Recycled concrete can be used as aggregate in new concrete, particularly the coarse portion. When using the recycled concrete as aggregate, the following should be taken into consideration: Recycled concrete as aggregate will typically have higher absorption and lower specific gravity than natural aggregate and will produce concrete with slightly higher drying shrinkage and creep.

uses of recycled concrete aggregates (also conclusion uses) :- Strength of concrete block made of recycled concrete aggregate is less than that of natural aggregate. So the choice of using recycled aggregate for concrete block is less preferable but using it for filling, subgrade layers of pavement and more applications (which are given below) could be good choices.
