Where Is Post Tensioning Grout Used?
Post tensioning grout is used wherever high-tensile steel tendons need to be fully encased and protected inside a duct after the surrounding concrete has cured. ARDEX CE 901 is suited to:
– Grouting of post-tensioning cable ducts, both horizontally and vertically
– Grouting of small openings over long pumping distances
– Soil and rock grouting
– High-flow grouting applications where the grout must reach every part of the duct without voids
Because it is aggregate-free and ultra-fluid, ARDEX CE 901 pumps cleanly through narrow or congested ducts, reducing the risk of air pockets that could otherwise leave sections of the tendon unprotected.
What is post tensioning grout used for?
Post tensioning grout fills the duct around post-tensioned steel tendons after stressing, protecting the tendon from corrosion and bonding it permanently to the surrounding concrete. It’s a critical step in bonded post-tensioning systems used in bridges, slabs, and other structural elements.
Is ARDEX CE 901 a non shrink grout?
Yes. ARDEX CE 901 is formulated to resist shrinkage during curing, so it maintains full contact with the duct wall and tendon as it sets. This dimensional stability is essential for reliable corrosion protection in post tension grouting work, the same non shrink grout principle used across ARDEX-QUICSEAL’s structural grouting range.
