In order to improve the resource utilization rate of copper tailings and building muck, the invention discloses a copper tailing and muck curing agent which is composed of the following components inpercentage by mass: 30%-40% of ferrovanadium slag, 30%-35% of slag powder, 15%-20% of slaked lime, 2%-4% of gypsum and 1%-16% of limestone powder. The curing agent disclosed by the invention is used for preparing a copper tailing or muck non-fired wall material; and the copper tailing or muck non-fired wall material is prepared by adding a proper amount of water into the copper tailing or muck curing agent, uniformly mixing the materials, molding the mixture and curing the mixture. According to the curing agent, industrial wastes such as the ferrovanadium slag, slag powder, desulfurized gypsumand limestone powder are taken as raw materials, the preparation process is simple, and the production cost is low. The non-fired wall material of copper tailings or muck prepared by utilizing the curing agent is high in compressive strength and good in durability. The preparation method and application of the copper tailing and muck curing agent have important significance in effective utilization of waste resources, environmental protection and building energy conservation.
为提高铜尾矿及建筑渣土的资源利用率，本发明公开了一种铜尾矿及渣土固化剂，由以下组分及质量分数组成：钒铁渣30％～40％，矿渣粉30％～35％，熟石灰15％～20％，石膏2％～4％，石灰石粉1％～16％。本发明的固化剂用于制备铜尾矿或渣土免烧墙体材料，将铜尾矿或渣土和固化剂加入适量水混合均匀，再成型、养护即制备成铜尾矿或渣土免烧墙体材料。该固化剂以钒铁渣、矿渣粉、脱硫石膏、石灰石粉这些工业废弃物为原材料，制备工艺简单，生产成本低。利用该固化剂制备的铜尾矿或渣土的免烧墙体材料抗压强度高，耐久性好。本发明对废弃资源的有效利用、保护环境和建筑节能具有重要意义。
