The invention discloses a concrete bending-tension resistant modifier, which is prepared from the following raw materials by weight part: 1.5-3.3 parts of an acrylate copolymer, 1.2-2.8 parts of sodium persulfate, 2.5-5 parts of dolomite powder, 1.2-2.4 parts of carrageenan, 2.5-5 parts of polyvinyl alcohol, 0.8-1.6 parts of propyl starch ether, 2.5-3.8 parts of anilmomethyl triethoxy silane, and 1.6-3.2 parts of triphenylethylphenol. According to the invention, the acrylate copolymer and carrageenan are blended into concrete. The combined action of the acrylate copolymer and carrageenan not only can endow concrete with high compressive strength, high bending-tension resistant strength and high anti-impact toughness, but also effectively reduces the elasticity modulus of concrete, and improves the damping ratio of concrete, thus providing possibility for vibration and noise reduction of concrete pavement.
