Get A QuoteThese classicalcalciumsulfoaluminate cements based on yeelimite (C 4 A 3 S ¯) with lesser amounts of C 2 S and C 4 AF, should give lower raw materials-derived CO 2 emissions than OPC. In fact, considering that the thermal energy is mainly used for calcining limestone, the reduction of limestone content in thekilnfeed creates a similar decrease in the energy needed for calcination.
