Concrete Aggregate
Recycled Concrete
Recycled concrete is old concrete that's been broken up and crushed back down to gravel size. It comes from torn-out sidewalks, driveways, and building slabs. The pieces are angular, with bits of the original rock still visible under a coating of hardened cement paste. That paste makes it a little lighter than fresh crushed stone, but it still packs down hard.
You'll see it sold two ways. Plain crushed concrete is a general mix that's good for fill and rough driveways. The #610 grade follows a dense-graded blend from about 1 inch down to fines, so it locks up tight under pavers, sheds, and new driveways. It usually runs 30 to 50 percent less than virgin road base since the rock's already been mined once.

How to choose within recycled concrete
Match the mix design
Batch plants and ready-mix trucks work to a spec. Confirm the size and gradation the plant is running before you order.
Coarse vs. fine
Coarse aggregate gives the mix its strength; fine aggregate fills the gaps. A slab needs both — usually delivered separately and blended at the plant.
Cleanliness matters
Fines and clay contamination weaken the cure. If a load looks dusty, ask for a wash spec sheet before you take delivery.
