Shear strength of recycled aggregate concrete is lesser than of normal concrete. This is because the recycled aggregate from fielddemolished concrete for example can be relatively weaker than a typical natural aggregate. In general, there is a 10% decrease in strength when recycled coarse aggregates are used. Uses of Crushed Concrete Aggregates

Recycled concrete qualifies for recycled material credits, and because it usually is found locally, it qualifies for local credits. • Concrete with recycled concrete aggregate has a smaller carbon footprint. • Crushing old concrete to produce aggregate takes less energy than mining aggregate.
Recycled Aggregates and Base Aggregates consist of hard, graduated fragments of inert mineral materials, including sand, gravel, crushed stone, slag, rock dust, or powder. Portland cement concrete (PCC) and asphalt concrete (AC) consist primarily of aggregate, with the
recycled aggregates of various particle size groups, while the crushing age had almost no effect. The properties of the concrete made with recycled aggregates were inferior to those of concrete made with aggregates.

Recycling of concrete is a relatively simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. See ACI 555 (2001) for more information on processing old concrete into recycled concrete aggregates.
Aggregate may be natural, manufactured or recycled. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of
