A disclosed concrete impact-resistant modifier is prepared from the following raw materials in parts by weight: 1.5-4.7 parts of tribasic lead sulfate, 2.5-4.5 parts of cellulose acetate, 1.2-3.3 parts of rosin-polythylene oxide ester, 1.2-1.9 parts of sodium methyl silicate, 1-3 parts of sodium poly(methylidyne naphthalenesulfonate), 2-3.5 parts of artificial ceramic particle, 0.5-1.3 parts of zinc hydroxide, and 5-10 parts of deionized water. Through the combined effect of the two flexible materials tribasic lead sulfate and cellulose acetate, the concrete possesses high compression resistance, high bending-resistant strength and high impact-resistance flexibility, the elastic modulus of concrete is effectively reduced, the damping ratio of concrete is improved, possibility is provided for vibration damping and noise reduction of concrete pavements, durability of flexible concrete is improved, and the service life of the structure is prolonged.
