Fly Ash/Blast Furnace Slag-Based Geopolymer as a Potential Binder for Mine Backfilling: Effect of Binder Type and Activator Concentration
This article investigated the potential of fly ash (FA)/blast furnace slag- (BFS-) based geopolymer as Gas Valve Coil a novel backfilling material.The effects of NaOH concentration and FA/BFS mass ratio were explored through XRD, FTIR, and TG-DTG analyses.The results indicated that the reaction products and strengths of geopolymer depended on the N
