Method for preparing mineral concrete recycled admixture from graphite tailings
The invention discloses a method for preparing a mineral concrete recycled admixture from graphite tailings. The invention relates to the technical field of composite materials, in particular to a process method for preparing a regenerated admixture, which is formed by mixing calcined concrete powder and graphite tailing powder, and comprises the following steps: firstly, crushing waste concrete and graphite tailings to remove impurities such as reinforcing steel bars in the waste concrete and magnetic components and active metal oxides in the graphite tailings, thereby avoiding later corrosion of the regenerated admixture. According to the invention, waste building materials and graphite tailings are utilized, the material preparation is simple, the manufacturing cost is low, the production process is simple, mineral admixtures such as fly ash, mineral powder and the like can be replaced, the cement consumption during concrete preparation is reduced, and the building cost is saved.
本发明公开了一种由石墨尾矿制备矿物混凝土再生掺和料的方法，涉及复合材料技术领域，该工艺方法以煅烧混凝土粉和石墨尾矿粉混合而成，首先对废弃的混凝土和石墨尾矿进行粉碎处理，去除废弃的混凝土中的钢筋等杂物和石墨尾矿中的磁性组分和活泼金属氧化物，避免再生掺和料出现后期锈蚀。本发明利用了废弃建材和石墨尾矿，配料简单，制造成本低，生产过程简易，能够取代粉煤灰、矿粉等矿物掺和料，降低配置混凝土时的水泥用量，节约建筑成本。
