And it can also be seen that the clinker-free cemented iron tailings backfill material made of WGGBS-HPG-CS and iron tailings, each cubic meter of backfill material can absorb iron tailings up to 1565.834 kg/m 3. Therefore, the actual carbon emissions of using the clinker-free cemented iron tailings backfill material would be lower.
