A method for grinding a Solid inorganic, inorganic solid and this solid additive for grinding

摘要

A method for grinding an inorganic solid belonging to the series: cement clinker, pozzolanic materials and / or crude material for the production of cement, where a grinding additive is added before or during grinding, and where, based on the dry mass, the grinding additive comprises between 6% and 80% by weight of caprolactam and between 1.5% and 30% by weight of aminocaproic acid, where, based on each case on the dry mass, between 0.002% is used and 2% by weight of the grinding additive, based on total solids. Too,a grinding additive and the use of it to increase the compressive strength of the cured product produced with it. Claim 13: A grinding additive for an inorganic solid belonging to the series of: cement clinker, pozzolanic materials and / or crude material for the production of cement, characterized in that it comprises 6% and 80% by weight of caprolactam, 1.5 % and 30% by weight of aminocaproic acid and 3% and 70% by weight of at least one additional grinding additive belonging to the series of polycarboxylate ethers, lignosulfonate, melamine formaldehyde-sulfonate, naphthalene-formaldehyde-sulfonate mono-,Say...Tri-y polyglicoles, policoholes, alkanes, amino acids, sugars and syrups.
