Strength development and microstructural investigation of lead-zinc mill tailings based paste backfill with fly ash as alternative binder

The increasing popularity of paste backfilling demands alternative binder optimisation and bulk waste disposal. This study investigates the efficacy of fly ash (FA) as partial replacement of ordinary portland cement (OPC) for paste backfill application in underground mines. The effect of FA addition...
