The invention discloses concrete and a concrete additive thereof and belongs to the technical field of concrete. The concrete additive comprises, by weight, 4-16 parts of coal ash, 4-10 parts of silicon dioxide powder, 4-16 parts of polypropylene fibers, 1-9 parts of calcium powder, 1-9 parts of lignin sulfonic acid calcium powder and 4-10 parts of acrylic emulsion. By the application of the concrete additive, toughness and compressive strength of the concrete can be improved, and service life can be prolonged; the concrete made by the concrete additive is good in tensile strength, fracture resistance and crack resistance, low in cost, simple in production process and applicable to scale production.
