Superfine tailing cemented filling soft soil curing agent and preparation method and application thereof
The invention discloses a superfine tailing cemented filling soft soil curing agent as well as preparation and application thereof. The superfine tailing cemented filling soft soil curing agent is prepared from 41-56 wt% of mineral powder, 10-11 wt% of steel slag powder, 20-35 wt% of gypsum powder, 9-11 wt% of an alkaline activator and 1-3 wt% of an activating agent. The soft soil curing agent is used for superfine tailing cemented filling, filling can be performed under the conditions of lower cement-sand ratio and high slurry concentration, better slurry flowing performance and consolidated body strength performance can be kept, main raw materials of the soft soil curing agent are bulk industrial solid waste, a large amount of solid waste can be consumed, resource utilization of a large amount of industrial solid waste is achieved, and the problems that the cement-sand ratio is large, the fluidity is poor, the cost is high, and the strength of a filling body is low in superfine tailing cemented filling are solved.
本发明公开了一种超细尾砂胶结充填软土固化剂及其制备和应用，由41～56wt％的矿粉、10～11wt％的钢渣粉、20～35wt％的石膏粉、9～11wt％的碱性激发剂和1～3wt％的活化剂制得。本发明的软土固化剂用于超细尾砂胶结充填，可在较低灰砂比，高浆体浓度下保持较好的浆体流动性能和固结体的强度性能进行充填，所述软土固化剂的主要原料均为大宗工业固体废物，不仅可以大量消纳固体废物，实现大宗工业固废的资源化利用，还解决了超细尾砂胶结充填存在的灰砂比大、流动性差、成本高以及充填体强度低等问题。
