Foreword
This document (prEN 197-1:2014) has been prepared by Technical Committee CEN/TC 51 “Cement and building
limes”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 197-1:2011.
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 Regulation (EU) No. 305/2011.
For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this
document.
Annexes A and ZA are informative.
The preparation of a standard for cement was initiated by the European Economic Community (EEC) in 1969 and, at the
request of a member state later in 1973, the work was given to the European Committee for Standardization (CEN). The
Technical Committee CEN/TC 51 was entrusted with the task of preparing a cement standard for the countries of
Western Europe, comprising the EEC and EFTA members.
In the early eighties, CEN/TC 51 decided to include in the standard for cement only those cements which are intended
for use in any plain and reinforced concrete and which are familiar in most countries in Western Europe because they
have been produced and used in these countries for many years. The EU Construction Products Directive (89/106/EEC)
required the incorporation of all traditional and well-tried cements in order to remove technical barriers to trade in the
construction field. There are currently no criteria for the descriptions "traditional" and "well tried" and it was considered
necessary to separate the “common cements” from special cements, i.e. those with additional or special properties.
The requirements in this standard are based on the results of tests on cement in accordance with EN 196-1, EN 196-2,
EN 196-3, EN 196-5, EN 196-6, EN 196-7, EN 196-8, and EN 196-9. The scheme for the evaluation of conformity of
common cements including common cements with low heat of hydration and common cements generally accepted as
being sulfate resisting are specified in EN 197-2.
In 2006, CEN/TC 51 started to investigate the possible standardization of new cements produced with traditional
constituent materials and manufacturing methods, but according to composition limits out of the limits defined so far in
EN 197-1. Based on the results of a pre-normative study presented in 2011, new cements containing Portland cement
clinker and, as other main constituents, limestone, granulated blast furnace slag or siliceous fly ash or natural
pozzolana, have been standardized in this document as CEM II/C and CEM VI.
The strength attained at twenty-eight days is the important criterion in classifying cement for most uses. In order to
achieve a specific strength class at twenty-eight days the early strength, at two days or at seven days, can vary and
some types of cement may not attain the minimum early strengths specified in EN 197-1 for common cements.
The heat of hydration is linked to the early reactivity and lower early strengths indicate lower heat evolution and lower
temperatures in concrete. For these cements additional precautions in use can be necessary to ensure adequate curing
and safety in construction.
The purpose of this standard is to specify the composition requirements and conformity requirements for common
cements, including common cements with low heat of hydration and common cements with adequate sulfate resistance
as well as low early strength blast furnace cements and low early strength blast furnace cements with low heat of
hydration.
Cement types and strength classes defined in this European Standard allow the specifier and/or the user to fulfil
objectives of sustainability for cement based constructions. Cement types produced by using constituents listed and
defined in Clause 5 allow the manufacturer to minimize the use of natural resources in accordance with local conditions
of production.

Introduction
It is recognized that different cements have different properties and performance. Those performance tests now
available (i.e. setting time, strength, soundness and heat of hydration), have been included in this standard. In addition,
work is being carried out by CEN/TC 51 to identify any additional tests which are needed to specify further performance
characteristics of cement. Until further performance tests are available it is necessary that the choice of cement,
especially the type and/or strength class in relation to the requirements for durability depending on exposure class and
type of construction in which it is incorporated, follows the appropriate standards and/or regulations for concrete or
mortar valid in the place of use.

1 Scope
This European Standard defines and gives the specifications of 35 distinct common cements, 7 sulfate resisting
common cements as well as 3 distinct low early strength blast furnace cements and 2 sulfate resisting low early strength
blast furnace 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 nine strength classes. The definition
also includes requirements which the constituents have to meet. It also includes mechanical, physical, and chemical
requirements. Furthermore, this standard 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 this
standard or to other standards, European or national, have been nationally demonstrated to have sulfate resisting
properties. These cements which are listed in Annex A, are considered by different CEN Member countries as sulfate
resisting within the limits of their territory.
NOTE 1 In addition to the specified requirements, an exchange of additional information between the cement manufacturer and
user can be helpful. The procedures f
