is also used as a fertilizer and as the main
The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60 of the industrys CO 2 emissions are caused by transformation of limestone into lime, called decarbonation. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
