MasterFlow 928

High-precision mineral-aggregate grout with extended working time

How does MasterFlow 928 work?

MasterFlow 928 grout is a hydraulic cement-based mineral aggregate non-shrink grout with extended working time. It is ideally suited for grouting machines or plates requiring precision load-bearing support. It can be placed from fluid to damp pack over a temperature range of 45 to 90° F (7 to 32° C).

Recommended uses:

• Grouting of equipment, such as compressors and generators, pump bases and drive motors, tank bases, conveyors, etc.
• Grouting anchor bolts, rebar and dowel rods
• Grouting of precast wall panels, beams, columns, curtain walls, concrete systems and other structural and non-structural building components
• Repairing concrete, including grouting voids and rock pockets

What are the unique features of MasterFlow 928?

• Meets the requirements of ASTM C1107 and US Army Corps of Engineers CRD C621 (Grades B and C), at a fluid consistency over a 30-minute working time
• NSF/ANSI Standard 61 certified for use with potable water
• Pumpable
• Can be mixed at a wide range of consistencies
• Sulfate-resistant for marine, wastewater and other sulfate-containing environments

What are the benefits of MasterFlow 928?

• Extended working time
• Freeze/thaw resistant making it suitable for exterior applications
• Hardens free of bleeding, segregation, or settlement shrinkage to provide maximum effective bearing area for optimum load transfer
• Contains high-quality, well-graded quartz aggregate for optimum strength and workability​​
