Abstract: A description is provided of the use of an additive including polycarboxylate ether and/or lignosulfonate as grinding aid in cement grinding for producing a cement, especially when fly ash and rock flour are used in the cement. The additive is preferably an aqueous additive. The use of the grinding aid in the production of the cement leads to improved processability of concrete or mortar produced from the cement. In particular, improved stiffening behavior, a reduced water requirement, or a reduced superplasticizer requirement for the mortar or concrete is obtained.

Abstract: Use of an aqueous composition containing at least one polycarboxylate ether as cement grinding aid, wherein the aqueous composition contains one or more additives, or the aqueous composition is used in combination with one or more additives, and wherein the additive is selected from 1,3-propanediol, a carboxylic acid, a sulfonated amino alcohol, boric acid, a salt of boric acid, a salt of phosphoric acid, sorbitol, a saccharide, a gluconate, iron sulfate, tin sulfate, an antimony salt, an alkali salt, an alkaline earth salt, lignin sulfonate, glycerol, melamine, melamine sulfonate and mixtures thereof.
