?MasterRoc MF 901

High performance plasticizing and water-reducing admixture for cementitious mine backfill.

How does MasterRoc MF 901 work?

MasterRoc MF 901 is a liquid, water- reducing admixture used to enhance backfill properties.

Recommended uses:

• Cemented paste fill
• Cemented high density hydraulic fill
• Cemented rock fill
• Cemented aggregate fill

What are the unique features of MasterRoc MF 901?

• Reduced water content of backfill materials for given slump
• Improves slump and flow properties (rheological properties)
• Increases in-place strength at all ages
• Normal setting time and hardening rate
• Reduces pumping and distribution pressures
• Quick wetting effect, high efficiency mixing, and higher flow rates
• Can be added at a higher than recommended dosage to achieve extended time of setting

What are the benefits of MasterRoc MF 901?

• Mix optimization and/or cost savings by reduction of binders (cement, slag cement, fly ash)
• Enhanced workability of the backfill materials, requiring less water
• Higher in-situ strengths of the backfill materials
• Potentially reduces the cycle time and increases production
• Reduces permeability and shrinkage in hardened backfill materials?
