The invention discloses a cement-base self-leveling mortar which is prepared from the following raw materials: 20-30% of ordinary Portland cement with the standard glue sand strength level of not lower than 42.5, 7-10% of high-alumina cement with the standard glue sand strength level of not lower than 62.5, 5-7% of anhydrous gypsum, 2-4% of high-molecular polymer, 0.2-0.4% of water reducing agent, 0.2-0.4% of defoaming agent, 0.1-0.2% of retarder, 0.1-0.2% of early-strength admixture, 0.2-0.3% of thickener and the balance of filler. Compared with other traditional cement self-leveling mortars, the cement-base self-leveling mortar disclosed by the invention has the advantages of favorable constructability, high early strength, no shrinkage in the later period, favorable wear resistance, beautiful mortar surface and the like.
