　　Abstract：The developed sintered brick made from gangue and fly ash as industrial wastes as well as weathered shale as main raw materials has obviously social and economic benefits. This paper introduces performance of raw materials, formula composition, production process and product performance. It points out that the high pressure vacuum extruded forming process with selected glue can increase the dry strength of semi－product. The sintering temperature boostings of 50～80 ℃/h before 300 ℃ and 100 ℃/h after 300 ℃ are proper.
　　Keywords：gangue, fly ash, weathered shale, sintered brick
