FLYASH
Fly Ash is a by product of coal based thermal power station generated by the combustion of pulverised coal. Fly ash is a fine, grey amorphous powder. It is rich in silica & alumina and spherical in shape.
CHARACTERISTICS OF FLYASH
Fine Particle Size
Low Carbon Content
Spherical Particle Size
Pozzolanic Reaction
CONCRETE APPLICATION
Better Workability
Reduced Permeability
Improved Pumpability
Better Concrete Finish
Reduced heat of Hydration
Increased Long term Strength
