What is Fly Ash

Fly is a by product of coal based thermal power station generated by the combustion of pulverized coal. Fly Ash is a fine, grey amorphous powder, rich in silica & alumina and spherical in shape. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process and the selection process. Therefore, it is important that when considering the use of Fly Ash to look no further than a company with the in depth technical knowledge and support to manufacture and supply a high quality product, that company is Ashtech (India) Pvt. Ltd.

"Our Technology means even Better Quality"

ASHTECH only selects Fly Ash that is highly reactive and has water reducing characteristics. Our Fly Ash is amongst the first classified and processed material being made available in India. By classifying and processing, we ensure that a large proportion of our Fly Ash is composed of fine particles, which results in a more controlled and consistent product. Our Fly Ash complies with the stringent International codes of practice such as :
BS EN 450 S, ASTM C 618 Class F and IS 3812 Grade 1
Our customers can therefore be assured of the highest standards of quality, process control and product consistency.
