ABSTRACT OF THE DISCLOSURE: A method for regulating the temperature during the production of a building-material composition, wherein the substances corresponding to a particular formula are mixed with one another and heat is supplied or removed during the preparation of the composition. During the whole preparation, the temperature of the mix is measured at short intervals in the region of 0.5 to 30 sec or continuously, with high accu- racy, without contact, and the amount: of heat to be added or subtracted in order to reach the required processing temperature of the composition is calculated. An amount of heat slightly below the calculated value is always supplied or removed, the amount of heat to be supplied or removed approaching the calculated value asymptotically, preferably in stages, or the whole amount of heat corresponding to the calculated value is supplied or removed at one time. An apparatus for carrying out the above described method is also provided. This method and apparatus may be used, for exemple, during the production of cement concrete or asphalt concrete.
