콘크리트용 골재로서 열병합 발전소용 열원 폐재 파쇄물의 활용성에 관한 연구

This study is as a part of the new disposal and recycling plans of heat-resource waste of Daegu dyeing industrial center. We tried to examine applicable possibility of crushed thing(waste aggregate) as aggregates for mortar and concrete. To examine applicable possibility of waste aggregate as a lightweight-aggregate for concrete and mortar, we carried this study by mainly property examination of concrete according to replacement ratio of waste aggregate. We tested out slump, unit weight, compressive strength and test according to replacement ratio of waste aggregate. As the results of that, if we use waste aggregate, lightweight of concrete and mortar will be possible. Specially it shows a strength improvement effect of cement hardening according to using this so it is judged that applicable possibility as aggregate for concrete and mortar is very excellent.
