    MasterFlow 1205 - High-performance duct grout for highly stressed steel

    What is MasterFlow 1205?

    MasterFlow 1205 is a cement-based pumpable grout with specially graded aggregate. It produces a pumpable, nonbleeding, highstrength fluid product with an extended working time. The specially graded spherical aggregate mitigates chloride migration while still allowing the product to be easily pumped over long distances through small openings. MasterFlow 1205 meets all the compressive strength and volume change requirements as per ASTM C 1107 (CRD C621) at a fluid consistency.  

    What is MasterFlow 1205 used for?

    • Pumping around post-tensioned tendons, cables, and high-strength rods to encapsulate and protect highly stressed steel from corrosion
    • Placing around end sections of unanchored cables and rods for subsequent tensioning
    • Filling voids in restricted spaces between wall panels, beams, and columns where grout will contact highly stressed steel
    • Grouting cable anchor-plates or other plates where grout will contact highly stressed anchorages  

    What are the benefits of MasterFlow 1205?

    • High compressive strengths
    • Hardens without bleeding, settlement, segregation, shrinkage or formation of voids
    • Prepackaged quality for bag-to-bag uniformity
    • Compatible with high-strength steel
    • The stable rheology, shrinkage compensation and low water content ensure excellent corrosion protection of steel tendons
    • Easy to pump or pour for ease of placement
    • Can be pumped or re-circulated for relatively long periods of time
