The invention discloses a concrete high-efficiency water reducer. The water reducer comprises the following raw materials in parts by weight: 20-40 parts of unsaturated alcohol-polyoxyethylene ether,10-30 parts of sodium lignin sulfonate, 10-20 parts of acrylic acid, 5-10 parts of modified starch, 3-8 parts of aloe gel, 2-6 parts of cyclodextrin, 2-5 parts of cross-linked povidone, 2-5 parts of zinc gluconate, 1-3 parts of sodium polystyrenesulfonate, 1-3 parts of sodium alginate, 0.5-2 parts of graphene oxide, 0.2-1 part of sodium silicate, 0.1-0.5 part of a defoaming agent and 3-5 parts ofan initiator. The high-efficiency water reducer prepared by the method is good in stability, and can increase workability of concrete when used in the concrete. In addition, the water reducer can be mixed with other water reducing agents for use, the water adding amount is reduced, the solidification time of concrete is shortened, and strength of the concrete is improved.
