1、BRITISH STANDARD BS EN 197-1:2000 Incorporating amendments nos. 1 and 2 Cement Part 1: Composition, specifications and conformity criteria for common cements The European Standard EN 197-1:2000, incorporating amendments A1:2004 and A3:2007, has the status of a British Standard ICS 91.100.10 ? BS EN
2、197-1:2000 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 9 July 2004 BSI 2007 ISBN 978 0 580 58045 1 National foreword This British Standard is the UK implementation of the harmonized European Standard EN 197-1:2000, incorporating amendment
3、s A1:2004 and A3:2007. This British Standard includes national annexes that provide additional information and guidance to complement EN 197-1. It converts and supersedes DD ENV 197-1:1995 which is withdrawn. The start and finish of text introduced or altered by amendment is indicated in the text by
4、 tags !“. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by !“. The UK participation in its preparation was entrusted by Technical Committee B/516, Cements and lime, to Subcommittee B/516/6, Cement specifications.
5、 A list of organizations represented on this subcommittee can be obtained on request to its secretary. This European Standard is subject to transitional arrangements agreed under a Commission mandate which is intended to lead to CE marking in support of the Construction Products Directive. In order
6、to allow for any changes in national regulations, the Member States have agreed a transition period of 21 months for the co-existence of the British Standards listed below and EN 197-1. At the end of this period, the British Standards listed below will be withdrawn, notification of which will be mad

BS 12:1996Specification for Portland cement; BS 4246:1996 Specification for high slag blastfurnace cement; BS 6588:1996 Specification for Portland pulverized-fuel ash cements; BS 7583:1996 Specification for Portland limestone cement. Common cements conforming to this standard,
8、 where the intended use is for the preparation of concrete, mortar, grout, other mixes for construction and for the manufacture of construction products, have been mandated by the European Commission to be specified under a system of attestation of conformity (see annex ZA). Attestation of conformit
9、y is a legal means for demonstrating that a product meets the requirements of a harmonized European technical specification, as defined in the Construction Products Directive (89/106/EEC). In the case of a system 1+, it is supported by an EC certificate of conformity, issued by an EU notified body,
10、enabling the manufacturer to issue an EC declaration of conformity and to affix the minimum legal health, safety and environmental requirements in the EU Member States, it is not a quality mark.

11、eptember 2007See national foreword BS EN 197-1:2000 BSI 2007 iii The detailed requirements for evaluating the conformity of common cements with this standard, including certification of conformity by a third party, are given in BS EN 197-2:2000, Cement Part 2: Conformity evaluation. In addition, the
12、se same provisions describe all the tasks that will be required of the manufacturer and notified body for demonstrating legal attestation of conformity to a system 1+. This British Standard forms a part of a group of related construction standards, which will include design and construction in concr
13、ete, standardized within the countries of the CEN members. The standards will include Part 1 of Eurocode 2 (EN 1992-1) for the design of concrete structures, EN 206-1, and its associated UK complementary British Standard (BS 8500), for the specifications and associated test methods for the constitue
14、nt materials of concrete, including the BS EN 196 series of test methods for cement. This British Standard does not include in its scope: the additional special properties of low heat Portland cement, conforming to BS 1370 or of sulfate-resisting Portland cement, conforming to BS 4027; or high slag
15、blastfurnace cement, previously specified in BS 4246 or the low early strength classes of Portland blastfurnace cements, specified in BS 146, or pozzolanic pulverized-fuel ash cement, conforming to BS 6610; or other types of cement whose hardening is not primarily due to the hydration of calcium sil
16、icates, i.e. high alumina cement, conforming to BS 915-1, and supersulfated cement, conforming to BS 4248. It is intended that cements from within this range will be specified in further parts of BS EN 197 or in other standards. National annex NA (informative) compares the notation for common cement
17、s given in Table 1 of this British Standard, with the notation in those British Standard specifications listed previously and which are to be withdrawn after the period of co-existence, and those still current. Table NA.1 in the national annex provides a means by which users of related construction
18、standards that contain lists of permitted cements conforming to British Standards which are to be withdrawn can select common cements (by name and notation) that are their equivalent. This assessment of equivalence will only be necessary for a limited period. It arises because the British Standards
19、Institution has agreed with industry that amendments to cement-related construction standards will not be issued to reflect the notation in use for common cements. When, however, the majority of such British Standards have themselves been replaced by European Standards the need to assess equivalence
20、 will cease. National annex NB (informative) details the exchange of additional information between the cement manufacturer and use including the provision of information for alkali contents. National annex NC (informative) gives recommendations for sampling and testing for acceptance inspection at
21、delivery. This British Standard does not give fineness limits. National annex ND (informative) describes how specialist users in the UK can order a controlled fineness CEM I cement having a small agreed range of fineness. It also includes provisions for pigmented cement. National annex NE (normative
22、) gives a requirement, which is permitted to be standardized on a national basis, for the loss on ignition property of a siliceous fly ash constituent. National annex NF (informative) gives guidance on the general use of common cements including health and safety aspects. National annex NG (informat
23、ive) lists publications referred to in the national annexes. UK purchasers are recommended to specify common cement which has been manufactured and supplied to a nationally recognized third party product quality certification scheme. This publication does not purport to include all the necessary pro
24、visions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. blank EUROPEAN STANDARD NORME EUROPENNE EUROPISCHE NORM EN 197-1 June 2000 ICS 91.100.10 Supersedes ENV 197-1:1992 English version Cement - Part

33、n at the latest by December 2000. The 1992 version was modified by application of PNE rules, introduction of a revised clause 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
34、 common cements.“ EN 197-1 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 EN 197-1
35、. 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 preparin
36、g 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-seventies identified at that time nearly 20 different kinds of cement, which had all been standardized on a national basis and which had proved satisfactory
37、 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 di
38、fferent regions of Western Europe which led to the great variety of kinds of cement. The same or similar cement may be used in very different structures with different types of application and with substantially different requirements regarding its performance under the respective climatic condition
39、s. When CEN/TC 51 became aware of this situation, it decided in the early eighties 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 u
40、sed in these 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 because a few co
41、untries wanted to incorporate all their nationally standardized cements and because 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 c
42、riteria for the descriptions “traditional“ and “well tried“. A second enquiry initiated by CEN/TC 51 in 1990 revealed a further 50 cements standardized nationally. It became obvious that some of the cements described as traditional by the respective national standardization bodies have been produced
43、 and used 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.

44、%Amendment A3:2007 contains the modified requirements for fly ash as a cement constituent. the latter may have, in addition, hydraulic properties. The loss on ignition of fly ash determined in a) 0 % to 5,0 % by mass b) 2,0 % to 7,0 % by mass c) 4,0 % to 9,0 % by mass The upper limit of loss on igni
45、tion of the fly ash used as a main constituent for the production of cement as main constituent shall be stated on its packaging and/or delivery note. (3) The use of fly ash with loss on ignition up to 7,0 % or up to 9,0 % by mass is permitted provided that particular requirements for durability, es
46、pecially frost resistance, and for compatibility with admixtures are met according to the appropriate standards and/or regulations for concrete or mortar in the place of use. NOTE 2 The purpose of the requirement for the loss on ignition is to limit the residue of unburnt carbon in the fly ash. It i
47、s sufficient, therefore, to show, through direct measurement of unburnt carbon residue, that the content of unburnt carbon falls within the limits specified above. The content of unburnt carbon is determined in accordance with ISO 10694. - L: shall not exceed 0,50 % by mass. 5.2.7 Silica fume (D) Si
48、lica fume originates from the reduction of high purity quartz with coal in electric arc furnaces in the production of silicon and ferrosilicon alloys and consists of very fine spherical particles containing at least 85 % by mass of amorphous silicon dioxide. Silica fume shall meet the following requ
49、irements: a) The loss on ignition shall not exceed 4,0 % by mass determined in accordance with EN 196-2 but using an ignition time of 1 h. b) The specific surface (BET) of the untreated silica fume shall be at least 15,0 m2/g when tested in accordance with ISO 9277. For intergrinding with clinker and calcium sulfate the silica fume may be in its original state or compacted or pelletized (with water). 5.3 Minor additional constituents Minor additional constit
