The invention relates to the use of triisopropanolamine in cement grinding aids. 

The cement grinding aid comprises triisopropanolamine, triethanolamine, auxiliaries and water, and the weight percentage of the four is: triisopropyl alcohol Amine 40-100%, triethanolamine 0-15%, auxiliaries 0-25%, water 0-30%, said additive is a kind of carboxylic acid, lignosulfonate, alkyl sulfonate Or more than one.

 The use of triisopropanolamine cement grinding aids has good grinding effect and significantly improves the strength of the later period of the cement. The raw material triisopropanolamine is based in China and reduces the cost of cement grinding, and has broad application prospects.
