MasterRoc MF 507 - High-performance plasticizing and water-reducing admixture for mine backfill mixes


Formerly: MEYCO Minefill 507

How does MasterRoc MF 507 work?

MasterRoc MF 507 is a ready-to-use high-range water-reducing admixture. MasterRoc MF 507 admixture is particularly effective in improving the consistency of the backfill mixtures. This is accomplished by providing unparalleled slump retention without compromising early-age compressive strength development and setting time. Workability retention helps to maintain more consistent performance from batch to batch, thereby improving operational efficiencies. Backfill produced with MasterRoc MF 507 admixture maintains slump significantly longer than backfill made with other high-range water-reducing admixtures. This slump retention is achieved without affecting rate of hardening or early-age compressive strength development.

Recommended for use in:

  • Backfill requiring high early compressive strength development
  • Backfill where high flowability, increased stability and durability are needed
  • Backfill with varying water reduction requirements (5-40%)
