The invention discloses high-ductility concrete reinforced by high-strength modified synthetic fibers, the high-ductility concrete is doped with the high-strength modified synthetic fibers, the content of the high-strength modified synthetic fibers in the high-ductility concrete is 1.5 kg/m < 3 >-110kg/m < 3 >, and the high-strength modified synthetic fibers are obtained by modifying synthetic resin or synthetic fibers through a modifier. The high-ductility concrete consists of cement, a cementing material, aggregate, an additive and fibers which are used as raw materials, and high-toughness special concrete is formed by adding water in proportion and stirring. As polar groups such as Si, Si-O,-OH,-COOH and the like are grafted to the surface of the synthetic fiber by the modifier, and the groups act and react with a cementing material in the high-ductility concrete, the strength and dispersion of the fiber and the cohesive force of the fiber and the concrete are greatly improved.
本发明公开了一种高强度改性合成纤维增强的高延性混凝土，高延性混凝土中掺入了高强度改性合成纤维，高强度改性合成纤维在高延性混凝土中的含量为1.5kg/m3‑110kg/m3，高强度改性合成纤维由改性剂对合成树脂或合成纤维进行改性后得到，高延性混凝土由水泥、胶凝材料、集料、外加剂和纤维为原材料组成，按比例加水搅拌、成型的高韧性特种混凝土。由于改性剂将Si、Si‑O、‑OH、‑COOH等极性基团等极性基团接枝到合成纤维的表面，这些基团与高延性混凝土中的胶凝材料发生作用和反应，因此极大提高了纤维的强度、分散和与混凝土的粘结力。
