Concrete physical properties with substitution ratio of recycled Coarse aggregate and recycled fine aggregate

순환굵은골재와 순환잔골재 치환율에 따른 콘크리트의 물리적 특성에 관한 연구

The main objective of this study was to evaluated the physical properties of concrete with substitution ratio of recycled fine aggregate and recycled coarse aggregate made of waste concrete. The replacement ratios of recycled coarse and fine aggregate decided 0%, 30%, 40% and 50% respectively to get the deregulate of floor space Index. The test result showed that compression strength of cylinder mold decrease with the substitution ratio increase but its strength of replaced recycled fine aggregate higher than OPC.
