FLY ASH
Fly ash is a fine powder recovered from coal-fires electric generation power plants.
Fly ash could be an expensive replacement for Portland cement in concrete and using it, improves strength, segregation and ease of pumping concrete.

WHY USE FLY ASH
- Produces various set times.
- Cold weather resistance.
- Depending on its use fly ash could produce higher strength gains.
- Can be used as an admixture.
- It can substitute Portland cement.
- It is considered as a non-shrink material.
- Produces denser concrete and a smoother surface with sharper detail.
- Great workability.
- Reduces crack problems.
- Reduce permeability.
- Reduce bleeding.
- Reduced heat of hydration.
- Produces lower water/cement ratio for similar slumps when compared to no fly ash mixes.
- Reduces CO2 emissions.
