sustainable application of cenospheres in cementitiouswhite cenospheres
Coal Combustion Scientific.Net
Cenospheres are light low density thin-walled hollow ceramic microsphere with unique properties. Conventional cenosphere production methods involve the separation of cenospheres from coal fly ash. Due to its small quantities in fly ash (1 wt.) separation process results in low production of cenospheres.
