DESCRIPTION MasterFlow 870 is a non-shrink, natural aggregate precision grout with excellent high early and ultimate strengths. It is specially formulated to provide extended working time even at high ambient temperatures when mixed and placed at any recommended consistency. Masterflow 870 is normally placed at a flowable consistence to completely fill vooids between 10mm and 100mm. Thicnesses greater than 100mm are possible with the addiction of aggregate.
RECOMMENDED USES MasterFlow 870 is uses for all precision, non-shrink grouting applications with clearances of 10mm or more, including : * Critical equipment baseplates, soleplates & columns. * Precast wall panels, beams, columns, structural building members and curtain walls. * Patching poured in places concrete structures. * E.g honeycombing, using preplaced agregate techniques. * Underpinning. * Concrete repair applications where a form and pur material is required. * Application requiring high early commpressive strengths and high ultimate compressive strenghs.
FEATURES AND BENEFITS * High early strength - Ensures rapid commisioning 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 normallly inaccessible by convensional 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 suraces. * 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.
