BACKFILL MATERIAL
A backfill material useful in mining and tunneling applications comprises a) tailings, b) a binder component, c) water, and d) at least one dispersant selected from polycarboxylate ethers and polycarboxylic acids. The binder component comprises a Portland cement clinker-based binder and calcined clay. By the partial substitution of Portland cement clinker-based binder by calcined clay, the backfill material has a reduced carbon footprint. The yield point of the material and the compressive strength of the formed backfill are not compromised.
