Preparation method of coal gangue archaized black brick
The invention discloses a preparation method of a coal gangue archaized black brick. The method comprises the following steps of: (1) material preparation: weighing the following materials by weight:20-40 parts of coal gangue, 20-40 parts of shale powder, 10-15 parts of quick lime, 15-25 parts of construction waste, 5-13 parts of green ash, 2-5 parts of carbon powder, 3-10 parts of water glass, 2-5 parts of a water repellent agent and 2-5 parts of an anti-freezing agent; (2) raw material pretreatment: ball-milling the raw materials to a particle size of less than 2 microns; (3) material mixing: controlling the moisture content of the mixture to be 15-20%; (4) molding: extruding the mixture, and performing cutting into green bricks with composite specifications; (5) firing; and (6) curing:soaking the fired green bricks in a quartz sand aqueous solution, and performing natural curing for 20-30 days. The prepared archaized black brick is attractive in appearance and compact in interior,has good freezing resistance, durability, corrosion resistance and pressure resistance, is not prone to cracking, peeling and falling off after being used, and is high in product strength.
本发明公开了的一种煤矸石仿古青砖的制备方法,包括以下步骤:①备料:按照以下重量份数称取物料:煤矸石20～40份、页岩粉20～40份、生石灰10～15份、建筑垃圾15～25份、青灰5～13份、碳粉2～5份、水玻璃3～10份、疏水剂2～5份和防冻剂2～5份；②原料预处理：将各球磨至各原料的粒径小于2um；③混料：混合料的含水率控制在15～20%之间；④成型：将混合料挤压、切割成复合规格的砖坯；⑤烧制；⑥养护：将烧制后的砖坯浸泡在石英砂水溶液中自然养护20～30天。本发明制得的仿古青砖外表美观，内部密实，具有很好的抗冻性、耐久性、耐腐蚀性和抗压性，使用后不易产生开裂、起皮、脱落的现象，产品强度高。
