Conbex™ Backfill Binder

Conbex Backfill Binder is a blend of inorganic cementitious powders that act as a binder for milled mine tailings used in backfilling.
The required percentage of Conbex must be determined by actual test, using the actual tailings and actual mine conditions. Typical additions are 5-8% to obtain 1.0 MPa after 28 days.
The rate of strength gain can be affected by the following:
- Wet density (solids content)
- pH
- Particle size distribution
- Dissolved chemicals
- Temperature

- 1 Ideal for high water content tailings slurries
- 2 Superior strength development
- 3 Lower cost than pure cement systems
