Post-tensioning grout is a high-performance, non-shrink cementitious material used to fill ducts around post-tensioned tendons in concrete structures. It ensures strong bonding between steel and concrete, provides long-term corrosion protection, and eliminates voids within the ducts. The grout is designed for high flowability, durability, and minimal bleeding. It’s essential for the structural integrity and longevity of bridges, buildings, and other post-tensioned systems.
