No. Date Comments 16763 Corrigend um No. 1 31 October 2020 Correction to national foreword Licensed Copy: London South Bank University, London South Bank University, Wed Jan 10 19:37:14 GMT+00:00 2007, Uncontrolled Copy, (c) BSI BS EN 151671:2020 National foreword This British Standard was published by BSI. It is the UK implementation of EN 151671:2020. Together with BS EN 151672 it supersedes BS 6699:1992 which will be withdrawn on 1 May 2020. EN 151671 is a candidate ―harmonized‖ European standard and fully takes into account the requirements of the European Commission Mandate M/128, Products related to concrete, mort ar and grout, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 151671 as a harmonized European standard, . the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. The Commission in consultation with Member States has agreed a transition period for the coexistence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will prise a period, usually nine months, after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this coexistence period, the national standard will be withdrawn. In the UK, the corresponding national standard is: — BS 6699: 1992, Specification for ground granulated blast furnace slag for use with Portland cement, and based on this transition period of 21 months, BS 6699:1992 will be withdrawn on 1 May 2020 NOTE This date is appro xim a te. Users of this standa rd should contact BSI Custom er Services for confirm ation of withdrawal. The UK participation in its preparation was entrusted by Technical Committee B/517, Cement and lime, to Submittee B/517/4, Additions for concrete. A list of anizations represented on B/517/4 can be obtained on request to its secretary. Additional information In most cases, ground granulated blastfurnace slag that conforms to BS 6699 will also conform to BS EN 15671, and viceversa. The requirements for: fineness, glass content, sulfide, sulfate, lossonignition, chloride and moisture content are essentially identical. The limit in BS EN 151671 for magnesia is higher than in BS 6699. Unlike BS 6699, BS EN 151671 contains no limits for mangan ese, insoluble residue or soundness. The 7 and 28day strength requirements in BS EN 151671 are expressed as ??activity indices‘‘ (% of strength of test cement) and are based on tests with 50% ground granulated blastfurnace slag (pared to 70% ground granulated blastfurnace slag in BS 6699), and the strength requirements cannot be directly pared. Comparative testing suggests that the strength requirements in BS EN 151671 are slightly less onerous than those in BS 6699. BS EN 151671 contains a requirement for the initial setting time to be not more than twice as long as the test cement on its own, whereas the requirement in BS 6699 is for the setting time to be not less than that of the test cement.

Compliance with a British Standard cannot confer immunity from legal obligations. This British Standard was published under the authority of the Standards Policy and Strategy Committee on 31 Oct ober 2020 169。ENNE EUROP196。 English Version Ground granulated blast furnace slag for use in concrete, mortar and grout Part 1: Definitions, specifications and conformity criteria Laitier granul233。ton, mortier et coulis Partie 1: D233。res de conformit233。ttensandmehl zur Verwendung in Beton, M246。rtel Teil 1: Definitionen, Anforderungen und Konformit228。 EUR O P 201。 I S C H ES KOM I TE
