Determination of shear strength between different layers of multilayer components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure
This European Standard specifies a method of determining the shear strength under short-term loading between the different layers of prefabricated multilayer components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to prEN 1520. This test method is suitable only for evaluation of conformity purposes during production of multilayer components.
Bestimmung der Scherfestigkeit zwischen den verschiedenen Schichten mehrschichtiger Bauteile aus dampfgehärtetem Porenbeton oder haufwerksporigem Leichtbeton
Diese Europäische Norm legt ein Verfahren fest zur Bestimmung der Scherfestigkeit bei kurzzeitiger Belastung zwischen den verschiedenen Schichten mehrschichtiger Bauteile aus dampfgehärtetem Porenbeton (AAC) nach prEN 12602 oder haufwerksporigem Leichtbeton (LAC) nach prEN 1520. Dieses Prüfverfahren ist nur zum Zwecke der Konformitätsbewertung bei der Herstellung mehrschichtiger Bauteile geeignet.
Détermination de la résistance au cisaillement entre les différentes couches d'éléments multicouches réalisés en béton cellulaire autoclavé ou en béton de granulats légers à structure ouverte
La présente norme européenne définit une méthode pour déterminer la résistance au cisaillement sous charges de courte durée entre les différentes couches des éléments préfabriqués multicouches réalisés en béton cellulaire autoclavé (AAC) conforme au prEN 12602 ou en béton à granulats légers à structure ouverte (LAC) conforme à l'EN 1520. Cette méthode d'essai n'est appropriée qu'à l'évaluation de la conformité au cours de la production des éléments multicouches.

Overview
EN 1742:1998 defines a standardized testing method for determining the shear strength between different layers in multilayer components made from autoclaved aerated concrete (AAC) or lightweight aggregate concrete with open structure (LAC). Issued by CEN, this European Standard ensures the consistent assessment of interlayer shear strength under short-term loading, primarily serving the evaluation of conformity during the production of prefabricated multilayer concrete components.
This standard is an integral part of quality control for manufacturers producing multilayer concrete elements according to prEN 12602 (AAC) and prEN 1520 (LAC), ensuring structural reliability and performance.
Key Topics
- Shear strength testing: Provides a robust method for assessing the bond and mechanical integrity between distinct concrete layers within a multilayer component.
- Material coverage: Applies to multilayer products composed of either autoclaved aerated concrete (AAC) or lightweight aggregate concrete (LAC) featuring an open structure.
- Short-term loading: Specifies testing under conditions relevant to initial mechanical performance, focusing on short-term, rather than long-term, load situations.
- Conformity assessment: Outlines procedures for quality assurance and verification of products during manufacturing to confirm compliance with production standards.
Applications
EN 1742:1998 plays a critical role in several applications across the construction and precast concrete industries:
- Quality control in production: Used by manufacturers to ensure every batch of multilayer components meets the required shear strength, thus supporting consistent product quality.
- Prefabricated building components: Essential for producers of wall panels, floor slabs, and other composite structural elements where layers of AAC or LAC are bonded together.
- Structural reliability: By verifying the shear strength between layers, the standard helps prevent product failures and assures safe usage in building environments.
- Specification in procurement: Architects, engineers, and contractors can reference EN 1742:1998 to specify shear strength requirements when procuring multilayer AAC or LAC components, leading to enhanced project reliability.
Related Standards
For broader compliance and integration, EN 1742:1998 connects with the following standards within the concrete and construction sector:
- prEN 12602: Covers requirements and performance for autoclaved aerated concrete products, including multilayer components.
- prEN 1520: Details specifications and performance criteria for lightweight aggregate concrete with open structure, relevant for LAC multilayer elements.
- EN 206: Specifies requirements for the production and conformity of concrete in building and civil engineering works.
- EN 1992 (Eurocode 2): Provides design rules for concrete structures, where validated shear performance is vital for safety.
By utilizing EN 1742:1998, manufacturers and construction professionals can guarantee that multilayer AAC and LAC components deliver reliable shear strength, maintain structural soundness, and comply with European construction product standards. The adoption of this standard enhances quality assurance, structural performance, and customer confidence in multilayer concrete products.
