Application of waste concrete large aggregate to concrete structure construction

The invention discloses application of waste concrete large aggregate to concrete structure construction. The concrete structure construction specifically comprises construction of precast beams, precast columns or precast superposed beams; the waste concrete large aggregate is regenerated large aggregate concrete capable of being mixed and poured; and the regenerated large aggregate concrete comprises, per cubic meter, 700-900 kg of regenerated large aggregate, 200-300 kg of a cementing material, 550-650 kg of coarse aggregate, 550-650 kg of fine aggregate, 0-5 kg of a water reducing agent and 110-140 kg of water. Through the invention, the problem that large aggregate distribution is uneven due to stopping of stirrups during pouring is solved, the forming compactness and the structure strength are improved, and the application range of the waste concrete is widened. 本发明公开一种废弃混凝土大骨料在混凝土结构施工中的应用，所述混凝土结构施工具体是指预制梁、预制柱或预制叠合梁的施工；所述废弃混凝土大骨料是可拌制浇筑的再生大骨料混凝土，每立方再生大骨料混凝土包括再生大骨料700-900kg，胶凝材料200-300kg，粗骨料550-650kg，细骨料5
