CLINKER AND WHITE PORTLAND CEMENT WITH A HIGH SULFUR CONTENT DERIVED FROM A HIGH SULFUR CONTENT PET-COKE USED AS FUEL

摘要

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.SI02 (C3S): 40 TO 75, 2CAO.SI02 (C2S): 10 TO 35, 3CAO.A12O3 (C3A): 0 TO 15, CAO.S03 (CS): 0 TO LOT 4CAO.3A12O3.S03 (C4A3S): 2 TO 15, 11CAO. 7A12O3 .CAF2 (C11A7. CAF2): 0 TO 5, TOTAL % CAF2: 0.3 TO 1.5 MEASURED AS CAF2T % FE203: 0 TO 0.5 AND A S03 CONTENT BETWEEN 1.5 TO 5% BY WEIGHT OBTAINED THROUGH THE CALCINATION OF A RAW MEAL CONTAINING CAO, SI02, A12O3, AND CAF2, USING AS FUEL, PET-COKE WITH A SULFUR CONTENT HIGHER THAN 5% AT TEMPERATURES BETWEEN 1200OC AND 1350OC (2192°F AND 2462°F) T WITHOUT THE ADDITION OF ANY ADDITIVE CONTAINING SO3 IN THE RAW MEAL.
