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
