Study on Production of Burning-Free Brick Using Chinese Kuancheng Iron Ore Tailings

Abstract:

Based on the analysis of components of Chinese Kuancheng iron ore tailings, burning-free brick test block were produced using local iron ore tailings and blast furnace slag as raw material, portlant cement as mineral glue, and parget as mineral activator. The optimum formula and production process were obtained with experiment of compressive strength of test blocks. The optimum ratio of iron ore tailing to blast furnace slag is between 5:5 and 6:4, parget composition is between 6% and 8%, and cement usage can be reduced to 10%. After curing, burning-free brick compressive strength of 17.5Mpa can be reached without sandiness phenomenon, and performance far exceeds the M10 burning-free brick standards. The formula of burning-free brick proposed in this paper can solve the problem of mineral waste pollution in Kuancheng area
