ORIGINAL ARTICLE Performance of concrete made with aggregates recycled from precasting industry waste: inﬂuence of the crushing process D. Pedro • J. de Brito • L. Evangelista
A three-stage crushing cycle for a recycled aggregate, with surface crushing, mortar crushing, and natural aggregate crushing, is proposed. This cycle was repeated several times, depending on the number of natural aggregates within each sample.

This chapter discusses the total process of aggregate production from extraction through processing. Also discussed is the handling, stockpiling, and shipping of the product up to the point where the material leaves the Producer's control. Processing influences mineral quality and integrity, aggregate physical properties, and, in particular, gradation (size control). Establishing a stable ...

Recycled aggregate is produced by crushing concrete, and sometimes asphalt, to reclaim the aggregate. Recycled aggregate can be used for many purposes. The primary market is road base. For information on recycling asphalt pavement into new asphalt pavement. See Asphalt Pavement Recycling.
Abstract: with the accelerating urbanization process, urban transformation and the rapid development of construction industry, concrete as cement, sand, pebbles and gravel, the biggest consumers of natural resources, global concrete industry is now at an annual rate of about 8 billion tons of consumption of natural aggregate.
When structures made of concrete are demolished or renovated, concrete recycling is an increasingly common method of utilizing the rubble. Concrete was once routinely trucked to landfills for disposal, but recycling has a number of benefits that have made it a more attractive option in this age of greater environmental awareness, more ...
Plastic Concrete: Building Bricks Made From Landfill . Using recycled materials is so hot right now, but using them as aggregate is hotter than Hansel in a black shirt on a summer Sunday.
For the purpose of this article the term crushed concrete aggregate (CCA) is defined as returned concrete and recycled concrete aggregate clean enough to be used as aggregate for new concrete. Recycled concrete aggregate (RCA) refers to crushed concrete and other materials suitable for use as fill and compactible fill.

Recycling concrete is a process of breaking, removing and crushing it from its current location. It is then re-created to be good as new. It is often the best option for concrete removal. Even just a slab of concrete doesn't make any difference all recycled concrete is aggregated for using subbase material. It can also be paired with new and pure materials.
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.
