    The raw meal also contained limestone and corrective materials (bauxite and iron oxide) but marls were not used. The clinker produced contained free lime rates similar to the standard clinker production. Conclusion. Replacement of Portland clinker raw materials by RA is promising but challenging because of the variability in the RA composition.
