Recycled Aggregate - California
Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.

The natural process of carbonation occurs in all concrete from the surface inward. In the process of crushing concrete to create recycled concrete aggregates, areas of the concrete that have not carbonated are exposed to atmospheric carbon dioxide. The LEED ® Green Building Rating System recognizes recycled concrete in its point system. Credit ...

Strength variation of concrete produced from recycled aggregate is higher than concrete made from natural aggregate. For the recycled aggregate concrete, it would be necessary to add more cement in concrete made with 100% of recycled aggregate in order to achieve the same workability and compression strength as conventional concrete.

Aug 18, 2020 History. Recycled concrete aggregates or Crushed concrete aggregates has been in use since the ancient times, only to be integrated with gravel, sand, and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first since crushing cured concrete proved to be much more cost-intensive in terms of labor.
