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 backfill properties.

Recommended uses:

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

What are the unique features of MasterRoc MF 501?

MasterRoc MF 501 Reduces the water content of back fill materials leading to higher in-situ strengths

What are the benefits of MasterRoc MF 501?

  • Improves slump and flow properties
  • Increases in-place strength at all ages
  • Normal setting time and rate of hardening
  • Reduces pumping and distribution pressures
  • Mix 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
  • Reduces segregation of high density slurries
  • Reduces permeability and shrinkage in hardened fill
  • Potentially reduces cycle time and increases production
