Research on Cementing Performances of Environment-Friendly Backfilling Cementation Material Based on Blast Furnace Slag
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 SLC(Slag activated by lime and calcium chloride) was 87% BFS,13% lime and 86.84% BFS, 13.02% lime, 0.14% calcium chloride respectively. Finally, the feature of cementing properties was analyzed through comparison between new cementation material and ordinary Portland cement with compressive strength, water requirement of normal consistence, setting time, bleeding water and slump. The result showed that material SL and SLC have superior performance to ordinary Portland cement used to mining cemented filling.
