摘要
The invention discloses a White Portland cement clinker, with the capacity to fix sulfur derived from an organic fuel having a sulfur content greater than 5% S, used as a fuel in the calcination of said clinker, said clinker additionally exhibiting reduced fuel consumption during such calcination and useful for producing a fast setting cement, characterized in that said clinker comprises amounts of clinker phases in percentage by weight, as follows: 3CaO.SiO2 (C3S): 40 to 75, 2CaO.SiO2 (C2S): 10 to 35, 3CaO.AI2O3(C3A): 0 to 15, CaO.SO3(CS): 0 to 10, 4CaO.3AI2O3.SO3 (C4A3S): 2 to 15, 11CaO.7AI2O3.CaF2 (C11A7CaF2): 0 to 5, %CaF2Total: 0.3 to 1.5 measured as CaF2, %Fe2O3: 0 to 0.5, and a SO3 content between 1.5 and 5% by weight obtained through the calcination of a raw meal comprising CaO, SiO2, Al2O3 and CaF2, and using an organic fuel with a sulfur content higher than 5% as the main source of the clinker's SO3 content, at temperatures between 2192 °F and 2462 °F, without the addition of any SO3-containing additive to the raw meal as a main source of SO3 content in the clinker. The invention is also for a method of its production and white Portland cement comprising it.
