Recycled Aggregate

Recycled Aggregate Types

Recycled aggregate is made from crushing materials from demolition sites. Recycled aggregate is a viable source and has been used successfully in granular sub-bases, soil-cement, and in new concrete production.

Recycled concrete aggregate is classified as either:

Recycled Aggregate (RA), or as
Recycled Concrete Aggregate (RCA).

Recycled aggregate (RA) includes concrete and brick

Recycled concrete aggregate is 95% concrete and only 5% of brick. Clean concrete from slabs, floors and concrete frames are separated away from brick materials to give a clean concrete aggregate for this classification.

Because RCA is a cleaner material, there are fewer restrictions for its use to produce new concrete from it. The application for RCA is given in the British standard BS 8500-2.

Recycled Concrete Aggregate (RCA)

With the growing awareness of the environment and recycling, there is no evidence that no hard demolition material is being sent to landfill.

At the moment, 75/80% of secondary and recycled aggregates are used for sub-base and fill. The remainder is being used to make new concrete.

Due to the profitability of using the aggregate in concrete the percentages above will change.

Recycled concrete is used as the coarse portion of the aggregates in the concrete mix. The concrete is crushed to 40/20mm. in size. When using recycled concrete in new concrete the following should be considered:

Recycled concrete as aggregate will typically have higher absorption and lower specific gravity than natural aggregate and will produce concrete with slightly higher drying shrinkage and creep.

These differences become more significant with increasing amounts of recycled fine aggregates.

Our Recommendation for Recycled Aggregate

Understanding concrete aggregate and, concrete design is a specialist subject. We would recommend that you speak to a concrete technologist to design your mixes or to adjust your current mixes if you think they can be improved.

You can speak to one of our recommended concrete technologists by request. Either complete the contact us form on our contact us page or text Bob Evans. His details are below.

How To Take Advantage of Recycled Aggregate

With a large amount of crushed concrete and aggregates on a construction site, you can make your own concrete rather than buy in ready-mix.

The difference in price in the UK is €30 per m3

The Hackney site above produced 2,680 tonnes of aggregate. If 50% of this was used to make concrete the volume would be around 1,000m3 depending on the mix and use of quarried materials. The saving or profit would be around €30,000

Fibo Intercon manufactures a range of mobile batching plant including 15, 30, 45 m3/hr output.

For a 8 hour shift the plant can produce between 100 to 300 m3 of concrete per day. With a difference of €30 m3 the profit earned can be between €3,000 to €9,000 per day.

The plant is mobile and can be moved from site to site maximising productivity and utilisation.
