Fly ashDesigning Buildings Wiki
Fly ashDesigning Buildings WikiShare your construction industry knowledge. Fly ash (or flue ash or pulverised flue ash PFA) is a by-product of the coal combustion process particularly in electricity generating power stations. It is formed when fine particulates of burned coal fuse in suspension and are driven out with flue gases. As they are driven out of the combustion chamber the

Influence of fly ash fineness and shape on the porosity
The effects of the fineness and shape of fly ash on the porosity and air permeability of cement pastes were investigated. Pulverized coal combustion (PCC) fly ash and fluidized bed coal combustion (FBC) fly ash classified into three different finenesses were used. River sand with particle size distribution similar to that of fly ash was also used for comparison.
