MasterRoc SA 194

Alkali-free, Liquid High Performance Set Accelerator for Sprayed Concrete

Material Description
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.


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

  • Applications where higher early strength and larger layer thickness in a single application is required


Characteristics and Benefits

MasterRoc SA 194 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
