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 A2, if approved, will modify the European Standard EN 197-1:2000. 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

Foreword
This document (EN 197-1:2000/prA2:2006) 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 197-1:2000 to cover the optional property of sulfate
resistance for common cement. The further technical content of EN 197-1:2000 has not been changed.

Amendments 2
Foreword
Add (modification is underlined):
th
4 paragraph:
The amendment A2:2006 contained the sulfate resisting common cements.
th
11 paragraph:
In view of the large number of different cements involved, it was considered necessary to separate the “common
cements” from special cements i.e. those with additional or special properties. The purpose of EN 197-1 is to
specify the composition, requirements and conformity criteria for the common cements. This includes all common
cements and common cements with adequate sulfate resistance which are described by the respective national
standardisation bodies within CEN as traditional and well tried. Types based on composition and a classification
based on strength have been introduced in order to take into account the different cements included. The
hardening of these cements mainly depends on the hydration of calcium silicates. Common cements with special
properties as well as cements with different hardening processes will be included in further parts of this European
Standard or in further European Standards respectively.
th
12 paragraph:
The requirements in EN 197-1 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 common cements and common cements with
adequate sulfate resistance is specified in EN 197-2.
th
13 paragraph:
In order to find out whether cement with high sulfate resistance should be taken into account in EN 197-1, 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 have been classified in the EU Member States as sulfate resisting. This is due to the
different geographical and climatic conditions under which sulfate attacks on mortar and concrete occur at the
place of use and the traditionally different rules governing the production and use of sulfate 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 197-1 for common 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 common 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 sulfate conditions.
Based on the above results common cement types to be harmonized on European level have been chosen. The
predominant part of the common 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.

EN 197-1:2000/prA2:2006 (E)
1 Scope
Add (modification is underlined):
EN 197-1 defines and gives the specifications of 27 distinct common cement products and 7 sulfate resisting
common 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 six strength classes. The definition
also includes requirements the constituents have to meet and the mechanical, physical and chemical requirements
of these products and strength classes. EN 197-1 also states the conformity criteria and the related rules.
Necessary durability requirements are also given.
In addition to those sulfate resisting cements defined in the present document, other cements conforming either to
EN 197-1 or to national standards have been locally demonstrated to have sulfate resisting properties. These
cements may be used in sulfate aggressive environments if permitted in national provisions valid in the place of the
construction site. These cements may not bear the CE Marking for their sulfate resistance property.
NOTE 1 In addition to the specified requirements, an exchange of additional information between the cement manufacturer
and user may be helpful. The procedures for such an exchange are not within the scope of EN 197-1 but should be dealt with in
accordance with national standards or regulations or may be agreed between the parties concerned.
NOTE 2 The word “cement” in EN 197-1 is used to refer only to common cements unless otherwise specified.
