순환골재를 사용한 원심력콘크리트의 강도 특성 연구

Abstract

Due to the demolition of old structures, primarily buildings, an amount of discharged construction wastes are increased. From the construction wastes, recycled aggregate can be used as a useful resource for concrete. However, its application to structural member is very limited. In this experimental study, the compressive strength of spun-concrete using recycled aggregate was investigated. Coarse aggregate was replaced with 100% of the recycled coarse aggregate, and recycled fine aggregate was replaced with various amount. According to the test results, the specimen of spun-concrete showed uniform compressive strength regardless the amount of replaced recycled fine aggregate.
