Abstract:
1. A method for producing a hydraulically reactive clinker by sintering a raw meal mixture, which contains sources for CaO, Al 2 O 3 (Fe 2 O 3 ), SiO 2 and SO 3 , wherein the raw meal mixture is sintered in a temperature range of >1200° C. to 1350° C. over a period of time sufficient to convert the raw meal mixture into a clinker intermediate product, the clinker intermediate product is tempered in a temperature range of 1200° C. to a lower limit of 750° C. over a period of time sufficient to obtain 5 to 75 wt % of C the clinker comprising main components C wherein x is a number from 0.1 to 1, is cooled.
