Conbex Backfill Cementitious Binder

Conbex Backfill is a blend of cementitious powders that act as a binder for milled mine tailings used in back-filling.

Details
Fillset Additive System for Cemented Backfill

The Fillset system can be used to produce a stiff cemented backfill, the characteristics of which can be designed to suit specific backfilling requirements.

The Fillset system consists of two components,  a powder, Fillcem and a liquid, Fillgel. When added to tailings slurry, the components react in time to form a homogeneous hardened backfill. 

Fillcem is a blend of specially selected powders proportioned to give a long pipe life and optimum strength development in the backfill. 

Fillgel is an inorganic liquid additive, which when added to the slurry reacts rapidly with the components of Fillcem to accelerate solidification with minimal water loss.
