Description
AC-DUR-BOND is a specialized two-component epoxy formulation engineered for bonding fresh cementitious materials to existing concrete. Ideal for both vertical and horizontal structural connections, it creates a permanent, high-strength bridge between old and new surfaces, even when temporary formwork is required.
Core Advantages
- Exceptional Bond Strength: Delivers a bond stronger than the tensile strength of high-quality concrete, ensuring structural monolithic behavior.
- Extended Open Time: Provides up to 2 hours after application to place new concrete, eliminating the risk of delamination.
- Corrosion Shield: Acts as a barrier that prevents the migration of chloride ions from old contaminated concrete to the new repair segment.
- Moisture Tolerant: Can be safely applied to wet or moist concrete surfaces without compromising adhesion.
Ideal Applications
- Structural Extensions: Lengthening of columns, beams, walls, and slabs.
- Jointing: Seamlessly connecting old and new concrete floors in industrial or commercial settings.
- Infrastructure: Bridge rehabilitation, road repairs, and water-retaining structures.
- Heavy-Duty Concreting: Connections in industrial plants and high-rise structural elements.
Pro Tip: AC-DUR-BOND is the preferred choice for critical structural repairs where the new concrete must be supported by formwork, providing the necessary window for complex pours.
