Fly Ash - Fine Particle Size <45µm, Spherical Particle Shape For Enhanced Workability, Low Carbon Content With <2% Loi, High Pozzolanic Reaction For Durable Concrete

Fine Particle Size a a large proportion of our Fly Ash is predominantly less than 45Aum. The fine Fly Ash particles displace water between the cement particles and act as hydration sites for the cement, thereby improving the concretes pore structure and stimulating early strength development.

Spherical Particle Shape a The spherical particles of Ashtecha s Fly Ash improves workability when blended with cement particles. This property improves compaction and greater densities are achieved. In addition the concrete is more cohesive and is less prone to segregation.

Low Carbon Content, expressed as LOI. In spite of major international codes allowing LOI (Loss on Ignition) contents upto 5%, Ashtecha s Fly Ash is processed with a minimum a A-n-housea limit of 2%. This tightening of the specification helps in delivering a more superior, more durable concrete.

Pozzolanic Reaction a Due to the products high pozzolanicity, Ashtecha s Fly Ash actively reacts with the free lime (non-durable calcium hydroxide) and converts it into calcium silicate hydrates (CSH) which is the strongest, most durable paste fraction in concrete.
