Aerated concrete block produced from electrolytic manganese residues and preparation method of aerated concrete block
The invention discloses an aerated concrete block produced from electrolytic manganese residues and a preparation method of the aerated concrete block, and belongs to the technical field of solid waste resource utilization. The preparation method for producing the aerated concrete block from the electrolytic manganese residues comprises the following steps: removing ammonia nitrogen and manganese in the electrolytic manganese residues in a leaching manner through mechanical oscillation, then mixing the electrolytic manganese residues without the ammonia nitrogen and the manganese with the red mud, the cement, the fly ash, the sand, the lime, the gypsum and the aluminum powder according to the proportion of the formula, and performing extrusion molding to obtain the aerated concrete block. Stirring at a high speed under a fixed water-to-material ratio to form mixed slurry, pouring the mixed slurry into a mold, curing, and autoclaving to obtain the aerated concrete building block. All indexes of the aerated concrete prepared by the method can meet index requirements, and meanwhile, a practical and effective method is provided for solving the problem of resource utilization of the two solid wastes, namely the electrolytic manganese residues and the red mud.
本发明公开了一种电解锰渣生产加气混凝土砌块及其制备方法，属于固体废弃物资源化利用的技术领域。一种电解锰渣生产加气混凝土砌块的制备方法包括以下步骤：通过机械振荡以浸取的方式将电解锰渣中的氨氮和锰去除，随后将脱除氨氮和锰的电解锰渣与赤泥、水泥、粉煤灰、砂、石灰、石膏、铝粉按照上述配方比例混合后，在固定水料比下高速搅拌成混合料浆，并浇筑至模具中，养护后蒸压得到加气混凝砌块。本发明制备的加气混凝土各项指标均能达到指标要求，同时也为解决电解锰渣和赤泥这两种固体废弃物的资源化利用问题提供了切实有效的方法。
