Metakaolin
| Metakaolin is very much different from other supplementary cementitious materials like fly ash, slag or silica fume as it is a not a by-product of an industrial process. This high reactivity metakaolin is procured from reliable manufacturers who manufacture these for specific purpose under controlled conditions as per industrial standards. |

High Reactivity Metakaolin What is METAKAOLIN?
Pozzofilz Metakaolin is processed from Kaolin clay which is transition mineralogical Dhaseto an Amorphous Alumino-silicate highly reactive substance for calcium hydroxide, a normal cement hydration by product to convert stable cement complex with very high strength and durability.
Where Metakaolin can be used ?
- High strength concrete
- Self compacting Concretes
- Shot crating, Tunneling work
- Bridges and Dams
- Nuclear power stations
- Agricultural applications (esp. silage storage, milking parlors, poultry houses)
- Marine structures; Underground structures
- Floors where high abrasion resistance is required
- Metakaolin concrete is particularly suitable for repair work also
POZZOFILZ METAKAOLIN is now PROVEN alternate to concrete users where no need to depend only on MICROS1LICA
- Excellent Workability with greater advantages of Pumpability and flow of concrete is concern.
- Increased Strength at the same level @ Microsilica is used
- Reduced Permeability
- Control of Alkali-Silica Reactivity
- Enhancement of Lower/Slower Reactivity Materials - Fly Ash, GGBS
- Reduction upto 30% of Super-Plasticizer and cost benefits
- Metakaolin can also added along with Fly ash for enhancement of strength and economy.
- Increased Service Life
- Improved Performance
- Improved Appearance in GFRC or colored Concrete
OTHER ADVANTAGES OF METAKAOLIN AGAINST MICRO SILICA
- Disperses more rapidly
- Produces a creamier consistency Requires less water and less water reducer (super plasticizer)
- Less prone to plastic shrinkage cracking
- Consolidates more easily into formwork
- Generates less bleed water
