Water glass excited nickel slag-household garbage incinerator slag-fly ash high-strength environment-friendly brick and preparation method thereof
The invention discloses a water glass excited nickel slag-household garbage incinerator slag-fly ash high-strength environment-friendly brick. The brick is prepared through the following steps: carrying out aluminum removal treatment on granular furnace slag by adopting a NaOH solution, pouring nickel slag, coal ash, powdery furnace slag and the aluminum-removed granular furnace slag into a mortarstirrer, stirring, adding water and water glass, stirring at a low speed for 90 s, stirring at a high speed for 120 s, pouring the obtained mixture into a mold, standing for 1 day, demolding, and curing in a standard curing room with the temperature of 20 +/-2 DEG C and the relative humidity of 95% or above for 28 days to obtain the high-strength environment-friendly brick. The high-strength environment-friendly brick is prepared by taking the nickel slag, the coal ash and the household garbage incineration slag as raw materials, the raw materials are rich in source and are changed into valuables from wastes, and the nickel slag, coal ash and household garbage incinerator slag are excited with sodium silicate with the proper modulus, so the prepared environment-friendly brick can reach the MU20 strength grade, and the environment-friendly brick has good economic, social and environment-friendly benefits and is suitable for large-scale application and popularization.
本发明公开了一种水玻璃激发的镍渣‑生活垃圾焚烧炉渣‑粉煤灰高强环保砖，其是采用NaOH溶液对颗粒状炉渣进行去铝处理，然后将镍渣、粉煤灰、粉状炉渣和去铝处理后的颗粒状炉渣倒入砂浆搅拌机中搅拌，再加入水和水玻璃，低速搅拌90s后高速搅拌120s，倒入模具中静置1天后拆模，再于20±2℃、相对湿度95%以上的标准养护室中养护28天，制得所述高强环保砖。本发明以镍渣、粉煤灰和生活垃圾焚烧炉渣作为原材料制备高强环保砖，其来源丰富，且能变废为宝，而且采用合适模数的水玻璃对镍渣、粉煤灰和生活垃圾焚烧炉渣进行激发，可使制得的环保砖达到MU20强度等级，其具有良好的经济、社会和环保效益，适合大规模推广应用。
