Inert solid waste is concrete, asphalt, dirt, brick, and other rubble. Portland cement concrete (PCC) and asphalt concrete (AC) consist primarily of aggregate. The cement and asphalt serve as binders. Some PCC contains steel reinforcement bars, or "rebar," such as a bridge deck or tilt-up slabs.
Recycled Concrete Aggregates or Crushed Concrete Aggregates are Manufactured from Demolished Concrete by Concrete Recycling Process.
Dec 29, 2017 · The largest part of C&D material is concrete, which encompasses around 70 percent of C&D generated material before recycling, according to the U.S. EPA. Construction (21.7 million tons) and demolition (353.6 million tons) activities accounted for over 375 million tons of material in total.

For these LEED programs, Materials and Resources Credit 4: Recycled Content allows up to two LEED certification points for using materials with recycled content. The inert nature of concrete masonry lends itself well to incorporating recycled materials as cement replacements, as aggregates and as other constituents in the concrete mix.
Recycled concrete aggregate (RCA) is concrete and other materials like pavement that is crushed into aggregate and good enough to be used as fill material and compactable fill. As landfills across the country begin to fill up and refuse broken concrete, the need to recycle concrete into a usable material became necessary.
For materials contain cement, it is important to take the density test immediately after compaction. When taken later after some hydration has occurred, the density values tend to go down. I've seen this in soil-cement, crushed recycled concrete, and cement-treated base materials. This is particularly true when a nuclear density gage is used.
