Description
Darafill capsule Controlled low strength material (CLSM) performance additive produces a cementitious material that is highly flowable, volume stable and excavatable in the future. Darafill capsule is a viscous solution of organic compounds used in cementitious backfill mixtures.
By developing a stable-air matrix in the CLSM mixture, Darafill capsule improves flowability and reduces the required amount of mix water up to 50%, compared to a water-based CLSM.
Application areas
- Central mix operations
- Cement and pozzolans such as fly ash and ground blast furnace slag
- Trenches, tanks and pipes
- Trenches, undercuts and voids that requires safe leveling and high lateral flow fills
- Future excavation requirements that control strength development
Benefits
- Improves flowability, lowers densities, settlement and control strength development
- Enhances plastic and hardened properties of CLSM
- Aids pumpability and minimises segregation in pump between loads
- Reduces buoyancy problems in CLSM (embedded pipes) compared to water based CLSM
- Cost-effective compared to compacted soil by increasing efficiency of labour and equipment
- Minimises settlement in comparison to compacted-soil backfill
Packaging
- Bulk
