| 摘要 |
The present invention relates to a method for the production calcium sulfoaluminate (belite, ferrite) ternesite clinker using fluxes/mineralizers comprising the following steps: providing a raw meal comprising at least sources of CaO, SiO2, AI2O3, SO3, sintering the raw meal in a kiln at >1200 to 1400 °C to provide a clinker, cooling the clinker, wherein a mineralizer comprising at least one compound containing chrome is added prior to sintering providing an amount of chrome calculated as Cr2O3 of at least 500 mg/kg in the raw meal. The invention further relates to the clinker obtained, as well as to calcium sulfoaluminate (belite, ferrite) ternesite cements and binders produced from the clinker. |
