Tailing sand aggregate, ultra-high performance concrete and application thereof
The invention provides a tailing sand aggregate and application thereof. The tailing sand aggregate comprises tailing sand of 40-90 meshes, tailing sand of 90-400 meshes and tailing sand of 400-1250 meshes, wherein the mass ratio of the tailing sand to the tailing sand of 40-90 meshes to the tailing sand of 90-400 meshes to the tailing sand of 400-1250 meshes is 1: 0.6-3: 0.4-2. When the tailing sand aggregate provided by the invention is used for preparing concrete, close packing of the concrete can be realized, so that the concrete has higher fracture resistance and compressive strength. The invention also provides the ultra-high performance concrete which comprises 30-85 wt% of the tailing sand aggregate. According to the ultrahigh concrete provided by the invention, the adding amount of the tailing sand aggregate is high, the utilization rate of the tailing sand solid waste is high, and meanwhile, close packing of the concrete can be realized by adopting the tailing sand aggregate, so that the concrete has higher fracture resistance and compressive strength. The ultra-high performance concrete provided by the invention can be applied to the fields of building materials, pavement materials, bridge engineering and the like.
本发明提供一种尾矿砂骨料及其应用，所述尾矿砂骨料包括质量比为的1:0.6~3:0.4~2的40‑90目、90‑400目、400‑1250目尾矿砂。本发明提供的尾矿砂骨料用于混凝土制备可实现混凝土的紧密堆积，进而使该混凝土具有更高的抗折和抗压强度。本发明还提供一种超高性能混凝土，包括30‑85wt%的所述尾矿砂骨料。本发明提供的超高混凝土，所述尾矿砂骨料掺加量高，尾矿固废利用率高，同时，采用上述尾矿砂骨料可实现混凝土的紧密堆积，进而使该混凝土具有更高的抗折和抗压强度。本发明提供的超高性能混凝土可应用于建筑材料、路面材料和桥梁工程等领域中。
