Method for improving freezing resistance of hollow bricks prepared from coal gangue raw materials
The invention relates to the technical field of preparation of novel building materials and discloses a method for improving freezing resistance of hollow bricks prepared from coal gangue raw materials. By pretreating coal gangue, regulating and controlling the proportion of dopants and adding and using a regulator, the uniformity of the temperature of a green brick roasting space is guaranteed, the firing shrinkage rate is reduced, and cooling cracks are prevented from being generated. According to the invention, the raw material price and the energy-saving advantage of the coal gangue are fully exerted, and the product with stable anti-freezing performance is prepared. Coal gangue is used as a main preparation raw material; iron tailings and fly ash solid wastes are used as auxiliary materials; by adding the prepared regulator, the blank roasting sensitivity is reduced, the green brick quality is optimized, the effects of prolonging the roasting zone, reducing the roasting rate and the roasting temperature, inhibiting the generation of expansion stress and preventing the green brick from disintegration and cracking are achieved, and the prepared hollow brick has the characteristics of good frost resistance, acid resistance, alkali resistance and the like, light weight and high strength.
本发明涉及新型建筑材料制备技术领域，公开了一种提高煤矸石原料制备空心砖的抗冻性的方法，通过对煤矸石预处理、掺杂物的配比调控以及调整剂的添加使用，保证了砖坯焙烧空间温度的均匀性，降低了烧成收缩率，防止冷却裂纹的产生；本发明充分发挥了煤矸石的原料价格和节能优势，制备得到抗冻性能稳定的产品。以煤矸石为主要制备原料，辅以铁尾矿、粉煤灰固体废弃物，添加制备的调整剂，降低坯料焙烧敏感性，优化砖坯质量，起到延长焙烧带，降低焙烧速率和焙烧温度的效果，抑制膨胀应力的产生，防止砖坯崩解开裂，制备得到的空心砖在抗冻、耐酸、耐碱等性能上表现均好，具有质轻、强度高的特点。
