This paper studies the effect of clinkering temperature and duration on the production, phase evolution and microstructure of low energy Belite Calcium-Sulpho-Aluminate (BCSA) clinkers. The mineralogy and microstructure of BCSA clinker, produced in the temperature range of 1270–1340 °C and clinkering duration periods of 20, 30 and 60 min, were studied by XRD/QXRD and SEM/EDS.
