An Experimental Study on the Shear Behavior of Reinforced Concrete Beams using Recycled Coarse Aggregate

재생굵은골재를 사용한 철근콘크리트 보의 전단거동에 관한 실험연구

The structural behavior of the members using recycled coarse aggregate is investigated in this papers. The members considered this study are subjected to shear ad bending simultaneously. A series of test beam specimens using recycled coarse aggregate is made for the structural test. These specimens are manufactured using the concrete for the compressive strength of 280kg/$\textrm{cm}^2$ with recycled aggregate ratio of 0%, 20%, 40%, 60%, 80% of total aggregate volume, respectively. The main object of this test is to investigate the influence of the using recycled aggregate to the cracking strength of the member subjected to flexure and shear and the post cracking behavior.
