The invention relates to a cement material, in particular to a liquid cement grinding aid. The liquid cement grinding aid comprises the following components in percentage by weight: 20-30 percent of an aqueous solution of sodium salt of acrylic acid-maleic anhydride copolymer, 15-25 percent of a sodium salt water-reducing agent of aminobenzene sulfonic acid, 5-10 percent of sodium lignin sulfonate, 5-10 percent of glycol, 10-15 percent of triethanolamine, 1-5 percent of sodium gluconate and the balance of water. The invention aims to provide the liquid cement grinding aid with the effect of improving the early strength and later strength of cement.
