Only about 50–60% of the total fly ash produced by the power plants is currently being reused while the residual is discarded in ash ponds. It is imperative to avert putting of fly ash generated from power stations on land and encourage fly ash utilisation for construction and other activities. ... good thermal insulation, easily processing ...

Georgia Power recently announced its third coal ash reuse project for Plant Branch in Milledgeville, Georgia. Plant Branch began commercial operation in 1965 and was retired in 2015.

The physico-chemical and structural characteristics of the fly ash coming from various worldwide power plants are briefly presented. The fly ash was sampled from power plants where the combustion of lignite and hard coal in pulverized-fuel boilers (PC) and circulating fluidized bed (CFB) boilers was applied. The fly ash has high silica content.

Fly ash was obtained as dry fly ash from hoppers or as ponded fly ash from a power plant pond or a stockpile. A systematic laboratory study on extruded fired bricks containing up to 70 wt% dry fly ash showed that the fired bricks had greater compressive strength (Fig. 7 ) [ 106 ] and lower thermal conductivity [ 107 ] than conventional bricks ...
