15、d products”, 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of an identical text or by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn at the latest by December
16、 2007. This European Standard has taken EN 206-1 as a basis. Some clauses which apply to sprayed concrete refer to EN 206-1 because of their importance. Other clauses have been modified to meet the specific requirements of sprayed concrete. This European Standard is only operable with product standa
17、rds for constituent materials (i.e. cement, aggregates, additions, admixtures, fibres and mixing water) and related test methods for sprayed concrete which form the package defined below. For this reason, the latest date of withdrawal of national standards (DOW) conflicting with this document is det

23、ngdom. EN 14487-1:2005 (E) 4 Introduction This European Standard will be applied in Europe under different climatic and geographical conditions, different levels of protection and under different, well-established, regional traditions and experience. Classes for concrete properties have been introdu
24、ced to cover this situation. Where such general solutions were not possible, the relevant clauses contain permission for the application of EN 206-1 or other standards valid in place. This European Standard incorporates rules for the use of constituent materials that are covered by European Standard
25、s. Other by-products of industrial processes, recycled materials etc. are in current use based on local experience. Until European specifications for these materials are available, this document will not provide rules for their use, but instead refers to the recommendations given in EN 206-1 to appl
26、y national standards or provisions valid in the place of use of the concrete. This European Standard defines tasks for the specifier, producer and user. For example, the specifier is responsible for the specification of concrete, Clauses 5 and 6 and the producer is responsible for conformity and pro
27、duction control, Clause 7. The user is responsible for placing the concrete in the structure. In practice there may be several different parties specifying requirements at various stages of the design and construction process e.g. the client, the designer, the contractor, the concreting sub-contract
28、or. Each is responsible for passing the specified requirements, together with any additional requirements, to the next party in the chain until they reach the producer. In the terms of this document, this final compilation is known as the “specification“. Further explanations and guidance on the app
29、lication of this document are given in Annex A. EN 14487-1:2005 (E) 5 1 Scope This European Standard is applicable to sprayed concrete, to be used for repair and upgrading of structures, for new structures and for strengthening of ground. This European Standard covers: classification related to cons
30、istence of wet mix; environmental exposure classes; young, hardened and fibre reinforced concrete; requirements for constituent materials, for concrete composition and for basic mix, for fresh and hardened concrete and all types of fibre reinforced sprayed concrete; specification for designed and pr
31、escribed mixes; conformity. This European Standard is applicable to wet mix as well as dry mix sprayed concrete. The substrates to which sprayed concrete can be applied include: ground (rock and soil); sprayed concrete; different types of formwork; structural components constituted of concrete, maso
32、nry and steel; drainage materials; insulating materials. Additional or different requirements may be needed for applications not within this document, for instance-refractory uses. 2 Normative references The following referenced documents are indispensable for the application of this document.
