Foreword
This European Standard has been prepared by Technical Committee CEN/TC 51, Cement and building limes, the Secretariat of which is held by IBN.This European Standard replaces ENV 197-1:1992历史是个什么玩意儿
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorment, at the latest by December 2000, and conflicting national standards shall be withdrawn at the latest by December 2000.
The 1992 version was modified by application of PNE rules, introduction of a revid clau 9, prepared by CEN/TC 51/WG 13, and by taking into account the results of a CEN/TC 51 enquiry in 1995 and a CEN enquiry in 1998.!The amendment A1:2004 contained the low heat common cement
s."EN 197-1 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports esntial requirements of EU Directive(s).For relationship with EU Directive(s), e informative annex ZA,which is an integral part of EN 197-1.
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 TC 51 was entrusted with the task of preparing a cement standard for the countries of Western Europe, comprising the EEC and EFTA members.
A first enquiry initiated by CEN/TC 51 in the mid-venties identified at that time nearly 20 different kinds of cement, which had all been standardized on a national basis and which had proved satisfactory in common or special fields of application under local conditions.The evaluation of the enquiry showed that different sources of raw materials, different climatic conditions and different social/cultural attitudes have established a typical architecture with different building techniques in the different regions of Western Europe which led to the great variety of kinds of cement.The same or similar cement may be ud in very different structures with different types of application and with substantially different requirements regarding its performance under the respective climatic condition
s.
When CEN/TC 51 became aware of this situation, it decided in the early eighties to include in the standard for cement only tho cements which are intended for u in any plain and reinforced concrete and which are familiar in most countries in Western Europe becau they have been produced and ud in the countries for many years. The view of CEN/TC 51 was then that the more regional cements should continue to be standardized at the national level. The 1989 draft for the standard for cement followed this approach, but did not achieve the majority necessary for acceptance becau a few countries wanted to incorporate all their nationally standardized cements and becau the EU Construction Products Directive (89/106/EEC) requires the incorporation of all traditional and well tried cements in order to remove technical barriers to trade in the construction field.
There are as yet no criteria "traditional" and "well tried". A cond enquiry initiated by obvious that some of the described as traditional by the respective national standardization bodies have been produced and ud for decades so that their durability performance has been proved in practice. In contrast,there are some cements, also regarded as traditional and well tried which have been produced only for a few years and have been standardized nationally for only one or two years.

%Amendment A3:2007 contains the modified requirements for fly ash as a cement constituent.&
In view of the large number of different cements involved, it was considered necessary to parate the "common cements"from special tho with additional or special properties. The purpo 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 low heat of hydration " which are described by the respective national standardization bodies within CEN as traditional and well tried. Types bad on composition and a classification bad on strength have been introduced in order to take into account the different cements included. The hardening of the cements mainly hydration of calcium silicates. Common cements with The requirements in EN on the results of tests on cement in accordance with EN 196-1, -2, -3, -5, -6, -7!-8, -9" and -21. The scheme for the evaluation of conformity of common cements !and common cements with low heat of hydration "is specified in EN 197-2. Annex A is informative.
According to the CEN/CENELEC Internal Regulations,the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany,Greece,Iceland, Ireland, Italy, Luxembourg,Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
It is recognized that different cements have different properties and performance. Tho
performance tests now available (i.e. tting time, strength, !soundness and heat of hydration)", have been included in EN 197-1. 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 u.
1 Scope
EN 197-1 defines and gives the specifications of 27 distinct common cement products and their constituents.The definition of each cement includes the proportions in which the constituents are to be combined to produce the distinct products in a range of six strength class.The definition also includes requirements the constituents have to meet and the mechanical, physical and chemical !including, where appropriate, heat of hydration requirements " of the 27 products and strength class. EN 197-1 also states the conformity criteria and the related rules. Necessary durability requirements are also given.
NOTE 1:In addition to the specified requirements, an exchange of additional information between the cement
manufacturer and ur 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 ud to refer only to common cements unless otherwi specified.
