Universal post-tensioning duct grout for highly stressed steel
MasterFlow 1206 is a cement based product with specially graded spherical aggregate that produces a
pumpable non-bleeding high-strength grout. It has extended working time, especially in vertical duct
placements or configurations with a steep vertical rise without settlement shrinkage. It is bleed resistant for
horizontal, inclined, and vertical tendon configurations. It meets all compressive strength and vertical height
change requirements of ASTM C 1107 (CRD C 621) at a modified flow and complies with the PTI Specification
for Grouting of Post Tensioned Structures with vertical rises of 6–100 ft (1.8–30 m) or slightly more.
