Effect of Recycled Aggregates, Concrete

They answer this question as follows: Recycled aggregates typically have higher absorption and lower specific gravity than natural aggregate and produce concrete with higher drying shrinkage and creep. These differences become greater with increasing amounts of recycled fine aggregates. Too many recycled fines also can produce a harsh and unworkable mix.
