Sprayed concrete rebound material recycled concrete
According to the shotcrete springback material recycled concrete provided by the invention, the fine aggregate recycled from the tunnel shotcrete springback material is adopted to replace fine aggregate in concrete components, so that the utilization rate of the waste shotcrete springback material is increased, the exploitation of natural resources is reduced, and the sustainable development of the resources is promoted. The average particle size of the recycled fine aggregate is 0-4.75 mm, the recycled fine aggregate is suitable for manufacturing small prefabricated parts, and no crack caused by concrete shrinkage is found on the surface of the recycled fine aggregate. The recycled concrete disclosed by the invention is not only used for paving a road base, but also realizes high-added-value application of the railway tunnel garbage.
本发明提供了一种喷射混凝土回弹料再生混凝土，本发明采用隧道喷射混凝土回弹料再生的细骨料替代混凝土成分中的细集料，提高了废弃喷射混凝土回弹料利用率，减少了天然资源的开采，推动了资源的可持续发展。本发明再生细骨料的平均粒径为0～4.75mm，适合制作小型预制构件，其表面未发现有任何混凝土收缩引起的裂缝。本发明的再生混凝土不仅用于铺筑道路基层，还实现了铁路隧道垃圾的高附加值应用。
