Mechanical Properties Of Recycled Aggregates Concrete

Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests. Recycled concrete aggregates contain not only the original aggregates, but also hydrated cement paste. This paste reduces the specific gravity and increases the porosity compared to similar virgin aggregates.
