Specification of Master Flow 870 Grout Non-shrink
Cement
MasterFlow 870 is a precision grout of natural aggregates that does not shrink with very high initial strength and caterpillar. MasterFlow 870 is usually placed in flowable consistency to fully fill the gap between 10mm and 100mm.
MasterFlow 870 is used for all precision and non-shrinking grouting applications with 10mm to 100mm clearances, including:
Baseplates, soleplates & important equipment columns
Prefabricated wall panels, beams, columns, structural building members and curtain walls
Patches are poured in place of concrete structures, such as beehives, using preplaced aggregate techniques
Underlying
Application of concrete repairs where form and pour material is needed
Application that requires high initial compressive strength and ultimate high compressive strength
Unique features of MasterFlow 870
Specially formulated to provide long working times even at high ambient temperatures when mixed and placed in the recommended consistency.
Benefits of MasterFlow 870
High initial strength - ensuring the commissioning of new equipment and structures quickly
Highest ultimate strength - ensures permanent installation under static and moderate repetitive loads
Long-life grout that can be flowed - easily processed grout chambers are usually not accessible by conventional grouting techniques
Extension of work time - facilitates installation of large or difficult placements in one pour, often without using a pump
Solid, non-shrinking Nat - hardens free of bleeding, attachment, and drying losses, ensuring close contact with all grout surfaces
Easy to use - does not require special mixing equipment, can be mixed in a standard concrete mixer or in a bucket using a grout mixer
Does not add chloride - does not add to the chloride structure load
Code compliance - meets the requirements of non-shrink ASTM C1090 and CRD-C 621, Engineer Corps Specifications for Non Shrink Grout; provide complete non-shrink performance when tested according to the simulated Bedplate Technique; tested with the requirements of AS1478.2 "Method of sampling and testing of concrete mixing, mortar and grout".
