High-performance concrete based on antimony tailings barren rock and preparation method thereof
The invention relates to high-performance concrete based on antimony tailings and barren rock and a preparation method of the high-performance concrete. The high-performance concrete comprises the following materials: coarse aggregate, machine-made sand, a water reducing agent and water, wherein the coarse aggregate comprises cement and antimony tailings macadam; in each cubic meter of the high-performance concrete, the mass ratio of the cement to the antimony tailings macadam to the machine-made sand to the water reducing agent to the water is (442-485): (1047-1091): (724-758): (4.86-5.82): 160; the mineral component of the antimony tailings macadam is mainly quartz; and the content of SiO2 in the quartz is 74.47%-94.17%. According to the invention, the macadam prepared from the antimonytailings barren rock and cement are combined as the coarse aggregate to prepare the concrete, so that resource comprehensive recycling of the antimony tailings barren rock is realized, the stacking site and the management cost are reduced, the production cost of the concrete is reduced, and the concrete has the advantages of high strength, freezing resistance, crack resistance, impermeability, durability and the like.
本发明涉及一种基于锑尾矿废石的高性能混凝土及其制备方法，包括以下物料：粗骨料、机制砂、减水剂和水；所述粗骨料包括水泥和锑尾矿碎石；每立方米高性能混凝土中，各物料的质量比为水泥：锑尾矿碎石：机制砂：减水剂：水＝442～485：1047～1091：724～758：4.86～5.82：160；锑尾矿碎石的矿物成分主要为石英；石英中SiO2含量74.47％～94.17％。本发明利用锑尾矿废石制成的碎石和水泥结合作为粗骨料制成混凝土，实现锑尾矿废石的资源化综合回收利用，减少堆放场地和管理成本，降低混凝土的生产成本，且混凝土具有强度高、抗冻性、抗裂性、抗渗性与耐久性好等优点。
