Abstract

There exist synergistic effect between steel slag and blast furnace slag in preparation of solidifying agent for total tailings backfill. By investigating the effect of various activators, the proportioning of the solidifying agent was obtained: steel slag 35 %, blast furnace slag 35 %, Portland cement 10%, desulfurization gypsum 10%, calcium chloride 6%, anhydrous sodium sulfate 2% and calcium oxide 2%. The results show that compressive strength of specimens reaches 2.83MPa, with the mass ratio of tailings and the solidifying agent being 1:5. It can be used to substitute Portland cement in total tailings backfill for goaf.
