​MasterFlow 980HF - High performance, high flow, hydrogen free, non-shrink cementitious precision grout for greater application thicknesses

MasterFlow 980HF is a ready to use, factory quality controlled, fine grey cementitious powder which has been formulated with larger aggregates allowing the grout to be installed in thicker sections. It requires only the on-site addition of water to produce a high performance, high flow, non-shrink precision grout with predictable, consistent properties. Special additives ensure hydrogen free expansion in the fresh plastic and the hardened stages to ensure the grout maintains full contact, and efficient load transfer, with the underside of baseplates, or within the void to be filled. 

MasterFlow 980HF is formulated for use at any consistency from fluid to damp-pack, and may be used with confidence for bedding, grouting and precision bearing operations such as:

• Gas or steam turbines

• Generators

• Presses

• Crane rails

• Milling machines

• Precast elements

• Anchor bolts

• Suitable for use in bridge bearing applications

• Form and fill concrete repairs

• It is particularly suited for situations where hydrogen expansion grouts are not allowed 

• Non-shrink in plastic and hardened form.

• Formulated for application in thicker sections > 100mm.

• Lower exotherm, therefore lower heat gain in thick sections.

• Proven and predictable performance.

• Excellent workability retention even at high ambient temperatures.
