Fly Ash . Fly ash is a fine, powdery substance that "flies up" from the coal combustion chamber (boiler)and is captured by emissions controls, such as an electrostatic precipitatororfabric filter "baghouse," and scrubbers.. This material is virtually identical in its composition to volcanic ash with pozzolanic properties ideal for concrete that built the structures of Ancient Rome we ...
Nebraska Ash was formed in 1976 for the purpose of handling coal combustion byproducts known as fly ash and bottom ash at coalfired electric generating stations (power plants). Nebraska Ash provides services such as marketing, storage and disposal for these power plants located in Colorado, Kansas, Iowa and Nebraska.
Fly ash is a byproduct of coal combustion in power stations. Aside from offering environmental advantages by reusing industry waste, adding fly ash also improves the overall performance and quality of concrete. Fly ash affects the plastic properties of concrete by improving workability, reducing water demand, controlling bleeding, and lowering the heat of hydration.
