Ways to Recycle and Reuse Concrete - The Balance Small ...

ConstructionAdvantagesBenefitsEquipmentConcrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate. Additional processes and equipment, such as water flotation, separators, and magnets, may also be used to remove specific elements from the crushed concrete. An alternative method is to pulverize the concrete, but this is not the always the best

Concrete Recycling - TU Delft

Concrete (ca 35 €/ton, 90 €/m 3) is the largest structural material in terms of volume: EU production of ready mixed concrete is about 300 million m 3 per year. At the End-of-Life phase, concrete is mainly land filled or recycled into road-based aggregate (RBA), quite often in a mix with other mineral waste materials (bricks, tiles) from the same building.
