Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called
