TamCrete CG – Rock anchor bolt cement grout admixture

TamCrete CG is a unique water reducing admixture (in powder form), specially developed to enhance the flowability, stability, and thixotropic properties of cement grouts. It exhibits excellent pumping characteristics and high early strengths with water cement ratios as low as 0.23.

TamCrete CG undergoes Dual Expansion in the hydration process which eliminates shrinkage, ensuring rock bolts and cable anchors are securely and fully encased.
