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
