Cement grinding aid enabling a large amount of limestone to be doped and preparing method of cement grinding aid
The invention relates to the technical field of cement additives, in particular to a cement grinding aid enabling a large amount of limestone to be doped and a preparing method of the cement grinding aid. The cement grinding aid comprises, by mass, 10-20% of triethanolamine, 5-15% of diglycerol, 12-15% of sodium sulfate, 1-5% of sodium chloride, 3-9% of sugar ether, 1-4% of calcium formate, 1-4% of dodecylbenzene, 1-4% of aluminum sulfate, 1-2% of sodium hexametaphosphate, 4-8% of auxiliaries and the balance of water. The cement grinding aid enabling a large amount of limestone to be doped has high dispersity and adsorption capacity and can effectively improve the powder grinding efficiency, improve the fineness, fracture resistance and compressive strength of cement, improve the performance of the cement, increase the yield and reduce the production cost of the cement.
