Additive for mineral binder with decreased potential for brown discoloration

摘要

Additive composition comprises: at least one grinding aid including glycol, monocarboxylic acid having 1-4 carbon atoms and comb polymer; and at least one retarding agent, where the additive composition is free of organic amines with a molecular weight of less than 500 g/mole, respectively their ammonium salts. An independent claim is also included for producing the mineral components, comprising adding the additive composition before and/or during the grinding process of cement clinker, which is included in a mineral binder, and the amount of the additive composition is 0.005-0.5 wt.%, preferably 0.025-0.1 wt.%, based on the cement clinker to be ground.
