Method for preparing hollow bricks from coal gangue
The invention relates to the technical field of preparation of novel building materials, and discloses a method for preparing a hollow brick from coal gangue, which ensures that the coal gangue is greatly utilized under the condition of ensuring the performance of the hollow brick by researching the plasticity of the coal gangue and controlling the conditions of the sintering process, and has thecharacteristics of low cost, low energy consumption and high yield. The raw material price and the energy-saving advantage of the coal gangue are fully achieved, so that the product with stable quality is prepared, the performance of the hollow brick prepared from the coal gangue is improved, and the using and adding amount of solid waste is increased. According to the invention, the coal gangue is used as a main preparation raw material with addition of modified fly ash, so that the blank roasting sensitivity is reduced, the green brick quality is optimized, the effect of adsorbing and fixingsulfur and carbon is achieved, generation of sulfur dioxide, hydrogen sulfide, carbon dioxide and other harmful gases is inhibited, green brick disintegration and cracking are prevented, and the prepared hollow brick is good in wear resistance, acid resistance, alkali resistance and other performances. In addition, the product has characteristics of light weight and high strength.
本发明涉及新型建筑材料制备技术领域,公开了一种利用煤矸石制备空心砖的方法,通过对煤矸石可塑性研究以及烧结过程的条件把控,保证了空心砖性能的情况下大幅利用煤矸石,具有低成本、低能耗、高产出的特点;本发明充分发挥了煤矸石的原料价格和节能优势,制备得到质量稳定的产品,改善了煤矸石制备空心砖的性能,提高了固体废料的使用添加量。以煤矸石为主要制备原料,添加改性粉煤灰,降低坯料焙烧敏感性,优化砖坯质量,起到吸附固定硫、碳的效果,抑制二氧化硫、硫化氢、二氧化碳等有害气体的产生,防止砖坯崩解开裂,制备得到的空心砖在耐磨、耐酸、耐碱等性能上表现均好,具有质轻、强度高的特点。
