Preparation method of low-calorific-value coal gangue unfired high-strength clay antique black brick
The invention relates to the field of building material preparation and solid waste resource utilization, in particular to a preparation method of a low-calorific-value coal gangue unfired high-strength clay antique black brick. Comprising the following steps: grinding clay to a preset particle size by using a grinding machine in advance for later use; then the coal gangue is dried in a preset temperature environment, so that the water content of the coal gangue is reduced to a preset water content; then the treated clay, coal gangue, cement, a coal gangue curing agent, an alkali inhibitor, a polycarboxylic acid type clay adsorbent and water are stirred and mixed uniformly according to a preset proportion, the mixture is put into a brick mold, and one-time compression molding is performed under preset pressure, so that the problem of resource utilization of a large amount of solid waste coal gangue is solved; the problem of alkali efflorescence in the using process of the coal gangue is solved, the problem that the coal gangue is prone to weathering is effectively reduced, the burning-free technology is adopted when the archaized black brick is manufactured through the method, fire coal consumption is avoided, energy consumption is reduced, and environmental pollution caused by waste gas emission due to insufficient coal combustion is avoided.
本发明涉及建筑材料制备和固体废弃物资源化利用领域，具体涉及一种低热值煤矸石免烧高强粘土仿古青砖的制备方法。包括以下步骤，预先将粘土用研磨机研磨到预设粒径后备用；然后将煤矸石在预设温度环境中进行烘干，使其含水量减少至预设含水量；接着将处理过的粘土、煤矸石、水泥、煤矸石固化剂、抑碱剂、聚羧酸型粘土吸附剂、水搅拌按照预设比例混合均匀后装入砖模具中，用预设压力一次压制成型，解决了大宗固体废弃物煤矸石的资源化利用问题，解决了煤矸石使用过程中的返碱问题，有效降低了煤矸石易风化的问题，且本发明方法制造仿古青砖时采用免烧工艺，避免对燃煤消耗，减小能源消耗，避免因煤燃烧不充分导致废气排放造成环境污染。
