MasterRoc MF 504

High-Performance Dispersing Admixture for Mine Backfill Mixes

How Does MasterRoc MF 504 Work?

MasterRoc MF 504 is a liquid, dispersing admixture used to enhance backfill properties.

Recommended Uses:

• Paste fill

• High-density fill

• Cemented rockfill

• Hydraulic fill

What Are the Unique Features of MasterRoc MF 504?

MasterRoc MF 504 reduces the water content of backfill materials, leading to higher in-situ strengths.

What Are the Benefits of MasterRoc MF 504?

• 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 optimisation and 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
