Unfired iron tailing ceramsite, pervious concrete and preparation method of unfired iron tailing ceramsite
The invention relates to unfired iron tailing ceramsite, pervious concrete and a preparation method of the unfired iron tailing ceramsite. The unfired iron tailing ceramsite is prepared from the following raw materials: 50-60 parts of iron tailing powder, 20-30 parts of cement, 2-5 parts of glass fibers, 1-5 parts of VAE rubber powder, 0.1-0.5 part of a water reducing agent, 0.1-0.5 part of an early strength agent and 20-25 parts of water. The prepared iron tailing ceramsite pervious concrete is excellent in performance, the slump and the expansion degree of the pervious concrete are slightly different from those of conventional concrete of the same specification, the compressive strength of the pervious concrete is better than that of the conventional concrete, and compared with the conventional concrete, the weight of ceramsite is relatively light, and the capacity of the concrete is light. The weight of a poured concrete structural part is light, the pressure borne by a foundation is much smaller, and the pervious concrete can improve the bearing capacity of the concrete structure on the premise of meeting the use requirements of actual working conditions; the preparation method of the ceramsite and the concrete is simple, and the operation process is convenient and rapid.
本发明涉及一种免烧铁尾矿陶粒、透水混凝土及其制备方法，所述的陶粒包括如下原料制成：铁尾矿粉50‑60份、水泥20‑30份、玻璃纤维2‑5份、VAE胶粉1‑5份、减水剂0.1‑0.5份、早强剂0.1‑0.5份和水20‑25份。本发明制备的铁尾矿陶粒透水混凝土性能优良，所述的透水混凝土的坍落度、扩展度与同规格的常规混凝土相差不大，其抗压强度要优于常规混凝土，相对常规混凝土而言，陶粒重量相对较轻，混凝土的容重要轻。浇筑好的混凝土结构件重量要轻，地基承受的压力也要小的多，透水混凝土在满足实际工况使用需求的前提下，还能提高混凝土结构的承载性；本发明的陶粒及混凝土的制备方法简单，操作过程方便快捷。
