MasterRoc SA 184

Alkali-free, liquid high performance set accelerator for sprayed concrete

How does MasterRoc SA 184 work?

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.

What is MasterRoc SA 184 used for?

• Temporary and permanent ground support in tunneling and mining

• Slope stabilization

• 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

What are the benefits of MasterRoc SA 184?

• 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
