MasterRoc MF 308: High-performance admixture for improved homogeneity, pumpability and placeability of low-cohesion mine backfill mixes

Formerly: MEYCO MF 308

 

How does MasterRoc MF 308 work?

MasterRoc MF 308 admixture is an aqueous solution of a high-molecular weight synthetic copolymer formulated to improve the rheological behavior and in-situ properties of placed backfill. MasterRoc MF 308 admixture offers superior stability by increasing resistance to segregation, while acting as a pumping aid and facilitating placement with significant improvement in the homogeneity of the placed fill.

Recommended for use in:

  • All types of hydraulic, low density paste fills and cemented aggregate fills
  • Paste/hydraulic fills with lower solids content and/ or poor gradation
  • Segregation-prone fills like cemented hydraulic and aggregate fills

What are the unique features of MasterRoc MF 308?

  • Improves rheological behavior in low- to high-density slurries as well as in cemented aggregate fills
  • Improves cohesion and captivation of fines and binder inside the fill mass
  • Lubricates the fill
  • Acts as a pumping aid
  • Improves flow characteristics
  • Enhances robustness of the fill

What are the benefits of MasterRoc MF 308?

  • Enhances pumping and self-leveling of the fill
  • Reduces segregation
  • Facilitates production of highly fluid paste and more coherent and homogenous cemented aggregate fills
  • Provides stability during transportation and placement
  • Improves plastic behavior and lowers porosity of the fill
  • Increases compressive strengths
  • Reduces slime in the slump
  • Reduces water addition requirements
  • Improves reliability of fill delivery and increased production
  • Permits mix optimization and/or cost savings due to binder reduction (cement/slag cement/fly ash)
  • Makes mixes less sensitive to solid content variation and/or water demand
  • Improves mechanical properties of self-leveling fluid, making in-situ properties more consistent
  • Improves flow characteristics resulting in less wear and tear on pumps and pipes, thus extending equipment service life
  • Does not affect setting times within the recommended dosage rate
