Abstract We elucidated the effects of the parent concrete and mixing approach used on the freezing/thawing resistance of air-entrained recycled aggregate concrete (ARAC). Three non-air-entrained concretes and one air-entrained concrete were used to prepare recycled coarse aggregate (RCA) samples. Three mixing approaches were also investigated.
