MasterRoc MF 705

High Performance Backfill Admixture

How Does MasterRoc MF 705 Work?

MasterRoc MF 705 is a ready-to-use, non-chloride liquid admixture used for making more uniform and predictable high-performance backfill. It can be used to stabilise cement slurries for cemented rock fills, cemented hydraulic and cemented paste backfills.

Recommended uses:

• Stabilisation of cement slurries for cemented rock fills

• Stabilisation of cemented paste, cemented hydraulic fills, and high-density hydraulic fills.

What Makes MasterRoc MF 705 a Unique Solution?

MasterRoc MF 705 admixture retards or stabilises setting time by controlling the hydration of Portland cement and other cementitious materials to facilitate pumping and placing operations.

What Are the Benefits of MasterRoc MF 705?

• Reduced water content leading to higher in-situ compressive strengths

• Controlled setting time characteristics

• Improved slump flow characteristics

• A longer workability retention (open time)

• Provides flexibility in the scheduling of backfilling operations

• Dramatically reduces potential of pipe blockages due to control of cement hydration and setting time

  • Up to 25% increase in batches per day

  • Up to 45% decrease in flushing of pipes

  • Provides the opportunity for “Hot Change” between shifts

• ​Reduces piping replacement costs

• Reduces pressure losses and longer transportation distances

• Improved reliability of fill delivery and increased production

• Increased compressive strength

• Mix optimization and/or cost savings by binder reduction (cement/slag cement/flyash)

• Cleaner mixing and agitator tanks​
