Overview

EN 197-4:2004/prA1 is an amendment to the European Standard EN 197-4:2004, developed by CEN/TC 51, which focuses on the composition, specifications, and conformity criteria for low early strength blastfurnace cements. This amendment, titled Amendment A1, introduces specifications for sulfate resisting low early strength blastfurnace cements to enhance durability in sulfate-rich environments. The amendment covers two products in this category-CEM III/B-SR S and CEM III/C-SR S-which are designed to deliver both low early strength and increased sulfate resistance.

Key Topics

• Scope Expansion: Amendment A1 extends EN 197-4 to include sulfate resistance as an optional property for low early strength blastfurnace cements.
• Product Definitions:
  • CEM III/B-SR S: Contains 20–34% clinker and 66–80% granulated blastfurnace slag.
  • CEM III/C-SR S: Contains 5–19% clinker and 81–95% granulated blastfurnace slag.
• Sulfate Resistance: This property is critical for cements used in environments exposed to aggressive sulfate ions, improving concrete durability.
• Composition and Notation: Specifies percentage mass ranges of clinker and slag, with sulfate resisting variants marked by “SR S” in the product notation.
• Testing and Conformity: Cement performance must be verified in accordance with established EN 196 test methods alongside the conformity scheme in EN 197-2.
• Durability and Mechanical Properties: Requirements cover mechanical, physical, and chemical properties, including heat of hydration and strength classification.
• European Market Harmonization: The amendment harmonizes sulfate resistant low early strength blastfurnace cements at the European level while allowing for local variations under national regulations.
• CE Marking: Incorporates requirements for certification and CE marking specific to sulfate resisting cements to ensure consistent quality and regulatory compliance.

Applications

• Construction Materials: Used in manufacturing concrete, mortar, grout, and other mixes for various construction purposes.
• Sulfate-Aggressive Environments: Ideal for structures exposed to high sulfate concentrations such as sewage treatment plants, marine environments, and foundations in sulfate-rich soils.
• Infrastructure Projects: Suitable for durable infrastructure works requiring enhanced resistance against chemical attack without sacrificing early strength performance.
• Sustainable Building Practices: Utilizes large proportions of blastfurnace slag, aligning with sustainable construction goals by reducing clinker content and CO₂ emissions.

Related Standards

• EN 197-1: General standard for common cements specifying composition and conformity.
• EN 197-2: Details the conformity assessment system for cement products.
• EN 196 Series: Specifies test methods for determining various physical and chemical properties of cement.
• EN 934 Series: Addresses admixtures that may be used in conjunction with sulfate resisting blastfurnace cements.
• EU Construction Products Directive (89/106/EEC): Regulatory framework supported by EN 197-4 for CE marking and market surveillance.

This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 51.
This draft amendment A1, if approved, will modify the European Standard EN 197-4:2004. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.
This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status
as the official versions.

Foreword
This document (EN 197-4:2004/prA1:2006) has been prepared by Technical Committee CEN/TC 51 “Cement and
building limes”, the secretariat of which is held by IBN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This Amendment extends the European Standard EN 197-4:2004 to cover the optional property of sulfate
resistance for low early strength blastfurnace cement. The further technical content of EN 197-4:2004 has not been
changed.
The numbering of the clauses refers to EN 197-4:2004.

The amendment A1:2006 contained the sulfate resisting low early strength blastfurnace cements.
th
9 paragraph:
The requirements in EN 197-4 are based on the results of tests on cement in accordance with EN 196-1, -2, -3, -5,
-6, -7, -8, and -9. The scheme for the evaluation of conformity of low early strength blastfurnace cements and low
early strength blastfurnace cements with adequate sulfate resistance is specified in EN 197-2.
th
10 paragraph:
In order to find out whether cement with high sulfate resistance should be taken into account in EN 197, there was
an investigation within CEN/TC 51 comprising all national specifications and recommendations in the European
Union. The review of these investigations led to the following results:
- A wide variety of cements are classified in the EU Member States. This is due to the different geographical and
climatic conditions under which sulphate attacks on mortar and concrete occur at the place of use and the
traditionally different rules governing the production and use of sulphate resistant mortars and concretes.
- Sulfate resistance is an additional property and therefore sulfate resisting cements have first to comply with the
requirements of the standards which define the product, e. g. EN 197-4 low early strength blastfurnace cements.
- The additional requirements to be met by the nationally specified sulfate resisting cements refer to selected
characteristics for which the required limit values are more stringent than those for low early strength blastfurnace
cements.
- Having satisfied the local requirements for various cement types many countries apply further restrictions to the
production of concrete to be used in a sulfate environment, such as minimum cement contents and/or maximum
water/cement ratio that vary depending on the cement type and the type and intensity of the sulphate conditions.
Based on the above results low early strength blastfurnace cements types to be harmonized on European level on
a consensual basis have been chosen. The predominant part of the low early strength blastfurnace cements with
high sulfate resistance in the market is covered by this selection. It was not possible to take into account national
local particularities the use of which is laid down within national application rules and regulations/provisions.

This EN 197-4 defines and gives the specifications of 3 distinct low early strength blastfurnace cement products
and 2 sulfate resisting low early strength blastfurnace cements and their constituents. The definition of each
