Embodiment
[0015] The brick making method of this embodiment includes the following steps:
[0016] 1) The following raw materials by volume are crushed and mixed to obtain brick-making raw materials: 30-40 parts of construction waste, 20-30 parts of shale, 10-15 parts of coal cinder and 50-80 parts of clay;
[0017] 2) Mix brick-making raw materials and sawdust at a volume ratio of 10:1 and then add water and stir to make mud. The sawdust is made by crushing straw, branches and leaves, and waste wood furniture, and then aged for more than 2 days;
[0018] 3) Use a vacuum brick extruder to make the mud into bricks, and place the bricks in the drying hole for concentrated moisture removal and drying;
[0019] 4) The bricks are fired under the condition of a vacuum degree of less than 0.1, and the firing temperature is 700-800°C to obtain finished bricks.
