Description

MasterFlow 928 is a specially prepared, ready-to-use, nonshrink, high-strength grout. The product contains sulphate resistant Portland cement (HSR LA). It is formulated for use at any consistency from fluid to damp pack for precision grouting of equipment, concrete systems, structural building members, curtain walls, precast wall panels, beams and columns. It contains natural aggregates and provides a grout that is similar in appearance to mortar. The maximum grain size is 1,4 mm.

Areas of Use

MasterFlow 928 is recommended for:

• Grouting precision equipment, baseplates, soleplates, and columns with a typical layer thickness of 2,5 cm up to 5 cm.
• Grouting application where shrinkage must be eliminated and where high-strength grout similar in appearance to mortar is required or desired.
• Non-shrink grouting of precast wall panels, beams and columns, anchor bolts and reinforcing bars.
• Use for exposure classes XC4, XF4, XD3, XA3 according to EN 206-1 (Concrete standard).

In optimal conditions MasterFlow 928 can also be applied from 10 mm -100 mm. For a layer thickness above 100 mm we recommend the use of MasterFlow 980.
