Steaming-free and baking-free brick and preparation method thereof
The invention provides a steaming-free and baking-free brick and a preparation method thereof, and belongs to the technical field of building materials. According to the method, reduction and recycling of the natural gas water-based drilling solid waste are realized; coal ash is fine ash in smoke generated after coal combustion, a large amount of cement and fine aggregate are saved by doping the coal ash, the water consumption is reduced, the workability of a mixed slurry is improved, the pumpability of the mixed slurry is enhanced, creep of the mixed slurry is reduced, hydration heat and heatenergy expansibility are reduced, and the impermeability of the steaming-free and baking-free brick is improved. The modifiability of the steaming-free and baking-free brick is improved; the cement is used as a cementing material, is powdery, and is mixed with a proper amount of water to form plastic slurry, the slurry can be changed into hard stone-like bodies through a physical and chemical process, the granular material can be cemented into a whole, and the cement can be better hardened in water to maintain and develop the strength; the desulfurized gypsum is used as a sulfate activator, plays a role of an accelerant, and can directly and indirectly enhance the strength of the steaming-free and baking-free brick.
本发明提供了一种免蒸免烧砖及其制备方法，属于建筑材料技术领域。本发明实现了天然气水基钻井固废的减量化资源化；粉煤灰是从煤燃烧后烟气中的细灰，掺加粉煤灰节约了大量的水泥和细骨料，减少了用水量，改善了混合浆料的和易性，增强混合浆料的可泵性，减少了混混合浆料的徐变，减少水化热、热能膨胀性，提高免蒸免烧砖抗渗能力，增加免蒸免烧砖的修饰性；水泥作为胶凝材料，其呈粉末状，与适量水拌合成塑性浆体，经过物理化学过程浆体能变成坚硬的石状体，并能将散粒状材料胶结成为整体，还能更好地在水中硬化，保持并发展强度；脱硫石膏作为硫酸盐激发剂，起到促进剂的作用，能直接和间接增强免蒸免烧砖的强度。
