coarse aggregate recycling process

Recycled Aggregate - an overview | ScienceDirect .

mixed aggregates (MA), composed of a mix of coarse particles of concrete and brick; fine aggregate (FA), made up of fine particles only (maximum size less than 4 mm). Such a distinction is necessary because the composition of recycled aggregate and its grading have a great effect on recycled concrete properties.

In fact, in concrete with content of recycled coarse aggregate and natural fine aggregate, a decline of elasticity modulus in relation to concrete made entirely with natural aggregate goes up to 20%, while in the case of concrete produced entirely of recycled aggregates, decline of elasticity modulus ranges from 15% to 45% in relation to natural aggregate concrete.

Use Of Recycled Aggregate In Concrete – IJERT

Shrinkage of concrete depends on the amount of recycled concrete aggregate. Concrete with more than 50% of recycled coarse aggregate has significantly more shrinkage compared to concrete with natural aggregate. Increased shrinkage is a result of the attached mortar and cement paste in the recycled aggregate grains.
