Paper Title:
Preparation and its Application Performance of Backfilling Cementation Material Based on Blast Furnace Slag
  Abstract

The blast-furnace slag (BFS)has been characterized by chemical and phase composition to evaluate its hydration reactivity. It has high potential activity for its glassy structure, so its use to prepare new filling cementation material is possible. New backfilling cementation material composition has been formulated and optimized by activation of BFS. The optimal formula of new backfilling cementation material SL(Slag activated by lime) and SLG(Slag activated by lime and desulfurization gypsum) was 87% BFS, 13% lime and 78.4% BFS, 11.8% lime, 9.8% desulfurization gypsum respectively. Finally, the feature of application performance was analyzed through comparison between new cementation material and ordinary Portland cement with paste and sand mortar experiment. The result showed that material SL and SLG have superior performance to ordinary Portland cement used to mining cemented filling.
