Aggregain promotes use of recycled aggregates in concrete

Summary

AggRegain, the recently launched free web-based information service, designed to assist anyone interested in specifying, purchasing or supplying recycled or secondary aggregates has issued new guidance and information on the use of recycled aggregates in concrete.

Current Standards

The current British Standard for concrete ( BS 5328 ) is due to be replaced by the European Standard BS EN 206 and its complementary standard British Standard BS 8500 in December 2003. The new European and British Standards will allow the use of recycled aggregates and recycled concrete aggregate in the production of concrete.
In advance of these changes, Aggregain is seeking to raise awareness of the potential use of these materials and air-cooled blast furnace slag in place of primary aggregates in low strength concrete for use in housing developments.
Technical notes, purchase order details and a case study showing savings of at least £2 per tonne where recycled concrete aggregate replaced primary material in the construction of a concrete access road can be found on the website. In addition, a list of frequently asked questions on the changes in the standards and the use of recycled and secondary aggregates in concrete produced by Dr Bill Price of the British Cement Association is available via AggRegain.
