Aggregate-free cable and duct grout

How does MasterFlow 816 work?

Masterflow 816 cable grout is a cement-based aggregate-free grout. It produces a fluid, pumpable, non-shrink, non-bleeding, high-strength product with extended working time. It provides corrosion protection for highly stressed steel cables, anchorages, and rods.

Product Application

Recommended uses:

Pumping around pre-tensioned or post-tensioned cables and rods
Placing around end sections of unanchored cables and rods
Non-shrink grouting in restricted spaces between precast wall panels, beams, and columns
Grouting cable anchor plates where grout contacts highly stressed anchorages
Conventional grouting applications with clearances over 1/4" (6 mm) but under 1" (25 mm)
Vacuum grouting for repair of voids in previously grouted post-tensioned tendons
Inclined and horizontal post-tensioned tendons

What are the unique features of MasterFlow 816?

Non-shrink / hardens without bleeding or resultant voids
Protects tendons from corrosion
Can achieve 20–30 second flow per ASTM C 939
Flow Cone Method
Suitable for conventional grouting where clearances are between 1/4 to 1" (6–25mm)

What are the benefits of MasterFlow 816?

Free of fine aggregate for maximum penetration into small spaces, between wire strands
Long working time and recirculation possible at temperatures up to 90° F (32° C)
