MasterRoc SA 167 - Alkali-free, liquid, high-performance set accelerator for sprayed concrete

How does MasterRoc SA 167 work?

MasterRoc SA 167 high performance alkali-free set accelerating admixture is used for sprayed concrete. It is a liquid whose dosage can be varied to achieve desired setting and hardening times. MasterRoc SA 167 admixture meets the requirements of ASTM C 1141/C 1141M, Types I/II, Grade 9, Class A.

Recommended for use in:

  • Applications where high early and ultimate strength development and thick layers are required
  • Temporary and permanent ground support in tunnels
  • Ground support in mining
  • General support in poor ground conditions
  • Slope stabilization
  • Acceleration of cementitious grouts, such as those used in annulus grouts, permeation grouts and cellular concrete

What are the unique features of MasterRoc SA 167?

  • Rapid early strength development for ground support allowing for increased advance
  • Supplied as a liquid, providing easy handling as well as improved dosing accuracy
  • Works well with mono pumps (screw pumps) and squeeze pumps
  • Chloride content <0.1%
  • Viscosity - 750 ± 250 cP (mPa.s)

What are the benefits of MasterRoc SA 167?

  • Provides extremely fast setting coupled with continual high early-age strength development
  • Excellent long-term strength and durability
  • Lower in-place costs compared to traditional accelerators
