    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

    • 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
