17、the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2008, and conflicting national standards shall be withdrawn at the latest by July 2009. Attention is
18、drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the Eur
19、opean Free Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard is a part of the series EN 934 Admixtures for concrete, mortar and grout which is
20、comprised of the following parts: Part 1: Common requirements1)Part 2: Concrete admixtures Definitions, requirements, conformity, marking and labelling Part 3: Admixtures for masonry mortar Definitions, requirements, conformity, marking and labelling Part 4: Admixtures for grout for prestressing ten

This European Standard is used with the standards of the series EN
22、 480 which comprises test methods for admixtures. Subject to the provisions in EN 14487-1, Sprayed concrete Part 1: Definitions, specifications and conformity admixtures covered by EN 934-2 may also be considered for the use in sprayed concrete. A previous draft of EN 934-5 had been submitted to For
23、mal Vote in 2004 and had formally passed the vote by majority of CEN-members in 2005. Together with this vote, however, some members presented severe technical comments which were agreed upon by the relevant CEN/TC 104/SC 3 to be taken into account by an amendment. In order to avoid the need of usin
24、g two separate papers in practice, CEN/TC 104 decided, however, not to publish the agreed document but to submit a further consolidated version including the amended issues to UAP, which finally should be published. The amendments to the final draft prEN 934-5:2004-11 are the following: - Table 1: r

DIN EN 934-5:2008-02 EN 934-5:2007 (E) 5 1 Scope This European Standard defines and specifies requirements and conformity for admixtures specifically intended for use in sprayed concrete. The types of admixtures cove
29、red are: set accelerating and non-alkaline set accelerating admixtures; consistence control admixtures; bond improving admixtures. Provisions governing the practical application of these admixtures in the production of sprayed concrete are not part of this European Standard. 2 Normative references T
