Zusammenfassung: | A raw mixture for the production of cement consisting of calcareous, aluminous, silicaceous, ferrous, magnesium-containing components and calcium chloride; said components being contained in the raw mixture in the following proportions, per cent by weight: }calcareous component } (calculated for CaO) 30 to 42.3 }silicaceous component } (calculated for SiO2) 12.5 to 17.5 }aluminous component } (calculated for Al2O3) 1.6 to 12.4 }ferrous component } (calculated for Fe2O3) 0.6 to 4.4 }magnesium-containing component } (calculated for MgO) 1.5 to 8 }calcium chloride 6 to 20 }losses at calcination the balance. } The above composition makes it possible to perform calcination of the raw mixture at substantially lower temperatures (within the range of from 1,000 DEG to 1,100 DEG C) and to obtain cement possessing a higher activity. |
