More recently another type of aggregate has emerged: recycled concrete aggregate (RCA) which is produced by crushing concrete reclaimed from concrete buildings, slabs, bridge decks, demolished highways, and other structures.
Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod.

But one enterprising company, Jean-Jacques Perhirin, in Kéranchas, recently bought two Crusher''s units - a BF70.2 crushing bucket and an -S14 screening bucket - and began recycling debris. The two powerful units now work close to another powerful unit, the 53m-high Phare du Créac''h.
The practical use of recycled concrete aggregate produced by crushing concrete waste reduces the consumption of natural aggregate and the amount of concrete waste that ends up in landfills. This study investigated two methods used in the production of fine recycled concrete aggregate: (1) a method that produces fine as well as coarse aggregate, and (2) a method that produces only fine ...

Construction aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined material in the world. Aggregates are a component of composite materials such as concrete and asphalt ...
Degradation and crushing of aggregates such as RCA are significant for geotechnical and pavement applications (Saberian et al., 2020a). Therefore, Los Angeles abrasion test (AS 1141.23, 2009) and aggregate crushing value test (AS 1141.21, 1997) were also
In the crushing business, having the right equipment is crucial to ensuring you are maximizing profit and minimizing costs. For crushing operators who work in a pit context, pea-sized natural rounds and fines are inevitable and must be eliminated to meet aggregate
Shi et al. (2019) reported an increase in individual crushing strength of carbonated CWP aggregate when cement was added. Gunning et al. (2011b) also found that the aggregate strength and CO 2 uptake increased with the addition of reactive binders, such as

· Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
