MasterRoc MF 903

High Performance Dispersing Admixture for Mine Backfill Mixes

How Does MasterRoc MF 903 Work?

MasterRoc MF 903 is a liquid, dispersing admixture used to enhance backfill properties.

Areas of Application

• Paste fill

• High density fill

• Cemented rockfill

• Hydraulic fill

What Are the Benefits of MasterRoc MF 903?

• Reduces the water content of backfill materials leading to higher in-situ strengths

• 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
