Fly Ash/Coal Ash

Fly ash is produced principally at coal-fueled electric power plants, which is one of the residues generated in the combustion of coal. Owing to its pozzolanic properties, fly ash is used as a replacement for some of the Portland cement content of concrete.It can improve concrete performance, making it stronger, more durable, and more resistant to chemical attack. The reuse of fly ash also creates significant benefits for our environment.

1. Introduction.

Fly Ash is one of the residues generated in the combustion of coal, and generally captured from the coal-fired power stations. Depending upon the source and makeup of the coal being burned, the components of Coal Fly Ash vary considerably, but all Coal Fly Ash includes substantial amounts of silicon dioxide (both amorphous and crystalline) and calcium oxide.
