​​MasterFlow 870

CEMENTITIOUS HIGH STRENGTH NON-SHRINK PRECISION GROUT

Description

MasterFlow 870 is a non-shrink, natural aggregate precision grout with excellent high early and ultimate strengths. MasterFlow 870 is normally placed at a flowable consistency to completely fill voids between 10mm and 100mm.

Uses

MasterFlow 870 is used for all precision, non-shrink grouting applications with clearances of 10mm to 100mm, including:

Critical equipment baseplates, soleplates & columns

Precast wall panels, beams, columns, structural building members and curtain walls

Patching poured in place concrete structures, e.g. honeycombing, using preplaced aggregate techniques

Underpinning

Concrete repair applications where a form and pour material is required

Applications requiring high early compressive strengths and high ultimate compressive strengths

Advantages

High early strength – ensures rapid commissioning of new equipment and structures

High ultimate strength – ensures permanence of the installation under static and moderate repetitive loads

Flowable long life grout – easy to grout intricate spaces normally inaccessible by conventional grouting technique

Extended working time – facilitates grouting of large or difficult placements in a single pour, often without the use of a pump

Dense, non-shrink grout – hardens free of bleeding, settlement and drying shrinkage, ensuring tight contact with all grouted surfaces

Easy to use – requires no special mixing equipment, it can be mixed in a standard concrete mixer or in a pail using a grout stirrer

No added chloride – does not add to chloride load of structure

Compliance with codes – meets the non-shrink requirements of ASTM C1090 and CRD-C 621, Corps of Engineers Specification for Non Shrink Grout; provides complete non shrink performance when tested in accordance with simulated Bedplate Technique; tested to the requirements of AS1478.2 “Methods of sampling and testing admixtures for concrete, mortar and grout”.
