Self-compacting recycled concrete containing seawater-eroded recycled aggregate and preparation method of self-compacting recycled concrete
The invention relates to the technical field of building materials, and particularly discloses self-compacting recycled concrete containing seawater erosion recycled aggregate and a preparation method thereof.The self-compacting recycled concrete is prepared from, by weight, 563.3-586.9 parts of gel material, 728-768 parts of modified recycled fine aggregate, 759-799 parts of modified recycled coarse aggregate, 5.75-17.27 parts of composite fiber, 158-182 parts of water and 8.45-8.80 parts of water reducing agent, the modified recycled coarse aggregate is prepared from recycled coarse aggregate prepared from existing marine buildings, the recycled fine aggregate is subjected to carbonization treatment, and the composite fiber is prepared by mixing polypropylene fiber and carbon fiber. The recycled aggregate eroded by seawater is utilized to prepare the concrete, the in-situ taking rate of the raw materials reaches 70% or above, and the concrete has the advantages of self-compacting property, high strength, greenness, environmental protection and the like.
本申请涉及建筑材料技术领域，具体公开了一种含海水侵蚀再生骨料的自密实再生混凝土及其制备方法，包括如下重量份数的原料：凝胶材料563.3‑586.9份、改性再生细骨料728‑768份、改性再生粗骨料759‑799份、复合纤维5.75‑17.27份、水158‑182份、减水剂8.45‑8.80份，其中，改性再生细骨料、改性再生粗骨料由源于海洋既有建筑制成的再生粗骨料、再生细骨料经碳化处理制得，复合纤维由聚丙烯纤维、碳纤维混合制得。本发明将受海水侵蚀的再生骨料利用起来制备混凝土，原材料就地取用率达到70％以上，具有自密实属性，强度较高，绿色环保等优点。
