A Experimental Study on Properties Matter of Recycle Aggregate Concrete Crush Method Waste-Concrete - Focused on the Recycle Aggregate used Electrical Crusher System in Underwater -

폐콘크리트 파쇄 방법에 따른 재생골재 콘크리트의 물성에 관한 실험적 연구 - 전기충격식 수중파쇄 시스템을 이용한 재생골재를 중심으로 -

The production accounts of domestic by-product is increased after 1990's. It is worried about the life reduction of dump land, as dump land's capacity have reached to limitation and the amount of construction industrial wastes is going higher Recently, Recycling aggregates could be gained from the reconstruction works using recycle process. and the study and research of recycle concretes developed concrete application methods, It could put some outcome of studies to practical use for concrete products. The methods of crushing waste concrete are going diverse. In this study, the fundamental experiments and recycling application is investigated and analyzed with use of recycling aggregate which made of mechanical crush and underwater electrical impact crush. and the difference between underwater electrical impact crush, mechanical crush and natural aggregates is studied.
