The invention relates to the technical field of concrete, in particular to a concrete additive. The concrete additive comprises the following components in parts by weight: 10-30 parts of modified cement, 10-20 parts of modified bentonite, 1-3 parts of nanometer silicon dioxide, 1-5 parts of a water reducing agent, 0.3-0.8 part of alkyl sodium sulfonate, 10-20 parts of gypsum powder, 1-5 parts of a wet dispersing agent, 0.3-0.8 part of a stabilizing agent, 0.2-0.5 part of an anti-freezing agent, 1-6 parts of a corrosion inhibitor and 10-25 parts of deionized water. The concrete additive has the beneficial effects that the compressive property of concrete can be greatly improved, and meanwhile, the durability of the concrete can be improved; the modified cement and the modified bentonite are utilized, so that the penetrating performance is greatly improved; besides, the corrosion inhibitor and the anti-freezing agent are added, so that performances of concrete are improved from multiple aspects, the service life of the concrete is prolonged, and the maintenance cost of a concrete building is reduced.
