EN 206:2013 (E) 4 Foreword This document (EN 206:2013) has been prepared by Technical Committee CEN/TC 104 “Concrete and related 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of an identical text or by endorsement, at the latest by June 2014 and conflicting national standards shall be withdrawn at the latest by June 2014. Attention is 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. Based on a CEN/BT Decision (DECISION BT 42/2013) EN 12620:2013 was withdrawn. Therefore, this document has been aligned with the specifications given in EN 12620:2002+A1:2008. As soon as CEN/TC 154 publishes a new version of EN 12620, CEN/TC 104 intends to amend EN 206.
This document supersedes EN 206-1:2000 and EN 206-9:2010. In particular, the following main items were subject to revision when preparing this European Standard: a) adding application rules for fibre concrete and concrete with recycled aggregates; b) revising k-value concept for fly ash and silica fume and adding new rules for ground granulated blast furnace slag; c) introduction of principles for the performance concepts for the use of additions, e.g. equivalent concrete performance concept and equivalent performance of combinations concept; d) revising and adding new concepts for the conformity assessment; e) including EN 206-9 “Additional rules for self-compacting concrete (SCC)”; f) including additional requirements for concrete for special geotechnical works (Annex D). NOTE Annex D was jointly prepared by CEN/TC 104 and CEN/TC 288.

SIST EN 206:2013
EN 206:2013 (E) 6 Introduction This European Standard will be applied 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 introduced to cover these situations. Where such general solutions were not possible, the relevant clauses contain permission for the application of provisions valid in the place of use of the concrete. This European Standard incorporates rules for the use of constituents that are covered by European Standards. Constituents not covered by European Standards may be used in accordance with provisions valid in the place of use of the concrete. If the concrete is in conformity with the limiting values, the concrete in the structure is deemed to satisfy the durability requirements for the intended use in the specific environmental condition, provided: the appropriate exposure classes were selected; the concrete has the minimum cover to reinforcement in accordance with the relevant design standard required for the specific environmental condition, e.g. EN 1992-1-1; the concrete is properly placed, compacted and cured, e.g. in accordance with EN 13670 or other relevant standards; the appropriate maintenance is applied during the working life. Performance based concepts as alternatives to the concept of limiting values are under development.
Concrete conforming to this European Standard may be assumed to satisfy the basic requirements for materials to be used in all three Execution Classes as defined in EN 13670. This European Standard defines tasks for the specifier, producer and user. For example, the specifier is responsible for the specification of concrete, Clause 6, and the producer is responsible for conformity and production control, Clauses 8 and 9. 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-contractor. 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 European Standard, this final compilation is known as the “specification of concrete”. Conversely, the specifier, producer and user may be the same party (e.g. a precast concrete manufacturer or a contractor doing design and build). In the case of ready- mixed concrete, the purchaser of the fresh concrete is the specifier who gives the specification of concrete to the producer.
This European Standard also covers the necessary exchange of information between the different parties. Contractual matters are not addressed. Where responsibilities are given for parties involved, these are technical responsibilities.
Notes and footnotes in tables of this standard are normative unless stated otherwise; other notes and footnotes are informative. Further explanations and guidance on the application of this standard are given in other documents, such as CEN Technical Reports. SIST EN 206:2013
EN 206:2013 (E) 7 1 Scope (1) This European Standard applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures. (2) The concrete under this European Standard can be: normal-weight, heavy-weight and light-weight;
mixed on site, ready-mixed or produced in a plant for precast concrete products;
compacted or self-compacting to retain no appreciable amount of entrapped air other than entrained air. (3) This standard specifies requirements for: the constituents of concrete; the properties of fresh and hardened concrete and their verification; the limitations for concrete composition; the specification of concrete; the delivery of fresh concrete; the production control procedures; the conformity criteria and evaluation of conformity. (4) Other European Standards for specific products e.g. precast products or for processes within the field of the scope of this standard may require or permit deviations. (5) Additional or different requirements may be given for specific applications in other European Standards, for example: concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to EN 13877–1); special technologies (e.g. sprayed concrete according to EN 14487). (6) Supplementing requirements or different testing procedures may be specified for specific types of concrete and applications, for example: concrete for massive structures (e.g. dams); dry mixed concrete; concrete with a Dmax of 4 mm or less (mortar); self-compacting concretes (SCC) containing lightweight or heavy-weight aggregates or fibres; concrete with open structure (e. g. pervious concrete for drainage).

Evropski standard EN 206:2013 je pripravil tehnični odbor Evropskega komiteja za standardizacijo
CEN/TC 104 Beton in sorodni proizvodi. Slovenski nacionalni standard SIST EN 206:2013 je prevod
evropskega standarda EN 206:2013. V primeru spora glede besedila slovenskega prevoda v tem
standardu je odločilen izvirni evropski standard v angleškem jeziku.
Odločitev za izdajo tega standarda je dne 23. septembra 2013 sprejel SIST/TC BBB Beton, armirani in
prednapeti beton.

SIST EN 206 : 2013
Uvod
Ta evropski standard se bo uporabljal v različnih podnebnih in geografskih razmerah, pri različnih ravneh
zaščite ter ob različnih, že uveljavljenih regionalnih tradicijah in izkušnjah. To stanje je upoštevano z
vpeljavo razredov za lastnosti betonov. Če takšne splošne rešitve niso bile mogoče, je v ustreznih točkah
dovoljena uporaba nacionalnih standardov ali predpisov, veljavnih v kraju uporabe betona.
Ta evropski standard vsebuje pravila za uporabo osnovnih materialov, ki jih obravnavajo evropski
standardi. Materiali, za katere ni evropskih standardov, se lahko uporabljajo v skladu s predpisi, ki
veljajo v kraju vgradnje betona.
Če je beton skladen z mejnimi vrednostmi, se šteje, da vgrajeni beton izpolnjuje trajnostne zahteve za
predvideno uporabo v specifičnih okoljskih razmerah, ob predpostavki, da:
– so izbrane ustrezne stopnje izpostavljenosti;
– je najmanjša debelina prekrivnega sloja betona v skladu z ustreznim standardom za projektiranje,
ki se zahteva za posebne okoljske razmere, npr. z EN 1992-1-1;
– je beton ustrezno vgrajen, zgoščen in negovan, npr. v skladu z EN 13670 ali drugimi ustreznimi
standardi;
– je med življenjsko dobo ustrezno vzdrževan.
Koncepti na osnovi enakovrednega obnašanja betona kot alternative h konceptu mejnih vrednosti so v
pripravi.
Za beton, ki je skladen s tem evropskim standardom, se pričakuje, da zadošča osnovnim zahtevam za
materiale, ki se uporabljajo v vseh treh izvedbenih razredih, kot so opredeljeni v EN 13670.
Ta standard opredeljuje naloge izdajatelja specifikacije, proizvajalca in uporabnika. Na primer, izdajatelj
specifikacije je odgovoren za specificiranje betona po poglavju 6, proizvajalec pa za kontrolo skladnosti
in kontrolo proizvodnje po poglavjih 8 in 9. Uporabnik je odgovoren za vgrajevanje betona v konstrukcijo.
V praksi lahko zahteve predpiše več različnih udeležencev v raznih fazah procesa projektiranja in
gradnje, npr. naročnik, projektant, izvajalec del, podizvajalec betonarskih del. Vsak odgovarja za prenos
predpisanih zahtev skupaj z vsemi dodatnimi zahtevami naslednji stranki v verigi, vse do proizvajalca. V
tem standardu je "specifikacija" končni zbir teh zahtev. Obratno je lahko ista stranka izdajatelj
specifikacije, proizvajalec in uporabnik (npr. izvajalec del, ki projektira in gradi). Pri transportnem betonu
je izdajatelj specifikacije kupec svežega betona, dati pa jo mora proizvajalcu.
Ta evropski standard obravnava tudi potrebno izmenjavo informacij med različnimi strankami, ne
obravnava pa pogodbenih zadev. Če so navedene odgovornosti vpletenih strank, so to tehnične
odgovornosti.
Če ni določeno drugače, so v tem standardu opombe in opombe pod preglednicami normativne;
ostale opombe in opombe pod črto pa so informativne.
Nadaljnje razlage in navodila za uporabo tega standarda so dane v drugih dokumentih, kot so npr.
tehnična poročila CEN.

Introduction
This European Standard will be applied 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 introduced to cover these situations. Where such general solutions were not possible,
the relevant clauses contain permission for the application of national standards or provisions valid in the
place of use of the concrete.
This European Standard incorporates rules for the use of constituents that are covered by European
standards. Constituents not covered by European standards may be used in accordance with provisions valid
in the place of use of the concrete.
If the concrete is in conformity with the limiting values, the concrete in the structure is deemed to satisfy the
durability requirements for the intended use in the specific environmental condition, provided:
the appropriate exposure classes were selected;
the concrete has the minimum cover to reinforcement in accordance with the relevant design standard
required for the specific environmental condition, e.g. EN 1992-1-1;
the concrete is properly placed, compacted and cured, e.g. in accordance with EN 13670 or other
relevant standards;
the appropriate maintenance is applied during the working life.
Performance based concepts as alternative to the concept of limiting values are under development.
Concrete conforming to EN 206 may be assumed to satisfy the basic requirements for materials to be
used in all three Execution Classes as defined in EN 13670.
This European Standard defines tasks for the specifier, producer and user. For example, the specifier is
responsible for the specification of concrete, clause 6, and the producer is responsible for conformity and
production control, clauses 8 and 9. 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-contractor. 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 European Standard, this final compilation
is known as the “specification”. Conversely, the specifier, producer and user may be the same party (e.g. a
precast concrete manufacturer or a contractor doing design and build). In the case of ready mixed concrete,
the purchaser of the fresh concrete is the specifier and has to give the specification to the producer.
This European Standard also covers the necessary exchange of information between the different parties.
Contractual matters are not addressed. Where responsibilities are given for parties involved, these are
technical responsibilities.
Notes and footnotes in tables of this Standard are normative unless stated otherwise; other notes and
footnotes are informative.
Further explanations and guidance on the application of this Standard are given in other documents, such as
CEN Technical Reports.

the scope of this Standard may require or permit deviations.
(5) Additional or different requirements may be given for specific applications or in other European standards,
for example:
concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to
EN 13877-1);
special technologies (e.g. sprayed concrete according to EN 14487).
