Pros
Reduces green house gas emission as a cement replacement material
For every one ton of cement produced about 6.5 million BTUs of energy is consumed. Replacing that 1 ton of cement with fly ash would save enough electricity to power the average American home for almost a month.
For every one ton of cement produced about one ton of carbon dioxide is released.
Reduces volume of landfill space used for disposal of fly ash
