Efficient concrete performance enhancement additive and preparation method thereof

The invention relates to an efficient concrete performance enhancement additive. The additive is characterized by containing the following components in parts by mass: 10-15 parts of a coupling agent, 4-6 parts of zinc oxide powder, 4-5 parts of activated carbon, 20-25 parts of white carbon black and 30-40 parts of polyester fiber. The additive is prepared by the steps of mixing weighed titanic acid phosphate ester, zinc oxide powder, activated carbon and white carbon black powder into a stirring machine, mixing, distributing to packaging bags according to the weight, and weighing and feeding required polyester fiber into packaged powder bags, so as to obtain a finished product. According to the efficient concrete performance enhancement additive, the impaction resistance, wear resistance, durability, splitting tension strength, axial tension strength and bending strength of concrete are greatly enhanced, the adiabatic temperature rise is decreased, the cracking resistance and the permeability resistance are
