MasterFlow 880 is a non-shrink, iron reinforced precision grout with high early and ultimate strengths. It is formulated to provide extended working time even at high ambient temperatures when mixed and placed at any recommended consistency. MasterFlow 880 is normally placed at a flowable consistency to completely fill voids between 10mm and 100mm.

Especificação

RECOMMENDED USES MasterFlow 880 is used for all precision, non-shrink grouting applications with clearances of 10mm or more, particularly those requiring maximum dynamic load bearing and impact resistance such as: • critical equipment baseplates, soleplates & columns • crane rails, ball mills, crushers • rolling, stamping, drawing and finishing mills for the steel and aluminium industries • turbines, generators, pumps and centrifugal compressors • anchor bolts and bars • “H” shaped steel columns, steel tube columns • applications requiring high early compressive strengths and high ultimate compressive strengths. FEATURES AND BENEFITS • Iron reinforced – Contains inert iron aggregate as internal reinforcement – Provides improved resistance to heavy impact, vertical and horizontal repetitive loading as well as rotational torque. • High early strength – ensures rapid commissioning of new equipment and structures. • High ultimate strength – ensures permanence of the installation under static and repetitive loads. • Flowable long life grout – easy to grout intricate spaces normally inaccessible by conventional grouting techniques. • Extended working time – facilitates grouting of large or difficult placements in a single pour, often without the use of a pump. • Economical – greater volumes of grout can be mixed and handled with less labour. • 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”.
