Utilization of coal gangue for the production of brick ...

2016-6-8  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, and ...

At stage B, as the stress gradually rose, a great number of particles were crushed and crushed small particles filled in pores. Therefore, the porosity of broken coal and rock masses reduced and the resistance of broken coal and rock masses to structural deformation gradually increased. Thus, the increase rate of strain gradually declined.
