SIST EN 197-5:2021 - Cement - Part 5: Portland-composite cement CEM II/C-M and Composite cement CEM VI

Overview

EN 197-5:2021 (CEN) specifies requirements for two cement types not covered by EN 197-1: Portland‑composite cement CEM II/C‑M and Composite cement CEM VI. Its scope covers cements intended for the preparation of concrete, mortar, grout and similar products while excluding common cements (EN 197-1), very low heat special cements (EN 14216), supersulfated cements (EN 15743), calcium aluminate cements (EN 14647) and masonry cements (EN 413-1). The standard supports sustainability objectives by enabling lower clinker content through defined combinations of supplementary cementitious materials (SCMs) and limestone.

Key topics and technical requirements

  • Composition and constituents: Defines permitted mixes of clinker, SCMs (granulated blast‑furnace slag, fly ash, pozzolana, calcined clays, silica fume) and limestone. Typical composition ranges cover lower clinker content (about 35–64% depending on cement type) with SCMs and limestone making up the balance (SCM proportions up to ~59% and limestone up to 20% where applicable).
  • Strength classes and early strength: Uses the familiar EN strength classes (32,5 / 42,5 / 52,5) with early strength designations L, N, R and optional low‑heat notation LH.
  • Chemical limits: Limits on sulfate (SO3) and chloride contents apply; sulfate can be up to around 4.5% in certain compositions and chloride is normally limited to ≤ 0.10% by mass unless otherwise declared for specific CEM VI formulations.
  • Testing & conformity: References EN 196‑2 for chemical analysis and EN 197‑2:2020 for assessment and verification of constancy of performance (factory production control, initial inspection, continuing surveillance, audit testing).
  • Designation, marking & labelling: Specifies how to designate product type (e.g., “CEM II/C‑M (S‑V) 42,5 N – LH”), and what information must appear on packaging or delivery documents (standard designation, manufacturer/plant, weight, certification body).

Practical applications

  • Use in structural and non-structural concrete, mortars and grouts where reduced clinker content or specific SCM combinations are desired.
  • Supports sustainable construction by enabling cement formulations with lower embodied CO2 through higher SCM/limestone content.
  • Informs material selection for engineers, specifiers and contractors needing compliance with European cement standards and project durability requirements.

Who uses this standard

  • Cement manufacturers and formulators developing CEM II/C‑M and CEM VI products
  • Construction materials laboratories and test houses
  • Specifiers, structural engineers and architects selecting cements for concrete and mortar
  • Certification bodies and regulatory authorities performing conformity assessment

Related standards

  • EN 197-1:2011 (common cements)
  • EN 197-2:2020 (conformity assessment)
  • EN 196-2 (chemical testing) and standards listed in exclusions (EN 14216, EN 15743, EN 14647, EN 413-1)

Keywords: EN 197-5:2021, Portland‑composite cement, CEM II/C‑M, Composite cement CEM VI, cement standard, concrete, mortar, compliance, clinker reduction, supplementary cementitious materials.

SIST EN 197-5:2021は、ポートランド複合セメントCEM II/C-Mおよび複合セメントCEM VIに関する標準であり、主にコンクリート、モルタル、グラウトの準備に使用されます。この標準は、EN 197-1ではカバーされていないポートランド複合セメントCEM II/C-Mと、異なるタイプの複合セメントCEM VIを対象としており、セメント業界における重要な規範となっています。 この標準の強みは、特定の用途に応じたセメントの特性を明確に定義している点です。特に、ポートランド複合セメントCEM II/C-Mは、従来のポートランドセメントに複合材料を加えることで、より高い強度や耐久性を実現しており、これにより環境負荷を軽減しつつ、高性能な構造材としての利点を提供します。また、CEM VIは、特異な使用目的に適した複合セメントであり、その柔軟性と適応性は、建設プロジェクトにおける多様なニーズに応えるものとなっています。 SIST EN 197-5:2021は、確認された性能を提供するための基準を設定し、セメントの製造と使用において一貫性を持たせることを目的としています。この標準は、コンクリート関連の技術者、施工業者、設計者にとって、品質管理や材料選定において重要なリソースとなるでしょう。さらに、標準は、他の関連するセメントの種類（EN 197-1、EN 14216、EN 15743、EN 14647、EN 413-1など）との明確な区別を設けることで、特定の用途に対する理解を深め、誤用を避ける手助けをしています。 標準の関連性は、現代の建設業界において持続可能性がますます求められる中で、高性能かつ環境に優しいセメントの重要性を強調する点にあります。新しい材料技術が進化する中で、SIST EN 197-5:2021は、業界の進展と持続可能な建設方法の採用に寄与するものとして、高く評価されるべきです。

SIST EN 197-5:2021 문서는 포틀랜드 복합 시멘트 CEM II/C-M 및 복합 시멘트 CEM VI에 관한 표준으로, EN 197-1에서 다루지 않는 새로운 유형의 시멘트를 규정하고 있습니다. 이 표준의 주요 목표는 콘크리트, 모르타르 및 그라우트 등의 준비에 필요한 CEM II/C-M과 CEM VI에 대한 명확한 지침을 제공하는 것입니다. 이 문서의 주요 강점 중 하나는 포틀랜드 복합 시멘트의 특정 요구 사항을 명시하여 다양한 시멘트 유형의 적용 가능성을 확장하는 데 기여하고 있다는 점입니다. 따라서 CEM II/C-M 및 CEM VI의 적절한 사용을 통해 건축 및 건설 분야에서의 품질과 성능을 향상시킬 수 있습니다. 또한, 이 표준은 EN 197-1에서 제외된 다른 시멘트 유형과의 경계를 명확히 하여 사용자가 혼동하지 않도록 돕고 있습니다. 즉, 일반 시멘트, 저열치 특수 시멘트, 초황산염 시멘트, 칼슘 알루미네이트 시멘트 및 벽돌 시멘트와 같은 다른 표준을 다루지 않음으로써 CEM II/C-M과 CEM VI의 고유한 특성을 부각시키고 있습니다. SIST EN 197-5:2021은 현대 건설 산업에서의 요구 사항을 충족시키기 위해 발전된 시멘트 유형을 다루고 있으며, 포틀랜드 복합 시멘트 및 복합 시멘트의 사용 확대는 지속 가능한 건축 자재 개발에 기여할 것으로 기대됩니다. 이 표준의 적용은 다양한 건설 프로젝트에서 신뢰성을 높이고, 시멘트 품질의 일관성을 유지하는 데 중요한 역할을 할 것입니다.

The standard EN 197-5:2021 focuses on the specifications and guidelines for Portland-composite cement CEM II/C-M and Composite cement CEM VI. This document fills a crucial gap by addressing two types of cement that are not covered under EN 197-1, specifically designed for the preparation of concrete, mortar, and grout, among other applications. One of the notable strengths of EN 197-5:2021 is its targeted scope, which provides clarity and detailed specifications for the mentioned cement types. This ensures manufacturers and users have relevant guidelines that adhere to quality standards specific to Portland-composite cement and Composite cement. The alignment with industry needs enhances the overall relevance of this standard, contributing to improved consistency in cement products used in construction. Moreover, the exclusion of other types of cement such as common cement, very low heat special cement, supersulfated cement, calcium aluminate cement, and masonry cement underscores the standard's focused approach. By not overlapping with EN 197-1 and other standards, EN 197-5:2021 has established its own niche that serves both manufacturers and practitioners in the construction industry effectively. In summary, EN 197-5:2021 is a critical addition to the body of cement standards, emphasizing its significance in promoting high-quality, specific cement products while ensuring they meet the necessary performance criteria for various construction applications.
