Concrete can be recycled by grinding it up, then using screens to separate fine and coarse materials, magnets to remove steel, and water floatation to remove other unwanted materials.
How Is Concrete Recycled?
Concrete recycling is becoming an increasingly popular way to utilize aggregate materials left behind when structures or roadways are demolished.
In the past, this rubble was disposed of in landfills, but with more attention being paid to environmental concerns, concreting recycling allows reuse of the rubble while also keeping construction costs down.
The process involves breaking down the concrete, separating out any contaminants, such as metal or wood, and crushing the remaining aggregate into small pieces.
This is then sorted, often by size, and can be used as a substitute for virgin aggregate in new concrete. The first step in the concrete recycling process is to break the material down into smaller pieces.
This is done with machines that use pulverizers and crushers that break the concrete into smaller chunks. After the concrete is broken down, any contaminants, such as metal, wood, or plastic, are removed by hand or by mechanical means.
This can be done either on–site or at a recycling facility. The next step in the concrete recycling process is to sort the aggregate into various sizes.
This can be done using a variety of methods, such as sieving, screening, and air classification. Sieving separates the aggregate into various sizes by passing it through a series of screens, while
