MasterRoc MF 501

​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 uses:

• 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​
