Coal ash is a general term...just like soda is a general term. Soda comes in many varieties and mixtures...likewise coal ash varies tremendously depending on the source and contents. Coal ash also has many other "names" such as Coal Combustion Residuals (CCRs), Coal Combustion Byproducts (CCBs), Coal Combustion Wastes (CCWs) and Fossil Fuel Combustion (FFC) wastes, but generally it is a term that collectively includes materials such as coal: fly ash, bottom ash, boiler slag, and flue gas desulfurization materials.
Coal is a rock made from formerly living green plant etc material...hence it contains carbon combined with indigenous rock/dirt/soil commonly found in the coal mining region. Carbon is a substance that "burns" and generates BTU's. Accordingly coal ash is a mixture of the indigenous rock/dirt/soil found in coal (and the local area) minus the carbon. The ash material has been safely and beneficially used since the time of the Roman Empire. Today in many states it is beneficially used in a highly regulated fashion...some of the many beneficial uses are:
1.Concrete/concrete products/grout
2. Blended cement/raw feed for clinker
3. Gypsum panels (e.g., wallboard)
4. Flowable fill
5. Structural fills/embankments
6. Road base/sub-base/paving
7. Soil modification/stabilization
8. Mineral filler in asphalt
9. Snow and ice control
10. Blasting grit-Roofing granules
11. Mine placement/reclamation
12. Waste stabilization/solidification
13. Agriculture
14. Aggregate
