摘要
这是一篇矿物材料领域的论文.以铁尾矿和粉煤灰为主要原料制备免烧陶粒,并研究了不同配比实验条件下铁尾矿掺量对制得免烧陶粒的堆积密度、表观密度、吸水率、强度的影响,结果表明:随着铁尾矿掺量的增加,陶粒的堆积密度和表观密度逐渐增大,吸水率逐渐减小,强度呈现先减小后增加的趋势.通过铁尾矿制备成陶粒的方式可以大幅提高铁尾矿利用率,所制得的免烧陶粒具有实际生产应用价值,可为铁尾矿固体废弃物资源的综合化利用提供新途径,有较好的经济效益和环保效益.
Abstract
This is an article in the field of mineral materials.Non-sintered ceramsite were prepared using iron tailings and fly ash as the main raw materials,and the effects of iron tailings proportion on the stacking density,apparent density,water absorption,and strength of non-sintered ceramsite were studied at different material mix ratio.The results showed that with the increase of iron tailings proportion,the stacking and apparent density of ceramsite gradually increased,while the water absorption gradually decreased.The strength shows a trend of decreasing first and then increasing.The method of preparing ceramsite from iron tailings can significantly improve the utilization rate of iron tailings.The non-sintered ceramsite production have practical application value and can provide a new way for the comprehensive utilization of iron tailings with good economic and environmental benefits.
