Penetration of ash particles into the respiratory tract is largely dependent on particle size. Larger particles (10-100 µm diameter) lodge in the upper airways, while those in the 4-10 µm size range deposit in the trachea and bronchial tubes. Very fine ( 4 µm diameter) particles may penetrate deeper into the lungs, into the alveolar region.

the fly ash as the sole cementing material (Cross 2005). In addition to providing an indication of the mineralogy and reactivity of the fly ash, the calcium content is also useful in predicting how effective the fly ash will be in terms of reducing the heat of hydration (Thomas 1995), controlling expansion due to alkali-silica reaction (Shehata

The continual growth of pulp and paper industry has led to the generation of tremendous volumes of fly ash as byproducts of biomass combustion processes. Commonly, a major part of it is landfilled; however, updated environmental regulations have tended to restrict the landfilling of fly ash due to rising disposal costs and the scarcity of suitable land.
