The invention discloses a cement composite grinding aid which is characterized by comprising the following components in parts by weight: 10-30 parts of polyol amine, 10-30 parts of polyol, 5-15 parts of molasses, 5-15 parts of lignosulphonate, 2-6 parts of sodium metasilicate pentahydrate, 3-7 parts of sodium hexametaphosphate and 20-30 parts of water. The cement composite grinding aid disclosed by the invention is stable in raw material source, environmental-friendly, low in toxicity and easy to produce, and ensures that the components achieve preferable synergistic effect by confirming the components and a content range, thus optimizing the efficacy of a powder grinding process and improving the power granule distribution and morphology of cement without adverse effect on cement quality. The cement composite grinding aid disclosed by the invention has the advantages of preferably increasing the yield increase and enhancing the cement quality and has the effects of saving the electricity consumption, improving the powder efficiency and the cement strength, reducing the free calcium oxide contained in the cement and enhancing the early strength and later strength of the cement.
