MasterRoc MF 308

High-performance admixture for improved homogeneity, pumpability and placeability

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 uses:

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
