Electrolytic manganese residue shell-core type aggregate suitable for internal curing and preparation method of electrolytic manganese residue shell-core type aggregate
The invention discloses an electrolytic manganese residue shell-core aggregate suitable for internal curing and a preparation method thereof. The shell-core aggregate comprises the following components in parts by mass: an inner core: 30-50 parts of electrolytic manganese residue, 8-20 parts of blast furnace slag, 8-20 parts of carbide slag, 8-20 parts of cement and 15-30 parts of water; and the shell comprises 30-50 parts of cement and 8-15 parts of water. The carbide slag, the blast furnace slag and the cement are used for cooperatively treating the electrolytic manganese slag, and the purpose of treating waste with waste is achieved; holes are formed after CO2 and NH3 generated in the treatment process escape, so that the density of the aggregate is reduced, and meanwhile, the internal curing performance is improved; in addition, the cement shell serves as a barrier, migration of pollutant heavy metal is effectively inhibited, and the overall environmental protection effect is further improved. The method can realize comprehensive utilization of the electrolytic manganese residues, has the advantages of simple preparation process, lightweight and high strength of the aggregate, low cost, low carbon and environmental protection in production, and excellent internal curing performance, and has good application prospects.
本发明公开了一种适用于内养护的电解锰渣壳核型骨料及其制备方法，所述壳核型骨料包括质量份数如下的组分：内核为30‑50份电解锰渣、8‑20份高炉矿渣、8‑20份电石渣、8‑20份水泥和15‑30份水；外壳为30‑50份水泥和8‑15份水。本发明利用电石渣、高炉矿渣和水泥协同处理电解锰渣，实现了“以废治废”；在处理过程中产生的CO2和NH3气体逸出后形成孔洞，降低了骨料的密度，同时提高了内养护性能；此外，水泥外壳作为一道屏障，有效抑制了污染物重金属的迁移，进一步提升了整体环保效果。本发明可实现电解锰渣的综合利用，具有制备工艺简单、骨料轻质高强、成本低、生产低碳环保、内养护性能优良优点，具有良好的应用前景。
