CEN/TC 154/SC 1 - Aggregates for mortars

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 particle 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/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 standard 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 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 co

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   The requirements in this European Standard are based upon experience with aggregate types with an established pattern of use.  Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g., recycled aggregates and aggregates arising from certain industrial by-products.  Such aggregates, which should comply with all the requirements of this European Standard, could have other characteristics not included in Mandate M 125 that do not apply to the generality of aggregates types with an established pattern of use and when required, provisions valid at the place of use can be used to assess their suitability.
NOTE 2   Properties for lightweight aggregates are specified in prEN 13055-1.

TC - Change in Scope and Annex ZA

This document 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.
NOTE 1   Assessment of the density of recycled aggregates is typically carried out on coarse fractions.
NOTE 2   Lightweight aggregates are specified in EN 13055.
Assessment and Verification of Constancy of Performance (AVCP) of aggregates to this document are given in EN 16236.
Aggregates used in construction are meant to comply with all the relevant European standards for aggregates. These standards include comprehensive and specific provisions 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).

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.
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.
It covers aggregates having an oven dried particle density greater than 1,50 Mg/m3 (2 000 kg/m3). It also covers recycled aggregate with densities between 1,50 Mg/m3 (1 500 kg/m3) and 2,00 Mg/m3 (2 000 kg/m3).
A list of the source materials that have been considered and are within the scope of this standard is given in Annex A (normative)
Requirements for the evaluation of conformity of the products to this European Standard are given in FprEN 16236.
It incorporates a general requirement that aggregates will 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 (see Note 3).
The Tables in this standard include categories that 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 mortars, renders and screeds. Those categories, which are appropriate for mortar, are shown grey shaded.
NOTE 1   Aggregates used in construction should comply with all the relevant requirements of the appropriate 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.
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, will comply fully with this standard but may also be required to comply with 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 2   Properties for lightweight aggregates are specified in EN 13055-1.
NOTE 3    Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalized, attention should be paid to requirements at the place of use.
