The invention discloses a method for producing aerated concrete blocks from iron tailings and waste granite. The method comprises the steps of (1) preparing the following raw materials in percentage by mass: 20-50% of iron tailings, 20-50% of waste granite, 5-25% of cement, 0.5-2% of lime, 1-5% of titanium gypsum and 0.05-0.1% of aluminum powder paste; (2) stirring and mixing the iron tailings, the waste granite, the cement, the lime, the titanium gypsum and the aluminum powder paste to obtain a mixture, and stirring and mixing the mixture and the water phase to obtain slurry; and (3) pouringthe slurry into a mold, standing to form a green body, and carrying out autoclaved curing after the cutting strength is reached, thereby obtaining a ceramic tile-like product. The method is simple inprocess and easy to implement, the iron tailings and the waste granite can be recycled, the aerated concrete blocks can be stably regenerated, and the purposes of environmental protection and resourcerecycling are achieved.
本发明公开了一种铁尾矿和废弃花岗岩生产加气混凝土砌块方法，其包括以下步骤：(1)预备以下质量百分比原料：铁尾矿20～50％、废弃花岗岩20～50％、水泥5～25％、白灰0.5～2％、钛石膏1～5％和铝粉膏0.05～0.1％；(2)将铁尾矿、废弃花岗岩、水泥、白灰、钛石膏和铝粉膏相搅拌混合获得混合料，将混合料和水相搅拌混合获得料浆；(3)将料浆倒入模具，然后静置形成坯体并且达到切割强度后，进行蒸压养护，制成的仿瓷砖制品。本发明工艺简易，易于实现，能对铁尾矿和废弃花岗岩进行回收稳定再生加气混凝土砌块，达到了保护环境，资源再生利用的目的。
