摘要：Tailings' use is an important environment program and also society subject. Iron tailing is an environmental pollution resources, but it can be used to produce autoclaved aerated concrete (AAC). The chemical composition of iron tailing and the mineral compositions were analyzed by XRD test. The content of radioactive substance in iron tailing was also tested. The testing results show that the iron tailing meet the requirment for AAC production. Iron tailing was sieved to analyze the gradation and was milled by the ball grinding mill machine to proper fineness. Based on the given material mixing ratio, sample test showed that the density of AAC varies from 438 to 629 kg m(-3) with different finenesses of iron tailing, and the height ratio of final height to casting height of AAC changes with the finenesses of iron tailing. The research findings have important lessons for the production of aerated concrete with tailing.
