Method for preparing wet-mixed mortar by utilizing waste residue nickel slag
The invention discloses a method for preparing wet-mixed mortar by utilizing waste residue nickel slag. Waste residue nickel slag discharged by nickel product production enterprises passes through a 20-mesh mechanical sieve, and 100% by weight of a nickel slag product with the water content of 25% and 5-15% by weight of 325 general cement are uniformly stirred together through a mixing stirrer toobtain wet-mixed mortar; the product can be widely applied to various material mortars for constructional engineering construction, and has the characteristics of high strength, small shrinkage rate,good frost resistance, firm bonding strength, good water retention capacity and the like; the wet-mixed mortar nickel slag prepared by the method has the advantages that the utilization rate reaches 100%, the additional value is high, natural sand resources are completely replaced, the water is saved by 25%, meanwhile, the cost of land stacking, landfilling and the like is saved, the ecological environment is protected from secondary pollution and damage, and a new technical method is provided for waste slag nickel slag discharged by the nickel product production enterprises.
本发明公开了一种利用废渣镍渣制备湿混砂浆的方法，采用生产镍产品企业排出的废渣镍渣，通过20目机械筛余，将含水量为25%的镍渣产品按重量百分比计为100%，与325通用水泥按重量百分比计为5‑15%，一起经混合搅拌机搅拌均匀即得湿混砂浆；该产品可广泛用于各种建筑工程建设的用料砂浆，具有强度高、收缩率小、抗冻性好、粘结强度牢、保水性能好等特点；本发明制得的湿混砂浆镍渣利用达100%，附加值高，100%替代了天然砂资源，节水25%，同时又节约了土地堆放和填埋等费用，保护了生态环境不受二次污染和破坏，为生产镍产品企业排出的废渣镍渣提供了一种新的技术方法。
