Introduction




Concrete is one of the most widely used materials in construction, due to its versatility, durability, strength, and sustainability. However, concrete structures also require careful planning, design, execution, inspection, testing, and maintenance to ensure their safety, performance, and quality. That's why it is essential to follow a recognized standard that covers all aspects of concrete construction.


NF EN 13670 is such a standard. It is a French national standard that specifies the execution of concrete structures for building and civil engineering works. It applies to both on-site works and prefabricated concrete elements. It is based on BS EN 13670:2009, which is a European standard that harmonizes the execution of concrete structures across Europe.


NF EN 13670 provides a clear and flexible specification that can be adapted to different types of concrete structures, such as foundations, columns, beams, slabs, walls, stairs, bridges, tunnels, dams, etc. It also provides guidance on how to achieve the desired quality level of concrete structures according to their exposure classes, design life span, loading conditions, environmental factors, etc.


By following NF EN 13670, you can ensure that your concrete structures meet the requirements of Eurocodes (the European standards for structural design), as well as other relevant regulations and codes of practice. You can also benefit from improved efficiency, productivity, cost-effectiveness, sustainability, innovation, and competitiveness in your concrete construction projects.


But how can you access NF EN 13670? Well, you can purchase a hard copy or a digital copy from the official publisher, Association Francaise de Normalisation (AFNOR). However, if you want to save some money and time, you can also download NF EN 13670 PDF for free from some online sources. We will show you how to do that in the later sections of this article.


NF EN 13670: Execution of concrete structures




Before we show you how to download NF EN 13670 PDF for free, let's take a closer look at what this standard contains and what it covers. NF EN 13670 consists of four main sections:



  • Section 1: General



  • Section 2: Materials



  • Section 3: Execution



  • Section 4: Conformity evaluation and compliance criteria



Each section contains several clauses that provide detailed specifications and recommendations on various aspects of concrete construction. Here are some of the topics that are covered by NF EN 13670:



  • The scope and objectives of the standard



  • The definitions and terms used in the standard



  • The roles and responsibilities of the parties involved in the execution of concrete structures, such as the client, the designer, the contractor, the supervisor, the testing laboratory, etc.



  • The quality management system and documentation required for the execution of concrete structures



  • The selection and specification of materials for concrete structures, such as cement, aggregates, water, admixtures, reinforcement, prestressing tendons, embedded items, etc.



  • The production and delivery of concrete, including batching, mixing, transporting, placing, compacting, curing, etc.



  • The fabrication and installation of prefabricated concrete elements, including handling, storage, erection, connection, grouting, etc.



  • The execution of formwork and falsework for concrete structures, including design, materials, erection, removal, etc.



  • The execution of reinforcement and prestressing for concrete structures, including design, materials, fabrication, installation, tensioning, grouting, etc.



  • The execution of joints and bearings for concrete structures, including design, materials, installation, sealing, etc.



  • The execution of surface finishes and coatings for concrete structures, including design, materials, preparation, application, curing, etc.



  • The inspection and testing of concrete structures during and after execution, including sampling, testing methods, acceptance criteria, non-conformities, corrective actions, etc.



  • The maintenance and repair of concrete structures after execution, including design, materials, methods, inspection, testing, etc.



NF EN 13670 also provides several informative annexes that give additional guidance and examples on some topics covered by the standard. For instance:



  • Annex A gives examples of exposure classes for concrete structures according to their environmental conditions



  • Annex B gives examples of quality levels for concrete structures according to their design life span and loading conditions



  • Annex C gives examples of conformity evaluation methods for concrete structures according to their quality levels



  • Annex D gives examples of documentation required for the execution of concrete structures according to their quality levels



  • Annex E gives examples of inspection and testing plans for concrete structures according to their quality levels



NF EN 13670 is fully compatible with BS EN 13670:2009. In fact, NF EN 13670 is identical to BS EN 13670:2009 except for some editorial changes. Therefore, if you are familiar with BS EN 13670:2009, you can easily use NF EN 13670 as well.


NF EN 13670/CN: National annex to NF EN 13670




NF EN 13670 is a national standard that applies to France. However, it also allows for some national adaptations and specificities that are not covered by BS EN 13670:2009. These adaptations and specificities are provided in a separate document called NF EN 13670/CN, which is the national annex to NF EN 13670.


NF EN 13670/CN contains several clauses that modify or supplement some clauses of NF EN 13670. For instance:



  • Clause CN.1 modifies clause 4.1.3.1 of NF EN 13670 regarding the minimum cement content for different exposure classes



  • Clause CN.2 modifies clause 4.1.3.2 of NF EN 13670 regarding the maximum water/cement ratio for different exposure classes



of NF EN 13670 regarding the minimum air content for different exposure classes


  • Clause CN.4 modifies clause 4.1.3.4 of NF EN 13670 regarding the minimum strength class for different exposure classes



  • Clause CN.5 modifies clause 4.2.2.1 of NF EN 13670 regarding the minimum cover for reinforcement and prestressing tendons



  • Clause CN.6 modifies clause 4.2.2.2 of NF EN 13670 regarding the tolerances for cover



  • Clause CN.7 modifies clause 4.2.3 of NF EN 13670 regarding the requirements for reinforcement and prestressing tendons



  • Clause CN.8 modifies clause 4.3.1 of NF EN 13670 regarding the requirements for formwork and falsework



  • Clause CN.9 modifies clause 4.3.2 of NF EN 13670 regarding the requirements for joints and bearings



  • Clause CN.10 modifies clause 4.3.3 of NF EN 13670 regarding the requirements for surface finishes and coatings



  • Clause CN.11 modifies clause 5.1 of NF EN 13670 regarding the conformity evaluation methods and criteria



  • Clause CN.12 modifies clause 5.2 of NF EN 13670 regarding the inspection and testing plans



  • Clause CN.13 modifies clause 5.3 of NF EN 13670 regarding the acceptance criteria for concrete strength



  • Clause CN.14 modifies clause 5.4 of NF EN 13670 regarding the non-conformities and corrective actions



NF EN 13670/CN also provides several informative annexes that give additional guidance and examples on some topics covered by the national annex. For instance:



  • Annex ZA gives examples of national regulations and codes of practice that are relevant to the execution of concrete structures in France



  • Annex ZB gives examples of national standards and specifications that are relevant to the execution of concrete structures in France



  • Annex ZC gives examples of national technical approvals and certifications that are relevant to the execution of concrete structures in France



NF EN 13670/CN is intended to be used in conjunction with NF EN 13670. It does not replace or contradict any clauses of NF EN 13670, but rather complements or clarifies them according to the French context and practice.
