 Abstract
This paper deals with the result of thermal resistance test with backfill materials as bottom ash by using backfill material. Bottom ash, one of coal ashes, can be reused to replace sand because of its similar engineering properties. But without considering the thermal property, the abuse of bottom ash resulted in damage for existing structures. To investigate the thermal conductivity of bottom ash, laboratory tests for thermal resistance of that were carried out in this study. Thermal properties of bottom ash was compared with those of in-situ soil, sand, backfill material which can be applied as filling material. The tests were classified by water contents defined as the major influence factor. The beneficial use method of bottom ash was suggested as backfilling material.
