The invention discloses a bending-tension resistant modifier for concrete. The modifier is prepared from the following raw materials by weight: 1.5-3.3 parts of an acrylate copolymer, 1.2-2.8 parts of sodium tripolyphosphate, 2.5-5 parts of dolomite powder, 1.2-2.4 parts of carrageenan, 2.5-5 parts of toluene sulfonic acid, 0.8-1.6 parts of propyl starch ether, 2.5-3.8 parts of aniline methyltriethoxysilane, and 1.6-3.2 parts of triphenylethylphenol. According to the invention, the acrylate copolymer and carrageenan are mixed into concrete, and through the combined action of the flexible materials acrylate copolymer and carrageenan, concrete can have high pressure resistance, high bending tensile strength and high anti-impact toughness, also the elastic modulus of concrete is reduced, and the concrete damping ratio is improved, thus providing possibility for vibration and noise reduction of concrete pavement.
