14、s British Standard forms a part of a group of related construction standards, which will include design and construction in concrete, 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
15、 its associated UK complementary British Standard (BS 8500), for the specifications and associated test methods for the constituent 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
16、 of low heat Portland cement, conforming to BS 1370 or of sulfate-resisting Portland cement, conforming to BS 4027; or high slag 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
17、 ash cement, conforming to BS 6610; or other types of cement whose hardening is not primarily due to the hydration of calcium silicates, 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 speci
18、fied in further parts of BS EN 197 or in other standards. National annex NA (informative) compares the notation for common cements 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this British Standard, with the notation in those British Standard specifications listed previously and which are to be withdrawn after the period of
19、 co-existence, and those still current. Table NA.1 in the national annex provides a means by which users of related construction standards that contain lists of permitted cements conforming to British Standards which are to be withdrawn can select common cements (by name and notation) that are their
20、 equivalent. This assessment of equivalence will only be necessary for a limited period. It arises because the British Standards 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, h
21、owever, the majority of such British Standards have themselves been replaced by European Standards the need to assess equivalence will cease. National annex NB (informative) details the exchange of additional information between the cement manufacturer and use including the provision of information
22、for alkali contents. National annex NC (informative) gives recommendations for sampling and testing for acceptance inspection at 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
23、 I cement having a small agreed range of fineness. It also includes provisions for pigmented cement. National annex NE (normative) 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 (
24、informative) gives guidance on the general use of common cements including health and safety aspects. National annex NG (informative) lists publications referred to in the national annexes. UK purchasers are recommended to specify common cement which has been manufactured and supplied to a nationall

36、0 B SI 0002-90 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 This European Standard shall be given the status of a national standard, either by pub
37、lication of an identical text or by endorsement, 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 revised clause 9, prepared by CEN/TC 51/WG 13, and by ta
38、king 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 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 re
39、quirements of EU Directive(s). For relationship with EU Directive(s), see 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
40、 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-seventies identified at
41、 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 co
42、nditions 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 used in very different structures with different
43、 types of application and with substantially different requirements regarding its performance under the respective climatic conditions. 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
44、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 view of CEN/TC 51 was then that the more regional cements should continue to be standardized at the national level. The 1989
45、 draft for the standard for cement followed this approach, but did not achieve the majority necessary for acceptance because a few countries wanted to incorporate all their nationally standardized cements and because the EU Construction Products Directive (89/106/EEC) requires the incorporation of a
46、ll traditional and well tried cements in order to remove technical barriers to trade in the construction field. There are as yet no criteria 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
47、became obvious that some of the cements described as traditional by the respective national standardization bodies have been produced 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 trie
48、d which have been produced only for a few years and have been standardized nationally for only one or two years.

49、mon 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 low heat of hydration“ which are described by the respective national standardization bodies within CEN as traditional and well tried. Types based on composition and a classification based on
