clinker is 4 to 6 (in contrast to 2.3 - 3 of grey Portland cement), and its aluminate module is 15-20 (that of grey Portland cement being 1.5 - 2.5). MS = SiO2/(Al2O3 + Fe2O3) MA = Al2O3/Fe2O3 In view of its low iron content the raw material melts at higher temperatures, at 1420 - 1450°C (conventional Portland cement at about 1250oC) with
