<p>The method consists in grinding together clinker of Portland cement, calcium sulfate, mineral substances and solid modifier with the organic water reducer component up to obtaining a specific surface of 350-383 m2/Kg, initiating the chemical reaction between the first ingredient and the last ingredient which takes place during a grinding operation, and treating with water vapor the resulting product with an increase of its specific surface by 30-90 m2/Kg. The grinding and the water vapor treatment may be carried out in various technological plants, particularly in a tubular mill and in an extinction drum, correspondingly.</p> |
