The invention discloses an efficient cement grinding aid and cement containing the same and belongs to the field of cement production. The cement grinding aid comprises the following raw materials in parts by weight: 3-9 parts of alkyl polyglucosides, 2-6 parts of sodium tripolyphosphate, 2-6 parts of triisopropanolamine, 3-9 parts of polyethyleneglycol, 2-6 parts of sodium acetate, 2-6 parts of unsaturated polyester resin, 4-12 parts of diglycolamine, 3-9 parts of ligninsulfonate, 3-9 parts of sodium thiosulfate, 2-6 parts of ethoxyl diethylene triamine, 3-9 parts of sodium gluconate and 2-6 parts of glycerol. Meanwhile, the invention further discloses the cement containing the enhanced cement grinding aid. The efficient cement grinding aid is low in mixing amount and good in enhancement effect, can improve the cement performance and the machine-hour yield, and reduces the cement production cost, and the cement provided by the invention is small in clinker ratio, can reduce environmental pollution and saves mineral resources.
