High-precision mineral-aggregate grout with extended working time
Formerly: Masterflow 928 Grout
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).
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
ANSI/NSF 61 certified for use with potable water
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
