Masterflow 1205 is a cement-based pumpable grout with specially graded aggregate. It produces a pumpable, nonbleeding, high-strength fluid grout with an extended working time.
- High strength grout - Provides anchorage for subsequent tensioning
- Hardens without bleeding, settlement, segregation, shrinkage or formation of voids - Ensures optimal performance in hardened state, thus providing maximum bond and long-term, protection against corrosion.
- Prepackaged and pretested - Easy to mix. Assures uniform performance with consistent quality.
- Compatible with high-strength steel - Protects stressed tendons, bolts, and bars from corrosion induced by chlorides and carbonation.
- No added chlorides - Inhibits corrosion.
- Easy to pump or pour - Ease of placement.
- Can be pumped or re-circulated for relatively long periods of time - Adds flexibility to construction scheduling.
- Can be used over a wide range of mixed grout temperatures from 45 to 90° F (7 to 32° C) - Lessens weather dependency
- Does not use aluminum powder as an expansion agent - Eliminates hydrogen embrittlement or bubble channel formation.
- Complies with the PTI Specification for Grouting of Post-Tensioned Structures - High performance grout verified by both independent and lot performance testing.
