The present invention is related to a family of white clinker compositions with a high capacity of fixing sulfur coming from a high sulfur content pet-coke used as fuel, which further exhibits low fuel consumption and fast setting, which comprises the amounts of clinker phases in percentage by weight : 3CaO.SiO2 (C3S) : 40 to 75, 2CaO.SiO2 (C2S) : 10 to 35, 3CaO.Al2O3 (C3A) : 0 to 15, 3CaO.SO3 (CS) : 0 to 10, 4CaO.3Al2O3 . SO3 (C4A3S) : 2 to 15, 11CaO. 7 Al2O3 CaF2 (C11A7. CaF2) : 0 to 5, total % CaF2 : 0.3 to 1.5 measured as CaF2, % Fe2O3 : 0 to 0.5 and a SO3 content between 1.5 to 5% by weight obtained through the calcinations of a raw meal containing CaO, SiO2 , Al2O3, and CaF2, using as fuel, pet coke with sulfur content higher than 5% at temperatures between 2192 and 24620F, without the addition of any additive containing SO3 in the raw meal.
