MasterRoc SA 184
Alkali-free, liquid high performance set accelerator for sprayed concrete
MasterRoc SA 184 is a high-performance, suspension type alkali-free set accelerator for sprayed concrete. The dosage can be varied to the desired setting and hardening requirements.
Areas of Application
- Temporary and permanent ground support in tunneling and mining
- Slope stabilization
- Also suitable for acceleration of cementitious grouts, such as for annulus grout in TBM tunnels, cemented ground injection and foam concrete.
- All applications where high early strength, high final strength, very large layer thickness in a single application are required
Characteristics and Benefits
MasterRoc SA 184 is ideally suited for wet mix sprayed concrete for ground support:
- The quick setting property allows rapid work progress and the ability to construct thick sprayed concrete linings via layered application during one construction sequence.
- The unique product formulation provides fast setting, continuous early-age strength development high durability and good long-term strength.
- Very low dust generation during application and therefore a good working environment.
- Possibility of low rebound applications when using the correct nozzle angle and distance.
- Non-aggressive properties provide improved working safety, reduced environmental impact and lower handling costs.
- Alkali-free
- Chloride free: no impact on reinforcement steel
