Comprehensive Guide to BS EN 934-2 Concrete Admixtures Laboratory Testing Service Provided by Eurolab

BS EN 934-2 is a European standard that governs the laboratory testing of concrete admixtures, specifically those used in the production of fresh and hardened concrete. This standard is part of a larger family of standards, including ISO 11467, ASTM C 494/C 494M, and TSE 701.

Legal and Regulatory Framework

The European Unions Construction Products Regulation (CPR) requires that all construction products, including concrete admixtures, undergo testing and certification to ensure compliance with EU regulations. BS EN 934-2 is a key standard in this process, providing a framework for the evaluation of concrete admixture performance.

International and National Standards

The following international and national standards are relevant to BS EN 934-2:

  • ISO 11467:2010(E) - Methods of test for hydraulic cement paste

  • ASTM C 494/C 494M-18 - Specification for Chemical Admixtures for Concrete

  • TSE 701 - Turkish Standard for Concrete Admixtures

  • BS EN 12350-1:2009A1:2016 - Testing fresh concrete - Part 1: Sampling, testing and evaluating in-situ concrete

    • Standard Development Organizations

    The standard development process involves collaboration between various organizations, including:

  • CEN (European Committee for Standardization)

  • ISO (International Organization for Standardization)

  • ASTM International

  • TSE (Turkish Standards Institution)

    • These organizations work together to develop and maintain standards that ensure consistency and comparability across different regions and industries.

    Evolution of Standards

    Standards evolve over time as new technologies, materials, and testing methods emerge. BS EN 934-2 is updated periodically to reflect these changes and ensure that the standard remains relevant and effective.

    Standard Numbers and Scope

    The following are some key standard numbers and their scope:

  • BS EN 934-2:2019 - Concrete admixtures - Part 2: Mechanical and physical tests

  • ISO 11467:2010(E) - Methods of test for hydraulic cement paste

  • ASTM C 494/C 494M-18 - Specification for Chemical Admixtures for Concrete

  • Maintain a controlled temperature and humidity environment (e.g., 23C 2C and 50 RH 10)

    • 4. Sample Preparation Procedures

  • Weigh and mix samples according to standard procedures

    • 5. Testing Parameters and Conditions

  • Measure mechanical and physical properties, such as slump flow, flow time, or air content

    • 6. Measurement and Analysis Methods

  • Use specialized software and instruments to analyze test results

    • The following are the key aspects of test reporting and documentation:

    1. Reporting Requirements

  • Provide detailed reports on test results, including any deviations from standard procedures

    • 2. Documentation Requirements

  • Maintain records of all testing activities, including sample preparation, testing, and analysis

    • 3. Certification and Accreditation

  • Ensure that testing facilities are accredited to relevant standards (e.g., ISO/IEC 17025)
