Metakaolin

Metakaolin is a high-reactivity pozzolan, produced by calcining purified kaolinite clay at controlled temperatures. This results in a fine, white powder that significantly enhances concrete properties.

Features:

- Stimulates and increases cement hydration process
- Optimizing cement hydration
- Densifying the structure of the hydrated cement paste
- Unique and uniform particle size distribution for better viscosity
- Reacts early and rapidly
- Binds alkali ions
- Unique calcination (<800oC) to ensure optimized pozzolanic reactivity
- Reduces rapid chloride ion permeability
- Reduce autogenous and drying shrinkage
- Improved handling and colour matching

Benefits:

- Enhance production efficiency
- High early age strength: 1st day >45%; 3rd day >70%; 7th day >95%
- Reduced initial and final set times. Enhanced concrete durability
- Cohesive concrete
- Increases resistance to sulphate attack and chloride ion ingress
- Better aesthetic of concrete: minimized cracks or no cracks, stain free finished product, lightened colour of grey concrete
- Reduced water ingress
- Reducing concrete’s susceptibility to alkali-silica reaction
