Bottom ash and fly ash are by-product from thermoelectric power plants. Fly ash is recycled to various field. However, though an output of bottom ashhave increased each year, most of them is reclaimed in ash landfill. It is necessary to find a solution that bottom ash is recycled economically and knowcharacteristics of bottom ash to recycle. It is goal to investigate engineering properties of bottom ash, especially the particle breakage, to recycle that. Bottom ash was crushed by impact method according to compaction energy and then compared with or original sample and crushed it in terms of particlesize distribution and characteristics of strength. In result, after crushed it, particle finer was increased, especially 2∼0.85 mm size, than original. It wasdisplayed a tendency that internal friction of crushed sample was decreased but cohesion of it was not. Therefore, it is important to investigate theengineering properties of bottom ash in terms of the particle breakage to use construction materials for various field.
