Fly ash used to create alternative building product
Autoclaved Cellular Concrete (ACC), a new, concrete-like block containing 70 percent fly ash, is proving to be a superior alternative to concrete, wood and paper products. The ACC block, currently being promoted by the Electric Power Research Institute (EPRI), could reduce both the overall cost of generating electricity from coal and the need for landfill space. The typical fly ash concrete mixture is 4 to 5 percent fly ash. {open_quotes}It doesn`t take a brain surgeon to see that these blocks are a much better outlet for fly ash than the current concrete mixture,{close_quotes} said Dean Golden, EPRI`s project manager. Golden estimates that a typical coal-fired plant can save an average of $10 per ton in landfill costs alone by converting its principal by-product to these blocks. Besides fly ash, the blocks also contain water, cement, lime and aluminum powder.
