The invention relates to a stable cement grinding aid. The stable cement grinding aid is characterized by comprising components in parts by weight as follows: 10-20 parts of triethanolamine, 8-12 parts of compound alcohol mother liquor, 5-10 parts of sodium acetate, 1-2 parts of ammonium sulfate, 6-9 parts of urea, 2-6 parts of ethylene glycol, 1-2 parts of calcium lignosulphonate, 2-5 parts of lignin, 1-2 parts of Tween, 5-10 parts of sodium thiosulfate, 1-2 parts of maleic acid, 8-16 parts of fly ash and 6-10 parts of molasses. The stable cement grinding aid has the effects of significantly improving the mill grinding efficiency of cement by 8-15%, properly improving the early strength of the cement by 2-3 MPa and enhancing the later strength of the cement by 2-4 MPa; all the components cooperate with one another, the adaptability of the grinding aid is improved, so that the grinding aid is applicable to different classes of cement, the usage range is enlarged, the grinding aid effect is greatly improved, the output per machine-hour is also increased, the power consumption is reduced, and the mixing amount is low and is 0.02-0.06% per ton of cement.
