Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates. Removal of useless concrete from structures, buildings, road pavements etc.

How Concrete is Recycled. Concrete is recycled by using crushing equipment equipped with jaws and large impactors. Normally a secondary impactor is used and then screens are used to work with the concrete. One of these screens will be used to remove dirt and particles from concrete and the second screen will be used to remove coarse aggregate.

Recycling concrete results in significant cost savings, while also reducing the environmental footprint of concrete waste and production. Instead of mining and transporting new aggregates for concrete production, recycled concrete can be used in its place, cutting down on energy use and fuel emissions involved in sourcing and transporting other aggregates.

When recycling old concrete from a demolition, the most common procedure is the following: STEP 1: Large pieces of concrete are first crushed with special industrial equipment that uses jaws and large impactors. STEP 2: Once the concrete is broken drown, it is screened to remove any dirt or contaminating particles.
