​MasterRoc MF 501 - High-performance plasticizing and water-reducing admixture for mine backfill mixes


How does MasterRoc MF 501 work?

MasterRoc MF 501 admixture is a liquid, water reducing admixture used to enhance the properties of mine backfill.

Recommended for use in:

  • Paste fill
  • High-density fill
  • Cemented rock fill
  • Hydraulic fill

What are the unique features of MasterRoc MF 501?

  • Reduced water content
  • Improved slump and flow characteristics
  • Normal setting time and rate of hardening
  • Reduces pumping and distribution pressures

What are the benefits of MasterRoc MF 501?

  • Backfill optimization and/or cost savings by binder reduction (cement/slag cement/fly ash)
  • Enhances workability (rheological properties) in all types of backfills, requiring less water
  • Higher in-situ strengths at all ages
  • Reduces segregation of high-density slurries
  • Reduces permeability and shrinkage in hardened fill
  • Potentially reduces cycle time and increases production
