The invention relates to the technical field of concrete, and particularly discloses high-performance coal gangue lightweight aggregate concrete and a preparation method thereof. The high-performance coal gangue lightweight aggregate concrete prepared by the invention has a self-heat-preservation characteristic, is excellent in sound insulation and floor impact sound insulation effect, is beneficial to saving building materials, and reduces shrinkage cracking of the surface. The concrete disclosed by the invention is suitable for adopting a full-spiral conveying and automatic batching process, the graded pottery sand prepared industrially is beneficial to realizing a self-leveling effect, the construction difficulty is reduced, the defect of poor freeze-thaw resistance of ceramsite lightweight aggregate concrete in related technologies is overcome, and high-quality guarantee of construction is realized. According to the concrete, the industrial solid waste is successfully used for replacing natural gravel, an
