FprEN 12620

Aggregates for concrete

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 concrete.
It covers aggregates having an oven dried particle density greater than 2,00 Mg/m3. It also covers recycled and manufactured aggregates 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 and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constituents of recycled aggregates.

Gesteinskörnungen für 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.
