摘　　要：实验以煤矸石为主要原料,探究并确定煤矸石的粒度、成型压力对煤矸石砖的影响,确定最佳的煤矸石粒度和成型压力。实验结果表明:成型压力不变,烧结温度为1 000℃时,随着煤矸石粒度增大,样品吸水率增大,抗压强度和密度减小。煤矸石粒度、烧结温度不变时,随着成型压力增大,样品吸水率减小,抗压强度和密度增大。This experiment with gangue as the main raw material to explore and determine me granularity of gangue, the influence of molding pressure on gangue bricks. Determine the best coal gangue granularity and molding pressure. The experimental show that when the forming pressure as constant and sintering temperature at 1 000℃, the sample water absorption increased, and compressive strength and density decreases with gangue granularity increased. When gangue granularity is constant and sintering temperature is 1 000℃, with the increase of the forming pressure, sample water absorption reduced, compressive strength and density increased.
