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
Results indicated that polycarboxylate grinding aid (PCGA) obtained by free radical polymerization can provide almost the same grinding efficiency as Triethanolamine (TEA). Besides, PCGA can also optimize the particle size distribution and unify the particle size. The SEM result revealed that the effective was attributed to the function that PCGA reduced the amount of absorbed fine
