Cenospheres are spherical particles with a hollow center. Their concentration in fly ash varies over a wide range, from 0.01 to 4.80 wt%; but in most cases limits between 0.3 and 1.5 wt% [12], [13], [14]. The formation of cenospheres during combustion depends on the total mineral content of the feed coal and the combustion process [15], [16].

Cenosphere is considered to be the most important fraction of fly ash as it is being used in different industries due to its condescending properties such as high workability, thermal resistance ...

Industrial wastes such as fly ash, ceramic waste, silica fume, quarry dust, and ground granulated blast furnace slag (GGBS) are substituted for cement or sand to improve the qualities of the concrete.
