In order to measure the rheological behavior of precast concrete with high volume of recycled fine aggregate, the replacement of natural fine aggregate by recycled one was carried out in dry-mix process. As results of that, it was found that as the replacement increases, strength and performance of concrete become decreased but may be recoverable by proper selection and dosage of constituents.
