Ways to Recycle and Reuse Concrete
Jan 07, 2019 How Concrete Is Recycled . Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.

Recycled Aggregates Portland Cement Association
The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete. Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required of conventional aggregates.
Spotlight on Arro Crushing for its green techniques Rock
Aug 04, 2020 By leveraging the use of recycled concrete, pits can extend the lifespan of their pit substantially, he says, adding that one customer they are crushing for has indicated that by incorporating recycled concrete they have reduced their virgin aggregate demands and extended the lifespan of their pit by more than 20 years.
Carbonation of concrete
There is, however, a greater degree of carbonation during the end-of-life stage, when concrete is crushed for reuse as an aggregate. The crushing process substantially increases the materials surface area, allowing CO2 to be more readily absorbed. Although the deconstruction and demolition process at end-of-life can be comparatively brief ...
Comparing Reinforced Concrete Pipe RCP with Plastic Pipe
Jul 22, 2009 Service life specifications for both HDPE and RCP vary throughout the United States. Some DOTs specify a 50-year service life for both products, while other agencies look for a 100-year service life for stormwater drainage pipe. It is important to remember that HDPE is a relatively new product, while concrete pipe has been in use for centuries.

Aggregate Crushing Value Test Cement Concrete
Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. If we used a weaker would get crushed under traffic loads, would produce smaller pieces not coated with a binder, and these would be easily displaced or loosened out resulting in loss of the surfacelayer.
