Brick making process based on gneiss tailings

According to the brick making technology based on the gneiss tailings, the gneiss tailings are used as raw materials to prepare sintered bricks, reduction of the gneiss tailings can be achieved, meanwhile, secondary utilization of waste is achieved to the maximum extent, and an effective way is provided for resource utilization of the gneiss tailings; and huge pressure faced by economic construction and ecological environment in China is effectively relieved. On the basis of adopting gneiss tailings as a raw material, a brick making process is optimized, and the prepared brick has the characteristics of heat resistance, heat insulation, flame retardance, firmness and durability. 本发明提供一种基于片麻岩尾矿的制砖工艺，利用片麻岩尾矿作为原料制备烧结砖，既可实现片麻岩尾矿的减量化，同时还最大限度的地实现了废弃物的二次利用，为片麻岩尾矿的资源化利用提供了一条有效的途径，有效缓解我国经济建设以及生态环境所面临的巨大压力。本发明在采用片麻岩尾矿作为原料的基础上，优化制砖工艺，制备出来的砖具耐热、隔热、阻燃，以及坚固耐用的特点。
