(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 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.
Gesteinskörnungen für Beton
Diese Europäische Norm legt die Eigenschaften von Gesteinskörnungen und Füllern fest, die durch Aufbereitung natürlicher, industriell hergestellter oder rezyklierter Materialien und Mischungen daraus für die Verwendung in Beton nach EN 206 1 und in Beton zur Verwendung in Straßen, anderen Deckschichten und in Betonfertigteilen gewonnen werden.
Sie deckt Gesteinskörnungen mit einer Kornrohdichte nach Trocknung im Wärmeschrank größer als 2,00 Mg/m3 (2 000 kg/m3) ab. Die Norm deckt ebenfalls rezyklierte Gesteinskörnungen mit einer Rohdichte größer als 1,50 Mg/m3 (1 500 kg/m3) und rezyklierte feine Gesteinskörnungen ab, jeweils mit den entsprechenden Einschränkungen.
Anhang A (normativ) enthält ein Verzeichnis der berücksichtigten Ausgangsmaterialien, die im Anwen-dungsbereich dieser Europäischen Norm liegen.
Anforderungen an die Bewertung der Konformität von Produkten nach dieser Europäischen Norm sind in EN 16236 enthalten.
Die Norm enthält die allgemeine Anforderung, dass die Freisetzung gefährlicher Stoffe aus Gesteinskörnungen die maximal zulässigen Grenzwerte, die in der einschlägigen Europäischen Norm für das Material festgelegt sind bzw. die nach den nationalen Bestimmungen des Bestimmungsmitgliedstaats zulässig sind, nicht übersteigen darf.
Die Tabellen in dieser Norm enthalten Kategorien, die in allen vier Hauptnormen für Gesteinskörnungen festgelegt sind: EN 12620, EN 13043, EN 13139 und EN 13242. Nicht alle Kategorien sind für Gesteinskörnungen zur Verwendung in Beton geeignet.
Die grau hinterlegten Kategorien, Anmerkungen, Kommentare, usw. sollten nicht für Gesteinskörnungen in Beton verwendet werden.
Gesteinskörnungen im Bauwesen sollten mit allen einschlägigen Anforderungen der jeweiligen Europäischen Normen für Gesteinskörnungen übereinstimmen. Diese Normen enthalten umfassende und spezifische Anforderungen an natürliche Gesteinskörnungen, Hochofenstück- und Stahlwerksschlacken und rezyklierte Gesteinskörnungen, die sich zum Beispiel mit der Raumbeständigkeit bestimmter Basalte, der Volumenzunahme bestimmter Schlacken und der Zusammensetzung von rezyklierten Gesteinskörnungen befassen.
Die Arbeiten an Festlegungen für Materialien aus weiteren sekundären Quellen sind jedoch noch nicht abgeschlossen und die Anforderungen sind unvollständig. In der Zwischenzeit sollten solche Materialien, sofern sie als Gesteinskörnungen in Verkehr gebracht werden, den Anforderungen dieser Norm voll entsprechen. Unter Umständen müssen sie aber auch zusätzliche spezifische Anforderungen, die am Verwendungsort gelten, erfüllen. Abhängig von den Erfahrungen mit der Anwendung des Produkts dürfen im Einzelfall zusätzliche Eigenschaften und Anforderungen festgelegt werden und in den spezifischen Vertragsunterlagen definiert werden.
ANMERKUNG Anforderungen an leichte Gesteinskörnungen sind in prEN 13055 festgelegt.
Zurzeit werden Anforderungen an die Angabe des Potenzials von Gesteinskörnungen, gesetzlich geregelte gefährliche Stoffe freizusetzen, erarbeitet. Bis zur Fertigstellung dieser Anforderungen sollten die Anforderungen am Verwendungsort beachtet werden.
Granulats pour béton
La présente Norme européenne spécifie les caractéristiques des granulats, y compris celles des fillers, élaborés à partir de matériaux naturels, artificiels ou recyclés et des mélanges de ces granulats destinés à être utilisés dans la fabrication :
- des bétons selon les prescriptions de l'EN 206-1
- des bétons utilisés dans la construction des routes et chaussées,
- des produits préfabriqués en béton.
Elle s'applique aux granulats dont la masse volumique réelle des particules séchées à l’étuve est supérieure à 2,00 Mg/m3 (2 000 kg/m3). Elle s'applique également aux granulats recyclés dont la masse volumique réelle est supérieure à 1,50 Mg/m3 (1 500 kg/m3), avec les mises en garde appropriées, ainsi qu’au sable recyclé, avec les mises en garde appropriées.
Une liste des origines des matériaux qui ont été prises en considération et relèvent du domaine d'application de la présente norme est donnée à l'Annexe A (normative).
Les exigences relatives à l’évaluation de la conformité sont spécifiées dans l’EN 16236.
La présente norme intègre une exigence générale stipulant que les granulats ne doivent dégager aucune substance dangereuse dont les valeurs d'émission dépassent les niveaux maximaux admissibles spécifiés dans une Norme européenne pertinente pour le matériau ou dans la réglementation nationale de l'Etat membre de destination.
Les tableaux de la présente norme contiennent des catégories qui sont communes aux quatre principales normes relatives aux granulats : EN 12620, EN 13043, EN 13139 et EN 13242. Ces catégories ne sont pas toutes appropriées pour un usage des granulats dans les bétons.
Les catégories, notes, commentaires, etc. qui sont grisés ne devraient pas être utilisées pour les applications dans les bétons.
Les granulats utilisés dans la construction doivent respecter toutes les exigences des Normes européennes concernées. Ces dernières contiennent les exigences générales et particulières relatives aux granulats naturels, au laitier de haut fourneau et d'aciérie et aux granulats recyclés, et traitent par exemple de la stabilité de certains basaltes, de l'expansion de certains laitiers et de la composition des granulats recyclés.
Cependant, pour les matériaux provenant d’autres sources secondaires, les travaux sont en cours et les exigences sont incomplètes. En attendant, il convient que ces matériaux, lorsqu'ils sont mis sur le marché en tant que granulats, respectent pleinement la présente norme, mais ils peuvent aussi devoir se conformer à des exigences complémentaires spécifiques pertinentes sur le lieu d'utilisation. Des caractéristiques et des exigences complémentaires peuvent être spécifiées au cas par cas, en fonction de l'expérience acquise à l'usage du produit, et définies dans des documents contractuels spécifiques.
NOTE Les caractéristiques des granulats légers sont spécifiées dans le prEN 13055.
Les exigences relatives à la déclaration du potentiel des granulats à relarguer des substances dangereuses réglementées sont actuellement en cours d'élaboration. Tant qu'elles ne sont pas finalisées, il convient de tenir compte des exigences en vigueur sur le lieu d'utilisation.

4.1 General The necessity for testing and declaring all properties specified in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the aggregates shall be tested as specified in Clause 4 to determine the relevant geometrical properties. When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g. a value of, say, 55 for the flakiness index corresponds to FI55 (Declared Value). NOTE 1 When a property is not required, a “No requirement” category can be used. SIST EN 12620:2013
Categories, notes, comments etc, which are grey shaded, should not be used in concrete. 4.2 Aggregate sizes All aggregates shall be described in terms of aggregate sizes using the designations d/D, and shall conform to the grading requirements specified in 4.3, except for aggregates added as fillers which shall be specified as filler aggregate. Aggregate sizes shall be described by the pair of sieve sizes in millimetres selected from the basic set, or the basic set plus set 1, or the basic set plus set 2 in Table 1 with d as the lower limit designation and D as the upper limit designation sieve between which most of the particle size distribution lies, (e.g. 0/4mm, 0/2mm, 2/4mm etc.). A combination of sizes from set 1 and set 2 is not permissible. Aggregate sizes shall have D/d not less than 1,4. SIST EN 12620:2013

4.3 Grading 4.3.1 General The grading of the aggregate, when determined in accordance with EN 933-1, shall conform to the requirements of 4.3.2 to 4.3.5 as appropriate to its aggregate size d/D. Aggregates may comprise single sizes, all-in aggregates or combinations of two or more than two sizes. Aggregates supplied as a mixture of different sizes or types should be uniformly blended. When aggregates of significantly different density are blended, caution is necessary to avoid segregation. When assessing aggregates within a system of factory production control, at least 90% of gradings, taken on different batches, within a maximum period of six months, shall fall within the limits specified in Tables 2 to 5 for tolerances on manufacturer declared typical gradings. Size designations and grading categories are essentially categories of convenience and different sizes and grading categories may be used by agreement between supplier and purchaser. Where the specification requires the use of sieves which are a fraction or a multiple of the upper sieve size (eg D/2 or D/1,4 or 1,4D; 2D) the sieve chosen shall be the next nearest from basic set plus set 1 or basic set plus set 2. When a sieve size of the ISO 565 R20 series is closer to the calculated d/2, D/1,4 D/2 size, the manufacturer may choose to use this R20 size; SIST EN 12620:2013

Frequently Asked Questions
EN 12620:2013 is a standard published by the European Committee for Standardization (CEN). Its full title is "Aggregates for concrete". This standard covers: 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.
