Because fly ash is a byproduct of coal, which itself is full of heavy metals and toxins that can be dangerous, concern has been raised that buildings made from fly ash concrete could be harmful to people. The biggest challenge to fly ash came in 2008, following the massive fly ash spill at the Kingston Fossil Plant in Tennessee (see sidebar).
Figure 1 shows fly ash produced in a typical pulverized-coal-fired utility boiler and collected by an electrostatic precipitator.

Fly ash is one of them. The use of Fly ash with soil and firing the bricks with agricultural waste will reduce the cost of the building material i.e. Clay bricks. Fly ash can be utilized in the manufacture of fired, unfired, and steam cured bricks. Fly ash bricks have several advantages over conventional burnt clay bricks.
Another type of fly ash brick is made by mixing soil, Plaster of Paris (POP), fly ash and water, and allowing the mixture to dry. This method reduces air pollution as no heat is required. Roller Compacted Concrete (RCC) Fly ash is also used in roller compacted concrete dams. It lowers the heat of hydration allowing thicker placements to occur.
