Raw Material Substitution
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.
