Description
Expanding Admixture for High-Performance Duct Grouting
AC-CABLE GROUT is a specialized powder admixture designed for cementitious grouts in post-tensioned and prestressed structures. It enables a low water-cement ratio while providing controlled gaseous expansion to permanently eliminate shrinkage and settlement.
Key Advantages
- Shrinkage Compensation: Positive expansion offsets plastic settlement for a solid, void-free fill.
- Superior Flow: Delivers a high-plasticizing effect for smooth, pumpable, or free-flow applications.
- Structural Integrity: Chloride-free and impermeable; ensures long-term durability and corrosion protection.
- High Compatibility: Specifically formulated for use with fresh Ordinary Portland Cement (OPC).
Ideal Applications
- Post-Tensioning: Ideal for bridge girders, decks, and large-span slabs.
- Containment Structures: Perfect for Silos and water tank tension grouting.
- Prestressed Elements: Reliable duct grouting for all heavy-duty structural members.
Application Guidelines
- Dosage: 250g per 50kg bag of fresh OPC.
- Mixing: Use a high-speed mixer (400–500 RPM) for a creamy, bleed-free consistency.
- W/C Ratio: Maintain a water-cement ratio of 0.45 or less.
- Pro-Tip: Keep the grout agitated until injection; never add extra water after initial mixing
