BACKFILL MATERIAL
A backfill material useful in mining and tunneling applications comprises a) tailings, b) a binder component, c) water, and d) a dispersant comprising a phosphorylated polycondensate being obtainable by a condensation reaction of (i) an aromatic compound having a phosphate moiety, (ii) an alkoxylated hydroxyaryl compound having a polyoxyalkylene chain with 3 to 130 oxyalkylene units, and (iii) formaldehyde, in a weight ratio of (i) : (ii) of 2 : 98 to 40 : 60. The backfill material, besides a well-defined yield point, maintains a high Unconfined Compressive Strength in the long term so that the strength of the formed backfill is not compromised.
