Technology Background of Ultrafine Fly Ash
The HITEPOZZO® – UFFA series is a new generation, high-reactivity ultrafine fly ash developed through advanced material research and precision process engineering. It is a performance-driven mineral admixture designed for next-generation cementitious systems & high performance concretes.
Produced from carefully selected fly ash and processed using state-of-the-art controlled multi-stage classification and advanced refinement technology, HITEPOZZO® – UFFA features a narrow particle size distribution and significantly enhanced specific surface area.
These engineered characteristics improve particle packing density and reactivity within cementitious matrices, enabling higher strength development, improved durability, enhanced workability and rheological performance.
Classified Fly Ash Vs Ultrafine Fly Ash HITEPOZZO® - UFFA
Compared to conventional classified fly ash, HITEPOZZO - UFFA Ultrafine Fly ash products demonstrates very fine particle size, narrow particle size distribution, increased specific surface area, refined pore structure, improved physicochemical characteristics, enhanced particle packing efficiency, reduced permeability and consistent strength improvement, etc.
Advantage of Ultrafine Fly Ash HITEPOZZO® - UFFA in Advanced Concretes
Reduced Water - Cement Ratio & Increased Workability
The higher percentage of spherical particles in HITEPOZZO® – UFFA acts as a solid-state plasticizer (in addition to the regular plasticizer}, improving workability and reducing water–cement ratio.
Increased Durability
Being significantly finer than cement and other supplementary cementitious materials (SCMs), HITEPOZZO® – UFFA fills micro-voids, reduces or eliminates capillary bleed channels, and enhances concrete density and resistance to chloride and sulphate attacks.
Enhanced Strength
In addition to the regular cementitious matrix formation in the concrete, HITEPOZZO® – UFFA reacts with free lime [Ca(OH)₂] released during cement hydration to form additional highly stable and stronger calcium silicate hydrate (C-S-H) gel. This results in stronger bonding, denser microstructure, and increased compressive strength...
