The emerald ash borer (EAB), first detected in 2002 in North America, is rapidly spreading throughout the United States and Canada, targeting all native ash species. The loss of ash will have important economic, social, and ecological impacts, especially in areas where ash is the dominant canopy species, such as wetlands and riparian areas.
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
Furthermore, a "Fly Ash Research Workshop" was held October 13, 2014 in Munich, the day before the EUROCOALASH. The Research Workshop on "Durability of Fly Ash Concrete" was organised to allow especially face to face discussion of young researchers about …

Figure 3.11 High carbon fly ash isotherm results with six AEAs. Capacity ... 12 . Abstract . Fly ash has been shown to be an effective replacement for portland cement in concrete mixtures. However, many fly ash materials contain unburned carbon from the combustion process. Unburned carbon in fly ash …
A Class F fly ash with high carbon content may increase the required admixture dosage by as much as 5 times compared to a portland cement concrete without fly ash. A Class C fly ash with low carbon content typically requires 20% to 30% more admixture." Good quality fly ash generally reduces water demand, similar to liquid chemical water reducers.

Fly ash is a by-product from the combustion of pulverized coal, and is widely used as an ingredient in hydraulic-cement concrete. Because it improves many desirable properties of concrete, it is introduced either as a separately batched material or as a component of blended cement. Fly ash reacts with the hydrating hydraulic cement to form a cementing medium.
