This European Standard specifies the characteristics of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in mortars, renders and screeds, e.g. masonry mortar, floor/screed mortar, surfacing of internal walls (plastering mortar), rendering of external walls, special bedding materials, repair mortar and grouts for buildings, roads and civil engineering works. It covers aggregates having an oven-dried particle density greater than 2,00 Mg/m3 . It also covers recycled and manufactured aggregate with particle densities greater than 1,50 Mg/m3 with appropriate caveats (See Annex A). Assessment of the density of recycled aggregates is typically carried out on coarse fractions. NOTE 1 Properties for lightweight aggregates are specified in EN 13055. The use of aggregates as soil is not covered by this standard. NOTE 2 due to huge variation of geological and pedological conditions in Europe, precise definition of soil can be found in the documents related to the application at the place of use. A list of the source materials that have been considered and indicating those which are within the scope of this standard is given in Annex A (normative). Requirements for the Assessment and Verification of the Constancy of Performance (AVCP) of aggregates to this European Standard are given in FprEN 16236. Aggregates used in construction are meant to comply with all the requirements of the relevant European Standards for aggregates. These standards include comprehensive and specific requirements for natural aggregates, manufactured aggregates and recycled aggregates, dealing with, for example, the volume stability and loss of ignition of certain manufactured aggregates (slag, fly ash).
