What Is Recycled Concrete Aggregate And Their Types
Introduction of Recycled Concrete Aggregate
Concrete recycling Aggregate is the use of debris generated from the concrete structures of a demolished building. Aggregate is used most in every construction activity.
According to one estimate, the highest use of aggregate in construction was in Asia and the Pacific.
Demolition is done on a large scale to demolish the old building and build a new one based on the new requirements so that the concrete structure produces a large amount of waste.
The waste from the structure of such concrete should be dumped in a landfill as an alternative, but it can pollute the air and water. For this, the demolition of concrete was considered for the proper use of solid waste.
With the use of this construction, more and more countries have considered the importance of recycling demolition waste.
In urbanization, recycling a piece of broken concrete is done through a proper process. In this process, pieces of concrete can be selected as slabs or bricks.
Materials like waste, wood, and paper are removed from the pieces of crushed concrete. Metals such as iron are then removed using magnets and other devices.
Aggregate is separated from crushed concrete by size. The concrete aggregate is then crushed using a crushing machine. Other impurities are then removed by methods such as water flow.
Crushing the building construction site using portable crushers makes transportation cheaper. And less pollution is produced due to less transportation.
Concrete and asphalt debris can be crushed by a large road-portable plant with a capacity of 600 tons per hour.
This type of plant includes a side discharge conveyor, a screening plant, and a screen of large chunks for re-crushing large parts.
Self-contained crushers can crush a piece of concrete up to 150 tons per hour. It can make this type of crushing plant economic for small volumes.
