DRY GRINDING OF MINERAL MATERIALS, GROUND MINERAL MATERIALS, AND THEIR USE IN CONSTRUCTION MATERIALS
The present invention relates to use of a grinding additive during the dry grinding of mineral materials, especially limestone, characterized in that the grinding additive is selected from the group consisting of alkanolamines, glycols, glycerol, sugars, sugar acids, carboxylic acids or their salts, superplasticizers, superabsorbent polymers, or mixtures thereof. The present invention also relates to ground mineral materials, especially ground limestone, comprising said additives and the use of said ground mineral materials, especially ground limestone, in cement and/or construction materials.
La présente invention concerne l'utilisation d'un additif de broyage pendant le broyage à sec de matériaux minéraux, en particulier le calcaire, caractérisée en ce que l'additif de broyage est choisi dans le groupe constitué par les alcanolamines, les glycols, le glycérol, les sucres, les acides de sucre, les acides carboxyliques ou leurs sels, les superplastifiants, les polymères superabsorbants, ou leurs mélanges. La présente invention concerne également des matériaux minéraux broyés, en particulier du calcaire broyé, comprenant lesdits additifs et l'utilisation desdits matériaux minéraux broyés, en particulier du calcaire broyé, dans du ciment et/ou des matériaux de construction.
