Description
Aluminium-Free Poly-Ceramic Grout Admixture
AC-CABLE-GROUT-HF is a specialized, aluminium-free poly-ceramic admixture for high-performance cementitious grouts. It provides a powerful plasticizing effect and positive expansion to counteract shrinkage, ensuring a dense, durable fill for critical structural ducts.
Key Advantages
- Aluminium-Free Safety: Advanced poly-ceramic formula contains no aluminium, chlorides, or nitrates.
- Zero Shrinkage: Positive expansion compensates for plastic settlement and volume loss.
- Optimal Flow: Reduces water-cement ratio while maintaining a smooth, pumpable, or free-flow consistency.
- High Durability: Produces an impermeable, high-strength grout compatible with all fresh cements.
Ideal Applications
- Post-Tensioned Infrastructure: Bridge girders, decks, and large-span slabs.
- Prestressed Elements: Precision duct grouting for structural integrity.
- Heavy-Duty Tanks: Tension grouting for silos and liquid-retaining structures.
Application Highlights
- Dosage: 250g per 50kg bag of fresh cement.
- Mixing: 400–500 RPM mixer; add water first, then cement and admixture.
- W/C Ratio: Strictly ≤ 0.45 for a creamy, bleed-free mix.
- Injection: Keep grout agitated until use; do not add water after initial mixing.
