Omfang

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 in conformity with EN 206-1 and concrete used in roads and other pavements and for use in precast concrete products. It covers aggregates having an oven dried particle density greater than 2,0 Mg/m3 (2000 Kg/m3). It also covers recycled aggregate with particle densities greater than 1,50 Mg/m3 (1 500 kg/m3) with appropriate caveats and recycled fine aggregate with 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 are given in EN 16236.It incorporates a general requirement that aggregates shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination.The tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for use in concrete. Categories, notes, comments etc, which are grey shaded, should not be used in concrete.Aggregates used in construction should comply with all the requirements of the relevant European Standards. 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.For materials from some other secondary sources however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as aggregates, should conform fully to this standard but may also be required to conform to specific relevant additional requirements at the place of 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 Requirements for lightweight aggregates are specified in EN 13055-1.Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use.
