Backfill materialQueensMineDesignWiki

Ground granulated blast furnace slag (GGBFS) is a product of the iron and steel industry. Slag that is quenched rapidly forms amorphous silica i.e. material with a high glass content. High glass content and the right chemistry are key characteristics of slag cement. Mine tailings are desired in backfill only because they are generally

Autoclaved Brick from Steel Slag and Silicon Tailings

The load-bearing brick is made from steel slag and silicon tailings by pressing and autoclaving process. Because of the volume stability steel slag was ground to above 320 m2/kg and wet cured in 50-60°C at 12-24 hours in the present of additives before pressure forming and autoclaving process. Tailings account for 63 of the total mass of the brick while steel slag 30 .
