This study investigates engineering characteristic of recycled aggregate concrete which incorporated various amount of recycled aggregate(0%, 30%, 50%, 100%). For the purpose of the investigation of engineering characteristic, compressive stress and air content, slump were evaluated. Evaluated results of compressive stress was shown that compressive stress and slump decreased depending on amount of recycled aggregate increased. On th other hand, air contents increased depending on amounts of recycled aggregate decreased.
