Ec0star is a propriety blended cementitious material designed to be blended with mine tailings to achieve stable backfill.

Ec0star is a typically used in backfill operations to achieve a stable backfill product in a weep or non-weep system.

Further benefits are:

  • Ability to set and strengthen in low waterflow.
  • Low bleeding.
  • Good flowability and pumpability for long durations.
  • Low pump pressures.
  • Low carbon footprint.
  • Increase production achievable with the same labour force and equipment.
  • Strengths of 5.7MPa achieved for 28 days using 8% binder.
  • Product complies with 32.5 specification when tested as per SANS 50197.
  • Efficiency % per ton of backfill placed is currently 80%.
  • A 100% efficiency of backfill placed can be achieved in the phase 2 of the product.
  • Currently 15% more gained backfill volume underground compared to conventional backfill binders.
  • Ec0star is a 100% locally manufactured product.
  • The flow rate is approximately 6.9 seconds.

Ec0star increases fluidity and lubrication in underground pipeline systems.

The flow rate of Ec0star is approximately 6.9 seconds.

Ec0star should not be used in an unventilated environment.
