The invention discloses concrete and a modifier thereof, belonging to the technical field of concrete. The modifier of concrete comprises the following raw materials in parts by weight: 5-10 parts of coal ash powder, 2-6 parts of silicon dioxide powder, 2-6 parts of gypsum powder, 5-10 parts of Grace fibers, 2-6 parts of steel fibers, 3-9 parts of calcium powder, 1-9 parts of dispersible emulsion powder, 1-5 parts of acrylic emulsion, 1-5 parts of calcium carbonate, 1-5 parts of zinc sulfate, 5-10 parts of sodium borate and 4-12 parts of polyacrylamide. The modifier of concrete can conduce to improving the toughness and compressive strength of concrete and prolonging the service life of concrete. The concrete prepared by adopting the modifier of concrete has good tensile, flexural and anti-cracking properties, is low in price, simple in production process and low in cost and is suitable for large-scale production.
