Method for preparing sintered brick from final aluminum ash
The invention discloses a method for preparing a sintered brick from final aluminum ash, and belongs to the technical field of environmental protection. The method comprises the steps: firstly, mixing final aluminum ash, engineering soil and coal gangue to obtain a brick making raw material, mixing the brick making raw material and a nitrogen removal additive, adding water, uniformly stirring, aging, taking out the aged raw material, putting into a mold, carrying out compression molding to obtain a green brick, and roasting to obtain the sintered brick. On one hand, the preparation process of a common sintered brick is simplified, and the same strength requirement can be met; on the other hand, the final aluminum ash serves as the raw material of the sintered brick, the engineering soil and the coal gangue are supplemented, and industrial waste and capital construction waste are comprehensively utilized.
本发明公开了一种铝灰终灰制备烧结砖的方法，属于环保技术领域。该方法是先将铝灰终灰、工程土、煤矸石混合得到制砖原料，然后将制砖原料和除氮添加剂混合后，加入水，搅拌均匀后进行陈化，陈化好后的原料取出，放入模具中压制成型，得到砖坯，经焙烧，得到烧结砖。本发明一方面简化了普通烧结砖的制备流程，并且可以满足同等的强度要求，另一方面本发明将铝灰终灰作为了烧结砖的原料，辅以工程土和煤矸石，将工业废弃物和基建废弃物综合利用。
