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)
- Particle size distribution
- Dissolved chemicals
When added to tailings slurry, the components react in stages to form a stiff cemented backfill, the characteristics of which can be designed to suit specific backfilling requirements.
Produced in our South African manufacturing site, the products undergo stringent quality testing to ensure the right product reaches your hands.
These grouts are usually supplied as 90 mm diameter x 400 mm long capsules, packed in a semi-permeable sheath.
Setting times are generally medium and fast set.
The Capram system was designed to afford an easy method of reliably achieving full column cement grouting in a hole of any size.
It can be used for pre- or post grouting, giving you the right flexibility when it matters the most.
Capram products can be used as a pumpable grout material as well as capsules, allowing for wider product application and adaptability.
The products are manufactured in South Africa and are available in the African region.
