Abstract
The invention relates to the manufacture of an active belite cement which behaves in the manner of Portland cement at a calcium rating of between 75 and 85, the heating and deacidifying process up to 950 DEG C being unimportant as far as the compressive strength of the cement is concerned, as is the heating process from 950 DEG C up to the sintering temperature which lies within the range between 1350 DEG C and 1450 DEG C. The clinker is subjected to mechanical activation, for example, in a ball mill, either subsequent to grinding in the ball mill or in place thereof, or the active condition of the belite is reached by the cooling process. Cooling is effected by quenching the clinker or tempering it or by gradual cooling, whereby the cooling gradient should be >500 cal/min in the temperature range between from 1350 DEG C to 1250 DEG C (upper limit) and from 1000 DEG C to 800 DEG C (lower limit).
