Our 27+ years of experience in processing and distribution of Fly Ash keeps us at the spearhead of the industry.
What is Fly Ash
Fly Ash (pulverized fuel ash) is a byproduct of a 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 the coal combustion process and the selection process. This, in turn, affects the quality of Fly Ash utilization. Therefore, it is important that when considering the use of Fly Ash, one should look for a company with the in-depth technical knowledge and support to manufacture and supply a high-quality product, which we pride ourselves in being.
Leveraging Technology to Elevate Quality
Ashtech strives to provide 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 an optimum 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 Fly Ash, namely: 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.
