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
