Environmental impact assessment of ash disposal

21-09-2016 Fly ash sample was collected from the ash disposal system of Guru Gobind Singh Super Thermal Power Plant, Ropar, and Punjab, India. The particle size distribution of fly ash was determined with the help of Malvern 3601 particle size analyzer. The pycnometer was used to find out specific gravity and bulk density as per IS: 2386(Part-3).
