scope:

This European Standard specifies the properties of 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 coarse recycled and all-in aggregate with densities between 1,50 Mg/m3 and 2,00 Mg/m3with appropriate caveats. 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 prEN 16236. Aggregates used in construction shall conform with all the requirements of the relevant European Standards for aggregates. These standards include comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates.
