General Information

Overview
EN 480-6:2024 is a European standard developed by CEN that specifies a test method for identifying admixtures used in concrete, mortar, and grout through infrared (IR) analysis. This standard replaces the previous EN 480-6:2005 version and introduces updated testing procedures including the use of the Attenuated Total Reflectance (ATR) technique. EN 480-6:2024 forms part of the comprehensive EN 480 series dedicated to the testing of concrete admixtures, ensuring consistent and reliable quality control in construction materials.
Key Topics
Scope and Purpose
- Defines a standardized infrared spectrophotometric method to identify chemical admixtures used in concrete, mortar, and grout.
- Applicable for dry material samples, typically dried at 105 ± 3 °C to prepare for testing.
Testing Procedure
- Dry preparation of admixture samples in accordance with EN 480-8 for determining conventional dry material content.
- Use of an infrared spectrometer with accessories like NaCl windows, ATR modules, or KBr pellets for sample analysis.
- Recording IR spectra between 4000 cm⁻¹ and 600 cm⁻¹ (optionally up to 250 cm⁻¹) to capture characteristic absorption peaks.
Equipment
- Infrared spectrometer capable of transmission or absorption mode.
- Oven with forced ventilation for sample drying.
- Balance with high precision for weighing samples.
- Sample preparation tools including evaporating dishes, presses, and desiccators.
Results Interpretation
- Evaluation based on the similarity of spectral characteristic peaks compared with reference or initial type-testing samples.
- Requires skilled personnel experienced in infrared spectrophotometry for accurate conformity assessment.
Test Reporting
- Includes detailed information such as test date, laboratory identification, sample origin, drying and preparation methods, type of equipment used, and recorded spectra.
Applications
EN 480-6:2024 is essential for laboratories, manufacturers, and quality control entities involved in the production and certification of admixtures for:
Concrete Admixtures
- Identification of additives promoting properties such as setting time control, workability, and durability enhancement.
Mortar and Grout Additives
- Precise characterization of chemical agents to ensure consistent performance in masonry and repair materials.
Quality Assurance
- Reliable identification method to validate batch consistency and detect deviations or adulterations in admixture formulations.
Research and Development
- Support for the development of new admixture products through detailed molecular characterization using IR spectra.
Related Standards
EN 480-6:2024 should be applied in conjunction with other parts of the EN 480 series, including but not limited to:
- EN 480-1: Reference concrete and mortar for testing.
- EN 480-8: Determination of conventional dry material content (directly referenced for sample preparation).
- EN 480-2: Determination of setting time of admixtures.
- EN 480-4: Bleeding of concrete assessment.
- EN 480-5: Capillary absorption measurement.
- EN 480-10: Water-soluble chloride content determination.
- EN 480-12: Alkali content determination in admixtures.
These interconnected standards ensure holistic testing and evaluation procedures for admixtures enhancing the reliability and safety of cementitious materials used globally.
