MasterRoc SA 194
Alkali-free, liquid high performance set accelerator for sprayed concrete 
How does MasterRoc SA 194 work?
MasterRoc SA 194 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.
What is MasterRoc SA 194 used for?
- Temporary and permanent ground support in tunneling and mining 
- Slope stabilization 
- Acceleration of cementitious grouts, such as for annulus grout in TBM tunnels, cemented ground injection and foam concrete 
- Applications where higher early strength and larger layer thickness in a single application is required 
What are the benefits of MasterRoc SA 194?
- Quick setting property allows rapid work progress and the ability to construct thick sprayed concrete linings via layered application during one construction sequence 
- Unique product formulation provides fast setting, continuous early-age strength development, high durability and good long-term strength 
- Very low dust generation during application, providing 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
