Research on the application of alcohol amine polymer surfactants in cement grinding aids
In this paper,triethanolamine,ethylene glycol,propylene glycol,isopropanolamine,naphthenic acid(sodium),fly ash and organic silicon are used as the main raw materials,and the reasonable ratio of each component is determined through orthogonal experimental design and experiment,under the optimal ratio conditions,triethanolamine:ethylene glycol:propylene glycol:isopropanolamine:industrial salt:fly ash:organic silicon(mass percentage)is 27∶10∶0.14∶0.33∶8∶54.45∶0.08,the development of cement grinding aid has the best grinding effect,and its content is only 0.5‰ of the cement mass.That is,without changing the original cement production process,increase the output of the cement platform by more than 16%,the grinding aid can improve the strength of cement,and the quality of the product,while ensuring the quality of cement,base on the linear relationship between the strength of cemen and the dosage,can save more than 10%clinker usage.
