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.

Foreword

3 paragraph:
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.
1 Scope
Add (modification is underlined):
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
cement includes the proportions in which the constituents are to be combined to produce these distinct products in
a range of three strength classes. The definition also includes requirements the constituents have to meet and the
mechanical, physical and chemical, including where appropriate, heat of hydration, requirements and strength
classes. This EN 197-4 also states the conformity criteria and the related rules. Necessary durability requirements
are also given.
