摘　　要：本试验采用粉磨再混合的方式,利用正交试验方法,研究了废石膏、铜矿尾砂、混凝污泥及粉煤灰的不同组合对复合水泥物理性能的影响,在组分为粉煤灰14.05%、废石膏2.24%、混凝污泥22.47%、铜矿尾砂11.24%以及普通水泥50%获得复合水泥,28天后的抗折强度、抗压强度分别为28.30MPa和50.21MP。利用工业废料生产复合水泥,可就地取材,降低成本,同时解决了废渣料的贮存难问题,对保护环境有重要意义。In this paper,orthogonal experiments were conducted with materials re-mixed after grinding.A kind of blended cement was prepared with waste gypsum,copper tailings,coagulated sludge and fly ash.The influence of different mixed proportions on the physical properties of the cement was studied.The results showed that,the blended cement,prepared with 14.05% fly ash,2.24% waste gypsum,22.47% coagulated sludge,11.24% copper mine tailings and 50% of ordinary cement,has the bending strength of 28.30MPa and the compressive strength of 50.21MP after 28 days of storage.Using industrial waste for the production of composite cement can reduce cost while solving the storage problem of waste material,and is important for the environment protection.
