Recycled aggregate production in the UK Recycled aggregate in the UK is defined as aggregate resulting from the processing of inorganic material previously used in construction. To ensure the aggregate is inert, it is manufactured from material tested and characterized under European Waste Codes. @HASSAN HARRAZ 2017 AGGREGATE STONES 8 9.
The Effect of Aggregate Properties on Concrete
Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. Most natural sands and gravel from riverbeds or seashores are smooth and rounded and are excellent aggregates. Crushed stone produces much more angular and elongated aggregates, which have a higher surface-to-volume ratio, better bond characteristics but require more

An important local 'downstream' industry is that of concrete product (blocks, pipes, kerbs, pavers, etc) with operations for example at Callow Rock, Mells, Torr Works, Holcombe, Wells and Cheddar. Not only do these produce 'added value' to the raw aggregate, they often make use of 'fines' which are a by-product of general aggregate processing, and without this market would often have to be dumped.
