MASTERFLOW® 1205  

Masterflow 1205 is a cement-based pumpable grout with specially graded aggregate. It produces a pumpable, nonbleeding, high-strength fluid product with an extended working time. The specially graded aggregate mitigates chloride migration while still allowing the product to be easily pumped over long distances through small openings. It meets all the compressive strength and nonshrink requirements of CRD C 621 and ASTM C 1107, Grades B and C, at a fluid consistency.

Features

• High strength grout
• Contains no components detrimental
• Easy to pump or pour
• Hardens without bleeding, settlement
• Can be pumped or recirculated for relatively long periods of time
• Can be used at temperatures ranging from 40 to 90° F (4 to 32° C)
• Hardens without settlement shrinkage within the grout duct against water, chlorides, and rust
• Does not form hydrogen gases as an expansion mechanism channel formation

Benefits

• Provides anchorage for subsequent tensioning
• Protects stressed tendons, bolts, and bars to high-strength steel from corrosion
• Ease of placement
• Ensures optional performance in hardened state shrinkage, and formation of voids
• Adds flexibility to construction scheduling
• Lessens weather dependency
• Ensures maximum bond and long-term protection
• Eliminates hydrogen embrittlement or bubble- early
