Admixtures to Optimize Paste Backfill Operations
Sika offers a range of mine paste backfill admixtures that can be dosed directly into the wetted out mix of the paste plant. The admixtures act as a high range water reducer and therefore provide the opportunity to significantly reduce the cement consumption of the paste operation. Sika is in position to provide extensive on site support and to support you with the right paste backfill design.
Sika applies similar principles that we use in concrete also for mine paste backfill plants worldwide using our chemical toolbox that has been refined over the past decades. We can help you to achieve the following with your backfill paste:
- Reduce binder consumption
- Improve compressive strength
- Reduce bleeding
- Facilitate paste pumping
- Reduce wear and tear of machinery and paste lines
- Speed up mine and fill cycle time
Every mine paste is different in terms of its granulometry, the chemical composition and the binder types used. Sika is experienced in analysing the different pastes in order to find the admixtures that will suit your paste best. By doing so, we are in position to deliver the competitive edge when it comes to cost reduction and mix optimization.
With our presence in more than 90 countries we are in position to give you dedicated and efficient on site support to optimize your paste fill operation. Specialized teams in all world regions will give you the support you need to improve the cost performance of the paste backfill mix.
