Overview
EN 13263-1:2005+A1:2009 (CEN) defines silica fume for concrete - the amorphous silicon dioxide by-product collected from smelting silicon metal and ferro‑silicon alloys. This Part 1 standard specifies definitions, chemical and physical requirements, packaging/marking rules and conformity criteria for silica fume intended as a Type II addition in concrete, mortars, grouts and other mixes. It does not prescribe rules for how to use silica fume in concrete (see EN 206‑1 for use and performance requirements).
Key Topics
- Scope and definitions: undensified, densified and slurry forms; terminology such as activity index, autocontrol, certified silica fume.
- Chemical requirements:
- SiO2 content: characteristic classes (Class 1 ≥ 85% SiO2; Class 2 ≥ 80% SiO2) as determined per EN 196‑2.
- Elemental Si ≤ 0.4% (ISO 9286).
- Free CaO ≤ 1.0% (EN 451‑1).
- Sulfate (SO3) ≤ 2.0% (EN 196‑2); alkalis content to be declared.
- Physical requirements: properties such as bulk density (densified > ~500 kg/m3; undensified ≈150–350 kg/m3), fineness and specific surface area (BET/ISO 9277); activity index to assess pozzolanic contribution.
- Conformity and quality control:
- Factory production control and autocontrol testing by the manufacturer.
- Statistical sampling plans, acceptance criteria and procedures for certification.
- Reference to EN 13263‑2 for conformity evaluation and to Annex A for release of dangerous substances / radioactivity.

La pertinence de la norme EN 13263-1 se manifeste également à travers sa capacité à intégrer des ajouts de fumées de silice provenant d’alliages de calcium-silicium ainsi que d'autres types de fumées de silice, conformément aux exigences locales. Cela montre une flexibilité appréciable, permettant aux fabricants de s'adapter aux spécificités locales et à la diversité des matières premières disponibles. En résumé, la norme EN 13263-1:2005+A1:2009 est une ressource indispensable pour les professionnels du béton, assurant que l’utilisation des fumées de silice se fait selon des standards élevés, favorisant ainsi l'innovation tout en garantissant la qualité des constructions.
The EN 13263-1:2005+A1:2009 standard, titled "Silica fume for concrete - Part 1: Definitions, requirements and conformity criteria," serves a crucial role in defining the parameters for silica fume utilized in concrete applications. The scope of this European Standard is comprehensive, focusing on silica fume, a by-product of the smelting process for producing silicon metal and ferro-silicon alloys. Its classification as a type II addition in concrete, as per EN 206-1, highlights its significance in enhancing concrete properties when used appropriately. One of the primary strengths of this standard is its detailed requirements for the chemical and physical properties of silica fume, ensuring that only materials meeting stringent quality criteria are used in construction. This standardization is essential not only for maintaining the integrity of construction projects but also for ensuring consistency in the performance of silica fume across various applications such as concrete, mortars, and grouts. Moreover, EN 13263-1 establishes clear conformity criteria and related rules that guide manufacturers and users in assessing compliance, thereby bolstering confidence in the material's performance. However, it is important to note that this standard does not provide rules for the actual use of silica fume in concrete; instead, it defers to EN 206-1 for those specifics. This delineation allows for a more robust approach where EN 206-1 can accommodate national acceptance conditions and supplementary rules regarding the incorporation of various types of silica fumes. The standard's relevance cannot be overstated, especially in the context of sustainable construction practices. By promoting the use of silica fume, it facilitates the production of high-performance concrete with enhanced durability and strength characteristics, which can lead to longer-lasting structures and reduced maintenance costs. In summary, EN 13263-1:2005+A1:2009 is a pivotal document that solidifies the foundation for the use of silica fume in concrete, characterized by its rigorous requirements, clear conformity criteria, and alignment with broader construction standards. Its establishment of parameters for silica fume is essential for quality assurance in concrete production, making this standard a valuable resource for engineers, manufacturers, and builders alike.

SIST EN 13263-1의 주요 강점 중 하나는 실리카 연무가 콘크리트, 모르타르, 그라우트 및 기타 혼합물에서 사용할 수 있도록 요구되는 화학적 및 물리적 특성에 대한 명확한 기준을 제공한다는 것입니다. 이는 다양한 건설 공정에서 실리카 연무를 적절히 활용할 수 있게 하며, 기술적 신뢰성을 높입니다. 또한, 적합성 기준과 관련 규칙을 명시하여, 품질 관리 및 표준 준수를 보장할 수 있습니다. 이 표준은 실리카 연무 사용에 대한 구체적인 규칙을 제공하지 않지만, EN 206-1에서 제시된 조건과 보완적인 국가 표준에 따라 실리카 연무를 사용하는 방법에 대한 지침을 제공받을 수 있습니다. 이를 통해 사용자는 지역적 요구사항을 반영한 실용적인 기준을 적용할 수 있게 됩니다. SIST EN 13263-1:2005+A1:2009은 건설 산업에서 실리카 연무의 중요성을 강조하고, 그 사용에 관한 명확한 기준을 제시하여, 품질 높은 콘크리트 구조물의 기초를 확립할 수 있도록 돕습니다. 실리카 연무의 효과적 사용은 건축물의 내구성을 향상시키며, 지속 가능한 건설에 기여하는 점에서도 중요한 의미를 갖고 있습니다.
