Sludge autoclaved brick and preparation method thereof
The invention discloses a sludge autoclaved brick and a preparation method thereof, and belongs to the technical field of solid waste treatment. The sludge autoclaved brick is prepared from the following raw materials in parts by weight: 50-80 parts of sludge, 0-10 parts of lime, 5-15 parts of blast furnace slag, 0-5 parts of alkaline residues, 0-20 parts of stone powder, 10-20 parts of electric furnace slag, 2-5 parts of desulfurized gypsum, 1-5 parts of silica fume, 0-10 parts of fly ash, 3-8 parts of cement, 0.5-0.01 part of a polycarboxylate superplasticizer, 0.1-0.01 part of an alkali activator and 8-12 parts of water. The steam-cured brick is prepared from the sludge, the stone powder, the electric furnace slag and the like, the solid waste consumption is large, the problem of solid waste accumulation can be solved, waste can be turned into wealth, and comprehensive utilization of resources is achieved; (2) a pressing steam-curing process is adopted for preparation, the process is simple, and production is convenient; (3) an unfired technology is adopted, so that atmospheric pollution is avoided, the effects of saving energy and reducing carbon can be achieved, and the ecological benefit is remarkable; and (4) the prepared autoclaved brick has the advantages of long service life, high strength and stable product performance, and production of autoclaved bricks with different specifications and sizes can be realized.
本发明公开了一种淤泥蒸压砖及其制备方法，属于固废处置技术领域。淤泥蒸压砖通过以下重量份计的原料制得：淤泥50～80份，石灰0～10份，高炉渣5～15份，碱渣0～5份，石粉0～20份，电炉渣10～20份，脱硫石膏2～5份，硅灰1～5份，粉煤灰0～10份，水泥3～8份，聚羧酸减水剂0.5～0.01份，碱激发剂0.1～0.01份，水8～12份。本发明(1)使用淤泥、石粉、电炉渣等制备蒸养砖，固废用量大，既可处理固废堆积问题，又可变废为宝，实现资源综合利用；(2)通过压制蒸养工艺制备，工艺简单，生产方便；(3)采用免烧技术，不会产生大气污染，还可起到节能降碳效果，生态效益显著；(4)所制备的蒸压砖具有寿命长、强度高、产品性能稳定的优点，并且可以实现不同规格尺寸蒸养砖的生产。
