Method for preparing autoclaved sand-lime brick from multi-source solid waste containing lithium slag
According to the method, the pozzolanic activity of the multi-source solid waste such as the nickel-iron alloy slag, the lithium slag, the waste incineration fly ash, the waste stone powder, the desulfurization ash, the white mud, the coal gasification ash, the coconut shell, the shrub branches, the lake bottom mud, the sea sand and the waste water slurry is improved in the modes of mechanical activation, chemical activation and the like, and the pozzolanic activity of the solid waste is improved on the basis of cement concrete cementing material research. And preparing the all-solid waste autoclaved sand-lime brick. The strength grade of the brick meets the requirements of MU30 in autoclaved sand-lime solid bricks and solid building blocks GB/T 11945-2019 and autoclaved fly ash bricks JC/T 239-2014, the freezing resistance meets the index requirements of D50 in severe cold areas, in addition, the water absorption rate, the carbonization coefficient and the softening coefficient all meet the requirements of like products, the product quality is stable, and the production cost is effectively reduced.
本发明利用镍铁合金渣、锂渣、垃圾焚烧飞灰、废石粉、脱硫灰渣、白泥、煤气化灰渣、椰壳、灌木树枝、湖泊底泥、海砂、废水泥浆等多源固废，通过机械力活化和化学活化等方式，提升固废的火山灰活性，在水泥混凝土胶凝材料研究的基础上，制备全固废蒸压灰砂砖。其强度等级达到《蒸压灰砂实心砖和实心砌块》GB/T 11945‑2019和《蒸压粉煤灰砖》JC/T 239‑2014中MU30的要求，抗冻性达到严寒地区D50的指标要求，此外吸水率、碳化系数和软化系数均达到同类产品要求，产品质量稳定，生产成本有效降低。
