Aggregates contribute to sustainability agenda

MILTON KEYNES: Aggregates are increasingly contributing to the sustainability agenda, according to the NHBC Foundation.
The use of recycled and secondary materials as aggregates in residential construction is increasing across the UK, with current estimates at 21% and 3% respectively.
While the use of recycled materials is currently seven times higher, availability of secondary materials is expected to increase and the imbalance looks set to change.
As a follow-up to the two-part BRE DG522 guide 'Hardcore for Supporting Ground Floors of Buildings' sponsored by NHBC and published in 2011, the NHBC Foundation has published 'The Use of Recycled and Secondary Materials in Residential Construction'.
This new and guide provides an overview for specifiers, builders and developers into the two types of materials, their sources, availability, and applications.
There are a number of potential advantages to the industry of using recycled and Graham Perrior, head of standards and technical at NHBC, commented: "The UK currently uses more recycled and secondary aggregate than any other EU country, and their use is predicted to increase in coming years.
"The use of these materials has solid environmental benefits through resource efficiency, as well as potential cost savings by reducing reliance on landfill to dispose of old materials."
