Raw Material Substitution - Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s 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.
