Abstract Since recycled aggregate concrete (RAC) is valuable for green concrete and global sustainability, it has attracted many numerical research studies as a five‐phase material in mesolevel. In this study, the digital image processing (DIP) technique is used to obtain the real aggregate and mortar distribution of recycled concrete specimens.
