The present study describes the comparative assessment of Particle size distribution profiles of Coal Combustion Residues from two thermal power stations of Korba, Chattisgarh, India. Knowledge about Particle size is indispensable to determine the possibility of usage of these Coal Combustion Residues in various applications. Coal combustion Residues of CSEB-E power plants were found to have better particle size distribution profile than CSEB-W power plant. CSEB-E power plant had AMD from 15.83 to 66.91 and CSEB-W 49.48 to 75.36. The particle size analysis reveals that the samples which have the highest undersize percent by volume in the particle size range of <45 are useful as fillers in construction materials. They may also be used in geotechnical applications, bulk utilization through back filling, reclamation of waste degraded land and for stowing in underground mines.
