Herewith described invention explains the use of flyingash or its use of a basic raw component in the process of production of portland cement. The other basic raw component in use is a limestone. Flying ash and limestone are mixed in the ratio of masses of 22-26:78-74, respectively. Furthermore described is a process for production of Portland cement, i.e. Portland cement clinker that consists from the phases of homogenization of raw mixture, precalcination at about 900°C, syntherization of clinker at about 1400°C and milling of the, in such a manner obtained, Portland cement. |
