BS EN 934-2:2001

This British Standard, having been prepared under the direction of the Sector Policy and Strategy Committee for Building and Civil

Engineering, was published under the authority of the Standards Policy and Strategy Committee on

19 September 2001 © BSI 2006

National foreword

This British Standard is the official English language version of

EN 934-2:2001, including amendments A1:2004 and A2:2005. It supersedes BS EN 934-2:1998 which is withdrawn.

The start and finish of text introduced or altered by CEN amendment is indicated in the text by tags !". Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by !".

EN 934-2:2001 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M128. Products related to concrete, mortar and grout, given under the EU

Construction Products Directive (89/106/EEC), and intended to lead to CE marking. The date of applicability of EN 934-2:2001 as a “harmonized”

European Standard, i.e. 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.

EN 934-2:2001 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 934-2:2001 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. In the UK, the corresponding national standards are:

As these corresponding national standards have already been amended following partial replacement by EN 934-2:1997 and EN 934-6:2000, it has been decided by the responsible BSI subcommittee (B/517/3) that, in the UK, the full 21 month transition period is unnecessary. Instead, only the nominal nine month transition period, set aside to allow required changes to national regulations to be made, is necessary. Based on this nominal nine month transition period BS 5075-1:1982 and BS 5075-3:1985 would be withdrawn in May 2002.

NOTE This date is approximate. Users of this standard should contact BSI Customer Services for confirmation of withdrawal.

The UK participation in its preparation was entrusted by Technical Committee B/517, Concrete, to Subcommittee B/517/3, Admixtures, which has the

responsibility to:

A list of organizations represented on this subcommittee can be obtained on request to its secretary.

Additional information

Attention is drawn to the fact that the requirements for admixtures covered by EN 934-2:1997 are unchanged in EN 934-2:2001. However, EN 934-2:2001 also includes requirements for dual function admixtures not covered by

EN 934-2:1997.

Attention is also drawn to the requirements for corrosion behaviour in Table 1 (item number 10) and Table ZA.1. It states that until there is an accepted European Standard, the national regulations in place of use apply. As the UK has no national regulations in respect of this characteristic, then no testing is required for products sold in the UK and it is acceptable to record “no

performance determined” (NPD), with regard to this characteristic, in the information accompanying the CE marking. However, if the product is to be placed on the market in EU or EFTA member states where there are national regulations for this characteristic, then testing is required in accordance with those regulations.

1 Scope

This European Standard specifies definitions and requirements for admixtures for use in concrete.

It covers admixtures for plain, reinforced and prestressed concrete which are used in site mixed, ready mixed concrete and precast concrete.

The performance requirements in this standard apply to admixtures used in concrete of normal consistence. They may not be applicable to admixtures intended for other types of concrete such as semi-dry and earth moist mixes. Provisions governing the practical application of admixtures in the production of concrete, i. e. requirements concerning composition, mixing, placing, curing etc. of concrete containing admixtures are not part of this standard.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

8 Marking and labelling

8.1 General

When admixtures for concrete are supplied in containers they shall be clearly marked with the relevant information. When the material is supplied into a bulk container at the point of delivery, the same information shall be provided in writing at the time of delivery.

NOTE For CE-marking and labelling see ZA.3.

8.2 Designation of admixtures

Admixtures for concrete shall be designated by:

a) Name of type of admixture in the language of one member country, b) Number of standard: EN 934-2,

c) Code, to identify the type of the admixture, consisting of the number of this standard and the number of the table which gives the additional performance requirements for the particular type of admixture. Where the performance requirements are included in two tables both table numbers shall be included.

EXAMPLE High range water reducing/super plasticizing admixture for concrete; EN 934-2: T3.1/3.2

8.3 Additional Information

a) batch number and production plant;

b) a summary of storage requirements including any special requirements on storage life which shall be clearly marked, e. g.: This admixture shall not be taken to comply with EN 934-2 after "date";

c) instructions for homogenisation before use, when necessary;

d) instructions for use and any necessary safety precautions, e. g. if caustic, toxic or corrosive; e) the manufacturer s recommended range of dosage.

Annex ZA

(informative)

Provisions for the CE marking of admixtures for concrete under the EU Construction Products Directive

ZA.1 Clauses of this European Standard addressing the provisions of the EU Construction Products Directive

This European Standard and this annex ZA have been prepared under a mandate1)_{given to CEN by the European}

Commission and the European Free Trade Association.

The clauses of this European Standard shown in Table ZA.1 meet the requirements of this mandate given under the EU Construction Products Directive (89/106/EEC).

Compliance with this annex ZA confers a presumption of fitness of the admixtures for concrete covered herein for the intended uses under consideration in Table ZA.1.

WARNING Other requirements and other EU Directives, not affecting the fitness for intended uses, can be

applicable to the admixtures for concrete falling within the scope of this annex.

NOTE 1 There may be other requirements, relating to dangerous substances applicable to the products falling within its scope of this standard (e. g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Products Directive, these requirements need also to be complied with, when and where they apply.

NOTE 2 An informative database of European and national provision on dangerous substances is available at the construction web site on EUROPA (CREATE, accessed through http://europa.eu.int).

This annex establishes both the conditions for the CE-marking of the construction products intended for the uses indicated in Table ZA.1 and the relevant clauses applicable.

The scope of this annex is defined by Table ZA.1.
