MasterRoc MF 901

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?

• Reduces 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)

• Enhances 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
