(Main)Aggregates for concrete
Aggregates for concrete
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. It also covers coarse recycled aggregate with particle densities between 1,50 Mg/m3 with appropriate caveats and recycled fine aggregate with appropriate caveats(See Annex A)
NOTE 1 Properties for lightweight aggregates are specified in EN 13055.
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 evaluation of conformity Assessment and Verification of the Constancy of Performance (AVCP) of the products to this European Standard are given in prEN 16236.
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.
NOTE 2 Categories, notes, comments etc, which are grey shaded, are not to be used in concrete.
Gesteinskornungen fur Beton
Diese Europäische Norm legt die Merkmale von Gesteinskörnungen und Füllern fest, die durch Aufbereitung natürlicher, industriell hergestellter oder rezyklierter Materialien für die Verwendung in Beton zur Verwendung im Hochbau, im Straßenbau und bei Ingenieurbauten gewonnen werden.
Sie gilt für Gesteinskörnungen mit einer Trockenrohdichte größer als 2,00 Mg/m3. Die Norm behandelt ebenfalls rezyklierte industriell hergestellte Gesteinskörnungen mit einer Rohdichte größer als 1,50 Mg/m3, wobei entsprechende Vorbehalte gelten (siehe Anhang A). Die Bewertung der Dichte rezyklierter Gesteinskörnungen erfolgt üblicherweise an groben Fraktionen.
ANMERKUNG 1 Zu Festlegungen von leichten Gesteinskörnungen siehe EN 13055.
Der Einsatz von Gesteinskörnungen als Boden wird in dieser Norm nicht behandelt.
ANMERKUNG 2 Wegen der großen Unterschiede in den geologischen und pedologischen Gegebenheiten in Europa können genaue Definitionen zu Böden jenen Dokumenten entnommen werden, die sich mit ihrer Verwendung am jeweiligen Einsatzort befassen.
Anhang A (normativ) enthält eine Liste von betrachteten Ausgangsstoffen, die in den Anwendungsbereich der Norm fallen.
Festlegungen hinsichtlich der Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) von Gesteinskörnungen nach dieser Norm sind in FprEN 16236 zu finden.
Gesteinskörnungen für die Verwendung im Bauwesen müssen alle Anforderungen der einschlägigen Europäischen Normen zu Gesteinskörnungen erfüllen. Diese Normen legen allgemeine und besondere Anforderungen an natürliche Gesteinskörnungen, industriell hergestellte Gesteinskörnungen und rezyklierte Gesteinskörnungen, wie beispielsweise das Ausdehnungsverhalten bestimmter Schlacken und die Zusammensetzung rezyklierter Gesteinskörnungen, fest.
Granulats pour béton
La présente Norme européenne spécifie les caractéristiques des granulats et fillers, élaborés à partir de matériaux naturels, artificiels ou recyclés et des mélanges de ces granulats destinés à être utilisés dans la fabrication du béton, et dans les travaux de constructions de bâtiments, de routes et de génie civil.
Elle s'applique aux granulats dont la masse volumique réelle des particules séchées à l’étuve est supérieure à 2,00 Mg/m3. Elle s'applique également aux gravillons recyclés et artificiels dont la masse volumique réelle est supérieure à 1,50 Mg/m3, avec les mises en garde appropriées (voir Annexe A). L’évaluation de la densité des granulats recyclés est typiquement effectuée sur les gravillons.
NOTE 1 Les propriétés des granulats légers sont spécifiées dans l’EN 13055.
L’utilisation des granulats en tant que sols n’est pas couverte par cette norme.
NOTE 2 En raison de l’importante variabilité des conditions géologiques et pédologiques en Europe, la définition précise du sol peut être trouvée dans les documents relatifs à l’application sur le lieu d’utilisation
Une liste des origines des matériaux qui ont été prises en considération et relèvent du domaine d'application de la présente norme est donnée en Annexe A (normative).
Les exigences relatives à l’Evaluation et la Vérification de la Constance des Performances (EVCP) des produits de cette norme européenne sont spécifiées dans le FprEN 16236.
Les granulats utilisés dans la construction doivent respecter toutes les exigences des Normes européennes concernées pour les granulats. Ces dernières contiennent les exigences générales et particulières relatives aux granulats naturels, artificiels et recyclés, et traitent par exemple de l'expansion de certains laitiers et de la composition des granulats recyclés.

Foreword
This document (prEN 12620:2015) has been prepared by Technical Committee CEN/TC 154
“Aggregates”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12620:2002+A1:2008.
This European Standard has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
Construction Products Regulation (EU) No. 305/2011.
For relationship with EU Regulation(s), see informative Annex ZA, which is an integral part of this
document.
The most significant technical changes compared to the previous edition include:
a) Harmonisation of vocabulary and Annex ZA to be consistent with Construction Products
Regulations;
b) Unification of categories which are common across the four main aggregate standards:
EN 12620, EN 13043, EN 13139 and EN 13242;
c) Description of assessment and verification of conformity of performance of aggregates (AVCP) -
type testing and factory production control in a separate new standard prEN 16236;
d) Implementing general sentences on dangerous substances and adding a new normative Annex A
dealing with all source materials considered;
e) Unification of definitions which are common across the four main aggregate standards:
EN 12620, EN 13043, EN 13139 and EN 13242, i.e. for coarse, fine, all-in aggregates and
natural graded 0/8 aggregates;
f) Adding categories for the sand equivalent value for fines quality;
g) Adding categories for the methylene blue value for fines quality;
h) Adding the categories for maximium Micro-Deval, angularity and water suction height
Inserting a new clause “General Requirements”
In this document the wordings ‘property and characteristic’ have the same meaning
Requirements for assessment and verification of constancy of performance are given in prEN 16236.
Requirements for other end uses of aggregates are specified in the following European Standards:
— EN 13043, Aggregates for bituminous mixtures and surface treatments for roads, airfields and
other trafficked areas;
— EN 13055, Lightweight aggregates;
— EN 13139, Aggregates for mortar;

Note: Due to fact that the EC has not yet been able to confirm the financial commitment for the New
Approach Consultants’ work in 2015, there are currently no New Approach Consultants in place for
2015. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met.
This shall not prevent the processing of draft standards nor the offering of harmonized standards to
the European Commission. In particular, draft standards can be sent to vote without Consultant
assessment.
This note will be removed from the Foreword of the finalized publication.

4 General requirements
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. Categories, NOTES, comments etc.,
which are grey shaded, are not used for aggregates for concrete.
NOTE Guidance on selection of appropriate categories for specific applications can be found in national
provisions in the place of use of the aggregate.
Where conformity with a category is based on a value of a property being less than or equal to a
given value, conformity with a more severe category (lower value) automatically confers conformity
with all less severe categories (higher values). Similarly for categories based on the value of a
property b
