Classification for discrete polymer fibre for fibre-reinforced cementitious composites
This document specifies discrete polymer fibres with a nominal length of 80 mm or less mixed in concrete and mortar. The quality and performance specified in this standard are the raw material resin of discrete polymer fibres, nominal fibre diameter and its allowable range, nominal fibre length and its allowable range, fibre cross-sectional shape, fibre longitudinal shape, grade of fibre strength, and grade of fibre elasticity. There are a wide variety of discrete polymer fibres used to reinforce cement composites. Currently, in discrete polymer fibres products distributed as industrial products, there are many types of raw material resins and various shapes. In addition, the applications that have been used in practical fields are so wide, from structural applications that require high mechanical reinforcement performance to crack control and peeling prevention that are easier to use. Therefore, to select an appropriate product from a wide variety of discrete polymer fibres, the characteristics of discrete polymer fibres need to be classified and revealed based on a unified evaluation method. This document allows manufacturers to ensure the performance of discrete polymer fibres are in accordance with an adequate standard in response to various user requests.

Overview
ISO 13182:2026 - Classification for Discrete Polymer Fibre for Fibre-Reinforced Cementitious Composites sets a unified classification system for discrete polymer fibres used in concrete and mortar. This international standard enables the specification and selection of fibres by defining key characteristics and performance metrics, promoting consistency and quality for construction materials worldwide. The guideline is essential for manufacturers, designers, and purchasers seeking reliable, well-classified polymer fibres for fibre-reinforced cementitious composites (FRCCs).
Key Topics
ISO 13182:2026 addresses the following critical aspects of discrete polymer fibres:
- Material Specification: Fibre classification by raw material resin, including aramid, polyamide (nylon), polyethylene, polypropylene, polyvinyl alcohol, and polyoxymethylene.
- Dimensional Properties: Nominal fibre diameter and length, with allowable tolerances for both diameter and length.
- Shape Characteristics: Definition and notation for fibre cross-sectional shapes (e.g., circular, oval, rectangular) and longitudinal shapes (e.g., straight, waved, embossed, split).
- Mechanical Performance: Classification of fibres by grade of tensile strength and modulus of elasticity, providing clear categories to match engineering needs.
- Quality Control: Tolerance grades for key dimensions and mechanical properties to ensure performance consistency.
- Notation System: Standard notation for fibre parameters, simplifying product specification and selection.
- Test Methods Reference: Guidance on test methods in line with ISO 23523 for measuring fibre properties.
Applications
The classification framework in ISO 13182:2026 is vital for a range of practical uses, including:
- Structural Reinforcement: Selection of high-performance polymer fibres for structural concrete and mortar, improving tensile strength and durability.
- Crack Control: Choosing suitable fibres for controlling shrinkage cracks in slabs, pavements, and precast products.
- Peeling and Spalling Prevention: Applying appropriate fibres to reduce surface peeling and improve the longevity of cementitious composites.
- Flexible Product Development: Enabling manufacturers to tailor fibre products to specific applications and user requirements.
- Project Specification: Facilitating clear, standardized communication between suppliers, contractors, and designers, ensuring intended performance is achieved.
- Quality Assurance: Providing benchmarks for raw material and product testing, supporting compliance and certification processes.
Related Standards
Several other international standards support the implementation and testing of discrete polymer fibres for FRCCs:
- ISO 23523: Test methods for discrete polymer fibre for fibre-reinforced cementitious composites. Establishes procedures for measuring fibre diameter, length, tensile strength, and initial modulus of elasticity.
- ISO/TC 71/SC 6: Series related to non-traditional reinforcing materials for concrete structures.
- ISO/IEC Directives: Editorial rules for drafting and maintaining international standards.
Practical Value
ISO 13182:2026 enhances the reliability, safety, and performance of fibre-reinforced concrete by creating a consistent language for fibre classification and selection. The standard is a key resource empowering manufacturers to meet global market demands, ensuring buyers and end-users receive clearly specified, fit-for-purpose polymer fibres for a wide array of cementitious composite applications. Consistent classification and testing reduce project risk while supporting innovative design and robust quality control in infrastructure and building projects.
