초록
The objective of the this study is to find the breakage index and changes in permeability of Bottom ash from thermoelectric power plants in Korea. Bottom ash was crushed by compaction according to compaction energy from 0 to 1661.4 kN/m2. The particle size distribution was estimated by sieveanalysis. The various breakage indexes were used for analyzing the change in particle size distribution and effect of compaction energy. In the result,breakage indexes were increased as compaction energy and initial upper 4.75 mm diameter ratio, but values and tendencies of breakage indexes appearedin different as calculation method of breakage indexes. The coefficient of permeability was decreased with particle breakage, but decreasing ratio ofpermeability was very small. Bottom ash has a higher permeability than the weathered soil and it is considered high usability as a permeable materials.
