Benefits of Using Recycled Aggregate in Concrete

Benefits of Using Recycled Aggregate: With more companies and customers becoming more environmentally conscious, pressure has risen on enterprises to utilize more sustainable materials – aggregates are a good example of this. Recycled aggregates have become a popular alternative to conventional aggregates. For example, in the UK, around 200 million tonnes of aggregates are utilized annually, and roughly 57 million tonnes of this amount are derived from recycled materials. They may be made from excess building material that has not been employed before or from previously used materials that have been reprocessed.

You may be wondering how recycling resources such as aggregates may assist you. With the cost of quarried aggregates increasing and the quality of recycled materials improving, recycled aggregates are gaining popularity as a cost-effective and handy option. Previously, leftover aggregate was disposed of in landfills; however, recycling it is now considered very useful for a variety of reasons.

What is Recycled Aggregate?

Recycled aggregates are created by reprocessing materials that were previously used in building using certain techniques. There are many types, including sand, gravel, crushed stone, and asphalt. Basically, the term “recycled aggregates” refers to previously used building materials. Reprocessing of the aggregates, which includes crushing and mixing, is then necessary to ensure they fulfill the building code requirements.

Cost effective

An important advantage of recycled aggregates is their low cost, compared to ordinary aggregates– but this does not mean you have to sacrifice quality. Recycled aggregate will be manufactured to the same exact standards as normal aggregates. Another consideration  is that if recycled aggregates were manufactured locally, transportation costs would be decreased.


Recycled aggregates are considered ecologically beneficial and critical for the building industry’s evolution and growth as it works to reduce its emissions. They are incredibly flexible due to their ability to imitate concrete and cement. Gravel mining consumes a large amount of resources and has a significant negative impact on the environment. To properly dispose of excess sand and gravel required for building, all vegetation must be removed to allow for excavating. Due to the recycling of gravel from building sites, the demand for continuing mining is reduced.


Big chunks of crushed aggregate may be utilized for a variety of bulk fill applications, as well as the foundation or fill material for drainage projects and road construction. After contaminants are removed by a selective screening and air separation process, the crushed aggregate may be utilized for a number of applications, including concrete for pavements, curbing, and bridge foundations.


The mere act of recycling the concrete contributes to sustainability by reducing landfill space; any incorporated extra material, like as metal, may also be recycled. Using this recycling technique decreases the demand for ‘virgin aggregate.’ This, in turn, mitigates the aggregate extraction operation’s effect.
