The invention discloses a preparation technology of high-elastic modulus fiber self-stress recycled concrete. The high-elastic modulus fiber self-stress recycled concrete is prepared from the following components: recycled coarse aggregate, natural coarse aggregate, natural fine aggregate, cement, a superplasticizer, mixed water, fiber, mineral powder, silica fume and rubber particles, wherein thefiber adopts one of high-elastic modulus fiber such as steel fiber, carbon fiber, basalt fiber and fiberglass. According to the preparation technology disclosed by the invention, expansion of internal microdefects of recycled concrete can be relieved by utilizing the high-elastic modulus fiber, and the bending strength, the tensile strength and the toughness of the recycled concrete can be increased; meanwhile, the fiber per se has higher elastic modulus, so that the elastic modulus of the recycled concrete and the rigidity of components can be increased; the strength of the concrete can be increased by utilizing the mineral powder and the silica fume, and creep of the concrete can be reduced; the ductility of the concrete can be increased by utilizing the rubber particles, chloride penetration resistance and the freezing resistance of the recycled concrete can be improved, and the durability of the recycled concrete can be enhanced.
