Metakaolin
I-Minerals metakaolin, I-POZZ™, is derived from kaolin through calcination, and is used in the cement and concrete industry as a natural pozzolan. Metakaolin undergoes rigorous testing to qualify for use in infrastructure projects demanding durability and strength.
Main characteristics of I-POZZ™ metakaolin
- Improved Compressive and Flexural Strength of concrete leading to high mechanical properties.
- Durability by reducing permeability and enhancing resistance to chloride ions and sulfates.
- Reduce Carbon Footprint by replacement of 8% to 12% in Portland cement mix designs.
- Improved Workability
- Reduce Heat of Hydration to minimize cracks in mass concrete placements.
