CEMENTITIOUS HIGH STRENGTH NON-SHRINK PRECISION GROUT
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.
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
Concrete repair applications where a form and pour material is required
Applications requiring high early compressive strengths and high ultimate compressive strengths
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”.
