This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural,
manufactured or recycled materials and mixtures of these aggregates for use in concrete. It covers aggregates
having an oven dried particle density greater than 2,00 Mg/m3 (2 000 kg/ms) for all concrete, including concrete in
conformity with EN 206-1 and concrete used in roads and other pavements and for use in precast concrete products.
ID It also covers recycled aggregate with densities between 1,50 Mg/m3 (1 500 kg/m3) and 2,00 Mg/m3
(2 000 kg/m3) with appropriate caveats and recycled fine aggregate (4 mm) with appropriate caveats.
It also specifies that a quality control system is in place for use in factory production control and it provides for the
evaluation of conformity of the products to this European Standard.
This standard does not cover filler aggregates to be used as a constituent in cement or as other than inert filler
aggregates for concrete.
NOTE 1 Aggregates used in construction should comply with all the requirements of this European Standard. As well as
familiar and traditional natural and manufactured aggregates Mandate M/125 "Aggregates" included recycled aggregates and
some materials from new or unfamiliar sources. Recycled aggregates are included in the standards and new test methods for
them are at an advanced stage of preparation. For unfamiliar materials from secondary sources, however, the work on
standardisation has only started recently and more time is needed to define clearly the origins and characteristics of these
materials. In the meantime such unfamiliar materials when placed on the market as aggregates must comply fully with this
standard and national regulations for dangerous substances (see Annex ZA of the standard) depending upon their intended
use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use
of the product, and defined in specific contractual documents.
NOTE 2 Properties for lightweight aggregates are specified in EN 13055-1:2002.
