Armourstone - Part 1: Specification
This European Standard specifies the properties of aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these materials for use as armourstone.
Wasserbausteine - Teil 1: Anforderungen
Diese Europäische Norm legt die Eigenschaften von Gesteinskörnungen fest, die durch Aufbereitung natürlicher, künstlicher industriell hergestellter oder recycelter rezyklierter Materialien und Mischungen dieser Materialien gewonnen und als Wasserbausteine verwendet werden.
Sie enthält Festlegungen für die Bewertung der Konformität von Produkten nach dieser Europäischen Norm.
ANMERKUNG 1 Wasserbausteine für das Bauwesen sollten sämtlichen Anforderungen dieser Europäischen Norm genügen. Neben den bekannten und traditionellen natürlichen und industriell hergestellten GesteinskörnungenWasserbausteinen sind rezyklierte Gesteinskörnungen Wasserbausteine sowie einige Rohstoffe aus Vorkommen, über die noch keine oder nur wenige Erfahrungen vorliegen, im Mandat M/125 „Gesteinskörnungen" aufgeführt. Rezyklierte Gesteinskörnungen Wasserbausteine sind in den Normen enthalten und die entsprechenden neuen Prüfverfahren sollen bald vorliegen. Mit den Normungsarbeiten für Sekundärrohstoffe, zu denen erst wenige Erfahrungen vorliegen, wurde jedoch erst vor kurzer Zeit begonnen. Mehr Zeit wird benötigt, um die Herkunft und die Eigenschaften dieser Rohstoffe eindeutig festzulegen. In der Zwischenzeit müssen solche Rohstoffe, die als GesteinskörnungenWasserbausteine auf den Markt gebracht werden, sämtliche Anforderungen dieser Norm erfüllen sowie abhängig vom vorgesehenen Verwendungszweck den entsprechenden nationalen Vorschriften über gefährliche Substanzen (siehe Anhang ZA dieser Norm) genügen. Im Einzelfall können zusätzliche Eigenschaften und Anforderungen abhängig von den Erfahrungen bei der Anwendung des Produktes festgelegt werden sowie in besonderen vertraglichen Vereinbarungen definiert werden.
ANMERKUNG 2 In Wasserbauwerken werden feinere als die in dieser Europäischen Norm festgelegten Gesteinskörnungen verwendet. Bei derartigen Gesteinskörnungen sollten die für andere Endanwendungen Verwendungszwecke geltenden
Enrochements - Partie 1: Spécifications
La présente Norme européenne spécifie les caractéristiques des granulats naturels, artificiels et recyclés ou les
mélanges de ces granulats destinés à être utilisés comme enrochement.
Elle fournit les règles d'évaluation de la conformité des matériaux aux critères de la présente Norme européenne.
NOTE 1 Il convient que les enrochements utilisés dans la construction soient conformes à toutes les exigences de la
présente Norme européenne. Le mandat M/125 traite, outre des enrochements courants et traditionnels naturels et
artificiels, des enrochements recyclés ainsi que de certains matériaux d’origine nouvelle ou moins courante. Les
enrochements recyclés sont inclus dans les normes et de nouvelles méthodes d’essai, à un stade avancé d’élaboration,
leur sont destinées. Le travail de normalisation ne fait en revanche que commencer pour les matériaux moins courants de
source secondaire et davantage de temps est nécessaire pour définir clairement l’origine et les caractéristiques de ces
matériaux. Dans l’intervalle, ces matériaux moins courants, s’ils sont mis sur le marché, doivent respecter pleinement la
présente norme et les réglementations nationales relatives aux substances dangereuses (voir l’Annexe ZA de la norme)
selon l’usage qui leur est destiné. Des caractéristiques et des prescriptions 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 2 Des granulats plus petits que ceux spécifiés dans la présente Norme européenne sont utilisés dans les
ouvrages hydrauliques. Dans ce cas, il convient d'appliquer les Normes européennes « granulats » pour d'autres usages.

EN 13383-1:2013 (E) 3 Foreword This document (EN 13383-1:2013) has been prepared by Technical Committee CEN /TC 154, "Aggregates", the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn at the latest by February 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13381-1:2002. The most significant technical changes that have been made include: the removal of the previous minimum density requirement and a change in the method of declaring density; inclusion of a new coarse grading (32/90mm) and a new light grading (15 kg to 120 kg) and guidance on the declaration of non-standard heavy gradings; inclusion of a new category for resistance to wear MDE15, to take account of the fact that very few armourstone sources meet the highest quality category MDE10; requirements for sample preparation for the Micro-Deval test has been moved from EN 13383-1 to
EN 13383-2. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Requirements for initial type testing and factory production control (previously specified in a normative annex to this standard) are now given in a new standard EN 16236: on Evaluation of conformity of aggregates. EN 13383 Armourstone consists of the following parts: Part 1: Specifications Part 2: Test methods Requirements for other end uses of aggregates are specified in the following European Standards: EN 12620 Aggregates for concrete EN 13043 Aggregates for bituminous mixtures and surface dressings for roads, airfields and other trafficked areas EN 13055 Lightweight aggregates EN 13139 Aggregates for mortar EN 13242 Aggregates for unbound and hydraulically bound materials for use in civil engineering work and road
construction EN 13450 Aggregates for railway ballast According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13383-1:2013 (E) 4 1 Scope This European Standard specifies the properties of aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these materials for use as armourstone. A list of the source materials that have been considered and are within the scope of this European Standard is given in Annex A (normative). Requirements for the evaluation of conformity of the products to this European Standard are given in EN 16236. It incorporates a general requirement that armourstone 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. Armourstone used in construction should comply with all the requirements of this European Standard. The standard includes specific requirements for natural armourstone, ferrous and steel making slag and recycled armourstone. 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 armourstone, should comply fully with this European 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. Finer aggregates than specified in this European Standard are used in hydraulic structures. For such aggregates European Standards for other end uses of aggregates should be applied. Requirements for the declaration of the potential of armourstone 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

When required, the tests specified in Clause 4 shall be carried out to determine appropriate geometrical properties. When the value of a property is required but not defined by specified limits the value should be declared by the producer as an XXDeclared category, e.g. in Table 7 the percentage by number of pieces of armourstone with less than 50 % crushed or broken surfaces of say 7 corresponds to RO7. When a property is not required, a “No requirement” category may be used. Guidance on selection of appropriate categories for specific applications may be found in national provisions in the place of use of the armourstone. NOTE 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 property being greater than or equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all less severe categories (lower values). Sampling shall be carried out as specified in EN 13383-2:2013, Clause 4. 4.2 Gradings 4.2.1 Coarse gradings The particle size distribution of coarse gradings shall be determined in accordance with EN 13383-2:2013, Clause 5. shall conform to: a) Table 1 for categories CP32/90, CP45/125, CP63/180, CP90/250, CP45/180, and CP90/180 ; or b) as declared by the producer for category CPDeclared.

NOTE Guidance on the selection of RO category is given in Annex F. 5 Physical requirements 5.1 General The necessity for testing and declaring all properties in this clause is limited according to the particular application at end use or origin of the armourstone. When required, the tests specified in Clause 5 shall be carried out to determine appropriate physical properties. When the value of a property is required but not defined by specified limits the value should be declared by the producer as an XXDeclared category. For example, in Table 9 a value of a micro-Deval coefficient of less than or equal to 40 corresponds to MDE40. SIST EN 13383-1:2013
EN 13383-1:2013 (E) 13 When a property is not required, a “No requirement” category may be used. Guidance on selection of appropriate categories for specific applications may be found in national provisions in the place of use of the armourstone. NOTE 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 property being greater than or equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all less severe categories (lower values). Sampling shall be carried out as specified in EN 13383-2:2013, Clause 4. 5.2 Particle density The particle density of at least 10 pieces of armourstone (excluding fragments), shall be determined in accordance with EN 13383-2:2013, Clause 8. Using the results, the average particle density (in Mg/m3) of the pieces of armourstone tested shall be declared to 2 decimal places. Using the results, the minimum particle density (in Mg/m3) of any piece of armourstone shall be declared to 2 decimal places. 5.3 Resistance to breakage The resistance to breakage of armourstone (excluding fragments) shall be determined by testing compressive strength in accordance with EN 1926:2006, Annex A. Each specimen shall be prepared from a separate piece of armourstone. The number of specimens to be tested and the test results shall conform to the relevant requirements (or the producer's declaration for category CSDeclared) specified in Table 8 for the selected category. Table 8 — Categories of resistance to breakage requirements Mean compressive strength of 9 specimens after striking out the lowest value from 10 specimens MPa Compressive strength of no more than 2 specimens out of 10

NOTE Guidance on the selection of wear categories is given in Annex F. The test portion shall be prepared in accordance with EN 1097-1:2011, Clause 6. Where suitable aggregate from a source representative of the armourstone is not available, the test portion shall be prepared in accordance with
EN 13383-2:2013, 4.7. 5.5 Requirement associated with grouting Armourstone intended for use in a layer to be grouted with bituminous or cement mortar shall not be covered with observable clayey or other adhesive soil. 5.6 Colour Natural variation in colour supplied from a quarry (or distinct part of a quarry) with an established pattern of supply shall not be grounds for rejection of any material. The purchaser should advise the supplier of any preference for a particular general colour for the armourstone. 6 Chemical requirements 6.1 General The necessity for testing and declaring all properties in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the tests specified in Clause 6 shall be carried out to determine appropriate chemical properties. NOTE This clause generally applies to natural and manufactured armourstone. However, some recycled materials could have other chemical characteristics that do not apply to the generality of armourstone with an established pattern of use and when required, provisions valid at the place of use can be used to assess its suitability. Sampling shall be carried out as specified in EN 13383-2:2013, Clause 4. 6.2 Impurities Armourstone shall not contain any foreign matter such as scrap metal, wood and plastic in a quantity that will cause damage to the structure or the environment in which it is used (see EN 16236:2013, Table 3). 6.3 Water soluble constituents When a determination of water soluble constituents is required, an eluate shall be prepared from a representative sample of armourstone as specified in EN 1744-3. Where suitable aggregate representative of the armourstone is SIST EN 13383-1:2013
EN 13383-1:2013 (E) 15 not available, the test portion shall be obtained by crushing, using a laboratory jaw crusher, at least six separate pieces of armourstone for which the masses do not differ by more than 25 %. 7 Durability requirements 7.1 General The necessity for testing for all properties in this clause is limited according to the particular application at end use or origin of the armourstone. When required, the tests specified in Clause 7 shall be carried out to determine appropriate durability properties. When the value of a property is required but not defined by specified limits the value should be declared by the producer as an XXDeclared category. For example, in Table 13 a value of a percentage loss of mass of less than or equal to 30 corresponds to MS30. When a property is not required, a “No requirement” category may be used. Guidance on selection of approriate categories for specific applications may be found in national provisions in the place of use of the armourstone. NOTE 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 being greater than or equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all less severe categories (lower values). Sampling shall be carried out as specified in EN 13383-2:2013, Clause 4. 7.2 Constituents which affect the durability of blastfurnace and steel slags 7.2.1 Dicalcium silicate disintegration of air-cooled blastfurnace slag When required, air-cooled blast-furnace slag armourstone (excluding fr
