중심축력을 받는 순환굵은골재 콘크리트 기둥의 압축거동 특성

다국어 초록 (Multilingual Abstract)

Recycling of waste concrete is beneficial and necessary from the viewpoint of environmental preservation and effective utilization of resources. For the effective utilization of waste concrete, it is necessary to use waste concrete as recycled aggregates for new concrete. However some investigations have been carried out to study the compressive behavior of reinforced concrete(RC) column with recycled aggregates such as high absorption of recycled aggregates, small-scale specimens. In this paper, four RC columns which were 400㎜×400㎜ in cross section were tested to evaluate the effect of failure behavior, compressive strength and ultimate strain on the replacement levels(0%, 30%, 60% and 100%) of recycled coarse aggregate under uniaxial compressive load. Based on the experimental results of ultimate compressive strengths, the KCI code were conservative and subsequently can be used for the compressive design of RC column with recycled aggregates.
