Production and preparation method of self-compacting concrete doped with tailings
The invention provides a tailing-doped self-compacting concrete production and preparation method, the tailing-doped self-compacting concrete is composed of coarse aggregate, tailing sand, fly ash, cement, water and an additive, the blending proportion of each grade of the coarse aggregate is determined according to a volume step-by-step filling method, the coarse grade of the aggregate is wrapped by the fine grade of the aggregate, and the coarse grade of the aggregate and the fine grade of the aggregate do not interfere with each other; according to a particle size synthesis method, the blending proportion of the tailing sand and the fly ash is determined, and residual gaps of the self-compacting concrete are completely filled with the mucilage material after the coarse aggregate and the filler are wrapped with the mucilage material; calculating the dosage of the adhesive film according to the volume change before and after the coarse aggregate and the filler are coated with the adhesive film with certain thickness, and further determining the dosage of the self-compacting concrete raw material. The materials are mutually non-interfering in space, the volume stability is ensured, the cement mortar wraps the coarse aggregate and the filler to form an optimal strength state, the performance of the self-compacting concrete is controllable by adjusting related parameters, and the solid waste materials such as the tailing sand and the fly ash are doped, so that the recycling of the solid waste is realized.
本发明提供一种掺尾矿的自密实混凝土生产制备方法，由粗骨料、尾矿砂、粉煤灰、水泥、水以及外掺剂组成，粗骨料按照体积逐级填充方法确定各档掺配比例，粗一档集料被细一档包裹，相互不干涉；按照粒径合成方法，确定尾矿砂和粉煤灰掺配比例，胶浆材料包裹粗骨料、填料后完全填满自密实混凝土剩余空隙；通过粗骨料、填料包裹上一定厚度胶浆膜前后体积变化，计算胶浆膜用量，进而确定自密实混凝土原材料用量。本发明材料之间在空间构成相互不干涉，保证体积稳定性，水泥胶浆包裹粗骨料、填料形成最佳强度状态，通过相关参数的调整，实现自密实混凝土性能可控，掺入尾矿砂、粉煤灰等固废材料，实现固体废弃物的再生使用。
