Bottom Ash is formed in the firing chambers of boilers at electric utility power plants in the U.S. and around the world. Bottom ash is particles of ash that have been fused together at high temperature to form slag like material for use as lightweight and conventional aggregate.


  
 
 
 

The bottom ash aggregate may be graded to meet the requirements of ASTM C 331 Specification for lightweight aggregate for use in concrete Masonry units. This ash aggregate usually has a unit weight of 60 - 65 pounds per cubic foot. This aggregate may also be blended with other lightweight aggregates to achieve greater quantities.

Ash aggregate may also be used as conventional aggregates for use in asphalt, concrete, and road construction.


  
 
 
 

Bottom ash may also be used as raw material in the manufacture of portland cement and as fill material.

Power plant bottom ash is very versatile material and may be produced from either class F or C ash.
