It covers mineral-origin LWAs with particle densities ≤ 2000 kg/m³ or loose bulk densities ≤ 1200 kg/m³, including natural, manufactured, recycled and industrial by‑product LWAs. The standard (approved March 2016) supersedes earlier parts EN 13055-1 and EN 13055-2 and applies to LWA for concrete, mortar and grout, bituminous mixtures, surface treatments, and unbound or hydraulically bound applications.
Key topics and technical requirements
EN 13055:2016 specifies product characteristics, test methods and factory production control (FPC). Major technical topics include:
- Density: particle density and loose bulk density limits and definitions.
- Grading and particle size: undersize/oversize limits, grading requirements for aggregates and fillers.
- Water characteristics: water content, water absorption and water suction height.
- Mechanical properties: bulk crushing resistance, resistance to disintegration, compressibility, confined compressive strength, resistance to cyclic compressive loading, fragmentation and wear.
- Durability: freeze–thaw resistance, thermal shock resistance, polishing and abrasion resistance.
- Chemical properties: water-soluble constituents, chlorides, sulphur compounds, loss on ignition, organic contaminants and alkali-silica reactivity for natural LWA.
- Thermal: thermal conductivity and moisture correction.
- Safety & compliance: dangerous substances assessment, marking, labelling and designation.
- Testing & conformity: sampling, specimen preparation, test frequencies, AVCP (assessment and verification of constancy of performance) and FPC requirements.
Annexes provide normative lists of source materials (Annex A), related product standards (Annex B) and specific test guidance (Annex C–F).

Die Norm EN 13055:2016 behandelt die Eigenschaften von Leichtaggregaten (LWA) und deren daraus abgeleiteten Füllstoffen, die durch die Verarbeitung natürlicher oder hergestellter Materialien gewonnen werden. Sie ist besonders relevant für die Verwendung in Beton, Mörtel, Gießmassen, bituminösen Mischungen und Oberflächenbehandlungen sowie für ungebundene und hydraulisch gebundene Anwendungen im Bauwesen. Ein herausragendes Merkmal der Norm ist die klare Definition des Geltungsbereichs, einschließlich der spezifischen Typen von LWA, die behandelt werden. Dazu gehören natürliche LWA, solche, die aus natürlichen Materialien hergestellt werden, sowie LWA, die aus Industrieabfallprodukten oder recycelten Ausgangsmaterialien gewonnen werden. Dies bietet eine umfassende Grundlage für die Nutzung von Leichtaggregaten im Bauwesen und unterstützt die nachhaltige Verwendung von Materialien, was in der heutigen Bauindustrie von hoher Bedeutung ist. Ein weiterer Vorteil der EN 13055:2016 ist, dass sie Anforderungen spezifiziert, die je nach Anwendungsfall angepasst werden können. Dies ermöglicht eine Flexibilität in der Anwendung der Norm, sodass unterschiedliche LWA-Typen und deren spezifische Einsatzmöglichkeiten angemessen berücksichtigt werden können. Die Norm bietet somit nicht nur große Relevanz für die Verwendung von Leichtaggregaten, sondern auch für die Anpassungsfähigkeit an verschiedene Baubedürfnisse und -standards.

Dies gewährleistet, dass Anwender einen klaren Überblick über die akzeptablen Materialien erhalten, welche die Qualität und die Eigenschaften der verwendeten LWA beeinflussen können. Insgesamt sticht die Norm EN 13055:2016 als wichtiger Leitfaden für die Verwendung von Leichtaggregaten im Bauwesen hervor, da sie nicht nur detaillierte Anforderungen und Merkmale definiert, sondern auch auf die Bedeutung von Nachhaltigkeit und Ressourcenschonung hinweist.
The EN 13055:2016 standard provides a comprehensive framework for the properties and application of Lightweight Aggregates (LWA), which are crucial for various construction works. The scope of this standard is notably robust, encompassing lightweight aggregates derived from both natural and manufactured sources. Specifically, it details the properties of LWAs with particle densities not exceeding 2000 kg/m3 and loose bulk densities of up to 1200 kg/m3, ensuring that practitioners are well-guided in their selection and utilization of these materials. One of the key strengths of EN 13055:2016 is its inclusivity. The standard addresses a wide range of LWAs, including natural sources, those manufactured from natural materials, by-products from industrial processes, and recycled sources. This approach not only promotes sustainable practices within the industry but also allows for the utilization of innovative recycled materials, fostering a circular economy. Moreover, the standard provides clear annotations regarding different applications, enabling users to refer to Annex A for a specific list of materials that meet the outlined properties. This feature is particularly beneficial for engineers and architects who require precise specifications in their projects. Additionally, it conveniently references other related standards, such as EN 12620 and EN 13043, indicating a seamless integration of knowledge across different material guidelines. The adaptive nature of the requirements is another significant advantage, as they may be tailored to suit particular applications. This flexibility allows for a customized approach based on varying project needs, thus enhancing the standard's relevance across diverse construction scenarios. In summary, EN 13055:2016 is an essential standard that effectively outlines the parameters for Lightweight Aggregates, balancing specificity with flexibility and promoting the sustainable use of materials in construction practices. Its thoroughness and applicability make it a critical reference for professionals in the field.
La norme EN 13055:2016 définit les propriétés des granulats légers (LWA) et des fillers dérivés, obtenus par le traitement de matériaux naturels ou manufacturés, ainsi que des mélanges de ces granulats pour des applications dans le béton, le mortier, et les traitements de surface. Le champ d'application de cette norme est essentiel pour les professionnels du secteur de la construction, car il encadre les granulats légers d'origine minérale ayant des densités de particules ne dépassant pas 2000 kg/m3. Un des points forts de la norme EN 13055:2016 est son approche claire et structurée concernant les différents types de LWA. Elle couvre non seulement les granulats naturels, mais aussi ceux fabriqués à partir de matériaux naturels, de sous-produits de processus industriels ou de matériaux recyclés. Ce champ d'application inclusif est particulièrement pertinent dans le contexte actuel où la durabilité et le recyclage jouent un rôle crucial dans la construction moderne. La norme fournit également une liste exhaustive de matériaux source dans l'Annexe A, ce qui facilite l'identification des granulats conformes. Les exigences spécifiques pour différents types d'applications, mentionnées dans la norme, permettent d'assurer que les LWA peuvent être utilisés dans une variété d'applications de construction, allant du béton au mélange bitumineux, tout en respectant des exigences de performance adaptées. La pertinence de cette norme est renforcée par le fait qu'elle prend en compte les évolutions du marché et les standards en matière de durabilité. Bien que certaines exigences puissent ne pas être également applicables à tous les types de LWA, le fait que des adaptations soient possibles en fonction de l'utilisation finale illustre la flexibilité et l'adaptabilité des normes aux besoins spécifiques des projets de construction. En somme, la norme EN 13055:2016 représente un cadre crucial pour la sélection, l'utilisation et l'évaluation des granulats légers dans le secteur de la construction.
