The invention discloses high-strength modified synthetic fiber reinforced reactive powder concrete. High-strength modified synthetic fibers are doped into the reactive powder concrete, wherein the content of the high-strength modified synthetic fibers in the reactive powder concrete is 0.1-100 kg/m3; the high-strength modified synthetic fiber is obtained by modifying synthetic resin or synthetic fiber with a modifier, wherein the active powder concrete is produced by taking cement, mineral admixtures and other active powder materials, fine aggregate, additives and water as raw materials. Due to the fact that polar groups such as Si, Si-O, -OH and -COOH are grafted to the surface of the synthetic fiber through the modifier, so that the groups react with active powder minerals in the activepowder concrete, and the strength, dispersion and binding power with the concrete of the fiber are greatly improved.
本发明公开了一种高强度改性合成纤维增强的活性粉末混凝土，活性粉末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活性粉末混凝土中的含量为0.1kg/m～100kg/m，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，活性粉末混凝土为以水泥和矿物掺合料等活性粉末材料、细骨料、外加剂、水为原料生产的混凝土。由于改性剂将Si、Si‑O、‑OH、‑COOH等极性基团接枝到合成纤维的表面，这些基团与活性粉末混凝土中的活性粉末矿物质发生作用和反应，因此极大提高了纤维的强度、分散和与混凝土的粘结力。
