Preparation and application of tailing sand and artificial sand composite concrete
The invention discloses preparation and application of tailing sand and artificial sand composite concrete. The preparation method comprises the following steps: carrying out primary treatment on tailing sand and artificial sand by adopting a double-shear mixing device; sampling the raw materials treated by the double-shear mixing device, and respectively detecting the water absorption rates of the tailing sand and the artificial sand; according to the water absorption rate of the tailing sand and the artificial sand, the volume and mass of water, cement and other sizing materials needing to be added are calculated through a central control module; and adding and uniformly mixing the raw materials according to the addition amount calculated by the central control module by adopting a concrete stirring device according to the calculated result. According to the preparation method of the tailing sand and artificial sand composite concrete provided by the invention, the tailing sand and artificial sand composite concrete is synchronously sheared and mixed by adopting a double-shearing mixing device, so that the working efficiency is improved, meanwhile, the pollution of the tailing sand to the environment is reduced, the utilization rate of the tailing sand is increased, and the cost of a structural engineering building is reduced.
本发明公开了一种尾矿砂与人工砂复合混凝土的制备及应用，采用双剪切混料装置对尾矿砂和人工砂进行初处理；对通过双剪切混料装置处理后的原料进行取样并分别检测尾矿砂和人工砂的吸水率；根据尾矿砂和人工砂的吸水率，通过中控模块计算需要添加的水、水泥等胶料的体积、质量；根据计算出来的结果，采用混凝土搅拌装置将各原料按照中控模块计算出来的加入量加入并混匀。本发明提供一种尾矿砂与人工砂复合混凝土的制备方法，并采用双剪切混料装置对尾矿砂与人工砂复合混凝土进行同步剪切并混料，提高工作效率，同时降低尾矿砂对环境的污染，提供其利用率，降低结构工程建筑的成本。
