BS EN 12620:2002+A1:20085 1 Scope 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 p
30、article density greater than 2,00 Mg/m3(2 000 kg/m3) 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. !It also covers recycled aggregate with densities between 1,50 Mg/m3(1 500 kg/m3) and 2,00 Mg
31、/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 s
32、tandard 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
33、 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, th
34、e 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 danger
35、ous 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 aggr
36、egates are specified in !EN 13055-1:2002“. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated re
37、ferences, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
