MasterFlow 1206

Universal post-tensioning duct grout for highly stressed steel

Formerly: Masterflow 1341

How does MasterFlow 1206 work?

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.

Recommended uses:

Void filling grouting in restricted spaces in vertical ducts and spaces where grout will be in contact with highly stressed steel, especially in the following applications where other duct grouts produce excessive bleeding:
Horizontal, inclined, and vertical post-tensioned tendon configurations
Off shore oil platforms
Vertical bridge components
Water tanks
Post-tensioned concrete tank containing liquids
Nuclear power plants
Other vertical duct applications

What are the unique features of MasterFlow 1206?

Bleed free for vertical heights up to 100 ft (30.5 m)
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
