Comprehensive Characterization of Grounded Bottom Ash from Indian Thermal Power Plant

In present work, an attempt has been made to improve the quality of bottom ash for utilization as a pozzolanic material. All samples were crushed and passed through 250 µm sieve to prepare grounded bottom ash. The physio-chemical, mineral and leaching characteristics of original and grounded bottom ash were studied. Results show that specific gravity and bulk density of all sample increases whereas porosity, water holding capacity and loss of ignition decreases after the grounding the bottom ash. Pozzolanic properties of bottom ash also improved after grounding the ash samples which helps to commercialize its utilization and reduce environmental impact.
