Katz (2003) investigated the compressive strength of concrete which was crushed to serve as a source of aggregate for new concretes. In the investigation it can be noted that as smaller is the crushed aggregate as higher is the water absorption. Coarse aggregates among 9.54 to 25 mm had absorption of 3.3% in 28 days. Medium aggregates (2.36 to ...

Crushed concrete is exactly what it sounds, concrete ground into small pieces. After significant aging and use, concrete loses its value due to cracking, weakening and other problems. Companies acquire old concrete, crush it into small pieces and reuse it in numerous applications. Also called recycled concrete, it has many uses including bedding material for pipes and drainage systems ...

What is Recycled Concrete Aggregate? Recycled Concrete Aggregate (RCA) — also called "crushed concrete" — is made up of asphalt debris from other construction projects that can be reused to create driveways, pathways, garden beds and more.. When any concrete structure, road, sidewalk or parking lot is destroyed, that concrete is often deposited in a landfill.

The mechanical properties of conventional concrete and of concrete containing pieces of concrete from demolition waste in the place of conventional coarse aggregate were evaluated and compared. The results suggest that recycled concrete best matches the mechanical behavior of conventional concrete when the former contains recycled aggregates enriched in gravel at the expense of mortar, The ...
