(Blaine), and comprising in terms ofchemical composition, for each 100% by weight, at least about 60% by weight tricalciumsilicate (C₃S), at least about 9% by weight tricalcium aluminate (C₃A), at least about 4% byweight tetracalcium aluminoferrate (C₄AF), no more than about 4% by weight dicalciumsilicate (C₂S), and at least 3% by weight of a calcium sulfate, calculated as SO₃).
