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).

Product Highlights:

• 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
• Low-dusting for added worker comfort and safety
• NSF/ANSI 61 Std for use with potable water
• Pumpable
• Extended working time
• Can be mixed at a wide range of consistencies
• 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
