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 mortar, e.g.,
a) masonry mortar,
b) floor/screed mortar,
c) surfacing of internal walls (plastering mortar),
d) rendering of external walls,
e) special bedding materials,
f) repair mortar,
g) grouts,
for buildings, roads and civil engineering works.
This standard does not cover filler aggregates to be used as a constituent in cement or as other than inert filler aggregates for mortars or aggregates to be used in the surface layer of industrial floors.
It provides for the evaluation of conformity of the products to this European Standard.
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 prEN 13055-1.
