Unfired ceramsite with sodium silicate-bonded sand dust and carbide slag as excitants and preparation of unfired ceramsite
The invention discloses unfired ceramsite with sodium silicate-bonded sand dust and carbide slag as excitants and preparation of the unfired ceramsite, and belongs to the technical field of solid waste and hazardous waste resource recycling. The unfired ceramsite disclosed by the invention comprises the following components: 10%-50% of sodium silicate sand dust, 4%-15% of carbide slag and the balance of a material with volcanic ash activity. The preparation method comprises the following steps: ball-milling the sodium silicate sand dust and the dried carbide slag together, mixing the ball-milled powder with the fly ash, the mineral powder, the red mud and other materials with volcanic ash activity, uniformly stirring to obtain mixed powder, then carrying out ball rolling molding by using a ball rolling machine to prepare a ceramsite blank, and standing and curing to obtain the medium-high strength unfired ceramsite with good performance. According to the invention, the sodium silicate sand dust and the carbide slag are used as excitants to replace an alkali activator which is high in price and used in the traditional unfired ceramsite, so that the preparation cost of the unfired ceramsite is greatly reduced, and the unfired ceramsite with relatively high economic benefits is obtained.
本发明公开了属于固废、危废物资源回收利用技术领域的以水玻璃砂粉尘和电石渣为激发剂的免烧陶粒及其制备。本发明公布的免烧陶粒，包含以下组分：水玻璃砂粉尘10％‑50％，电石渣4％‑15％，余量为具有火山灰活性的材料。制备方法为：将水玻璃砂粉尘与烘干的电石渣一起球磨，球磨后与粉煤灰、矿粉、赤泥等具备火山灰活性的材料混合，搅拌均匀成为混合粉料，然后利用滚球机滚球成型制备陶粒胚体，静置养护后得到性能良好的中高强免烧陶粒。本发明利用水玻璃砂粉尘和电石渣为激发剂，替代了传统免烧陶粒使用的价格高昂的碱激发剂，极大地降低了免烧陶粒的制备成本，获得了较高经济收益的免烧陶粒。
