All-solid waste cementing material as well as preparation method and application thereof
The invention provides an all-solid waste cementing material as well as a preparation method and application thereof. The cementing material comprises the following components in parts by mass: 30-70 parts of fluidized bed combustion ash, 10-35 parts of an active component, 0-14 parts of carbide slag, 0-30 parts of fine coal gangue and 0-6 parts of desulfurized fly ash, wherein the active component comprises at least one of fly ash, slag powder, steel slag powder and red mud, and the particle size of the fine coal gangue is not greater than 0.6 mm. When the cementing material is applied to the coal gangue-based filling paste, the coal gangue-based filling paste which is good in curing performance, low in price and good in filling performance can be obtained.
本发明提供一种全固废胶凝材料及其制备方法和应用，胶凝材料按照质量份数包括以下组分：固硫灰30～70份、活性组分10～35份、电石渣0～14份、细煤矸石0～30份、脱硫灰0～6份；其中，所述活性组分包括粉煤灰、矿渣粉、钢渣粉、赤泥中的至少一种，所述细煤矸石的粒径不大于0.6mm。将该胶凝材料应用于煤矸石基充填膏体中，有利于得到固化性能好、价格低廉、充填性能好的煤矸石基充填膏体。
