Utilization of coal gangue for the production of brick

Jun 08, 2016· Coal gangue, an industrial solid waste discarded from coal mining and processing, was used as the sole raw material to prepare brick. The coal gangue was crushed, homogenized, milled and then pressed into green compacts. The dried compacts were sintered at different temperatures for 2 h. The obtained brick samples were characterized with X-ray diffraction, scanning electron microscopy,
