Preparation method of high-strength coal gangue porous brick
The invention provides a preparation method of a high-strength coal gangue porous brick. The preparation method comprises the following steps: S1, preparing first mixed powder; S2, preparing second mixed powder; S3, preparing straw powder; S4, mixing the first mixed powder, the second mixed powder and the straw powder, and adding a proper amount of water and a dispersing agent; stirring to obtainaggregate; S5, performing pressure forming and performing pressure maintaining; S6, sintering; S7, steam curing; S8, taking out the brick subjected to steam curing, placing the brick in room temperature environment, and taking measures of sprinkling water and keeping moisture at room temperature for natural maintenance for 28 days. The porous brick fired by the method takes coal gangue as a main material and is reasonable in formula and has the characteristics of reasonable process design, simplicity in operation, energy conservation, comprehensive utilization of wastes and the like and is compact in structural combination and high in strength after being crushed for many times.
本发明提出了一种高强度煤矸石多孔砖的制备方法，包括如下步骤：S1：制备第一混合粉料；S2：制备第二混合粉料；S3：制备秸秆粉末；S4：将第一混合粉料、第二混合粉料与秸秆粉末混合，加入适量水和分散剂；搅拌，得到骨料；S5：加压成型，并保压；S6：烧结；S7：蒸养；S8：将经蒸气养护过的砖取出，放置室温环境，采取洒水常温保湿措施进行自然养护28天，采用本发明烧制的多孔砖以煤矸石为主料，配方合理，具有工艺设计合理、操作简单、节省能源、废物综合利用等特点，经多次粉碎，其结构结合紧密，强度高。
