Overview

EN 15191:2024 - published by CEN - defines a harmonised system for the classification of glassfibre reinforced concrete (GRC) used in precast concrete products. The standard supports the design process by specifying material classes, key mechanical parameters and application-specific considerations. It applies only when factory production control follows EN 1169 and does not provide design methods.

Key points from the standard:

• Classification is based on characteristic bending stresses at the limit of proportionality (LOP) and at the modulus of rupture (MOR). Tests are performed in accordance with EN 1170.
• Characteristic values correspond to the 5 % fractile with a 75 % confidence level, using specimens at 28 days.
• Glassfibre properties and retention requirements are covered by EN 15422 and EN 14649 (SIC test).

Key Topics

• Material parameters: The two primary characteristic values are

  • σ_LOP: bending stress at limit of proportionality
  • σ_MOR: bending stress at modulus of rupture

• Acceptance criteria: The standard requires that

  • σ_MOR ≥ 1.2 × σ_LOP
  • ε_MOR ≥ 1.2 × ε_LOP

• Material classes and examples: Typical denomination uses the pair (σ_LOP/σ_MOR), for example:

  • GRC 6/8, GRC 7/10, GRC 7/12, GRC 7/14, GRC 7/16, GRC 7/18

• Statistical evaluation: Characteristic values are derived from producer test data using the formula f_c = x̄ - k·s with k values given (referenced from ISO 12491).

• Application factor L: For long-term exposure to natural weathering, an application-specific factor L is used to account for strength retention. Where long-term data are not available, EN 15191 provides default minimum L values (for example, 0.75 for class 6/8, 0.7 for 7/10 and 7/12, and 0.6 for higher MOR classes).

• Oriented fibres: Processes producing oriented fibre arrangements are acknowledged; classification must reflect fibre direction and specimen orientation during testing.

Applications

EN 15191:2024 is essential for stakeholders involved in:

• Precast component manufacturers using GRC
• Quality managers establishing factory production control (FPC) per EN 1169
• Specifiers and designers who require consistent material performance data (material selection, verification and acceptance testing)

The classification facilitates reliable specification of GRC material performance for façade panels, architectural elements and other precast applications where GRC is used.

Related Standards

• EN 1169 - factory production control requirements for GRC
• EN 1170 - test methods for GRC (mechanical testing and cyclic ageing)
• EN 14649 - SIC test for strength retention of glass fibres in cement/concrete
• EN 15422 - specification of glassfibres for mortar and concrete
• EN 206 and ISO 12491 - referenced for related materials and statistical methods

For implementation, consult the full EN 15191:2024 text and coordinate testing and FPC with the appropriate national standards body.
