Admixtures for concrete, mortar and grout - Part 3: Admixtures for masonry mortar - Definitions, requirements, conformity and marking and labelling

This European Standard defines and specifies the requirements and conformity criteria for admixtures for use in cement based masonry mortar.
It covers two types of admixtures, long term retarding and air entraining/plasticising which are used in ready-mixed and site made masonry mortars.
Provisions for the use of admixtures for masonry mortar are not part of this European Standard but are covered by EN 998-1 and EN 998-2.

Diese Europäische Norm definiert und legt Anforderungen und Konformitätskriterien für Zusatzmittel für zementgebundenen Mauermörtel fest.
Sie gilt für zwei Arten von Zusatzmitteln, Erstarrungsverzögerer für langzeitverzögerte Mauermörtel und Luftporenbildner/Betonverflüssiger, die sowohl für Mörtel, der fertig gemischt auf die Baustelle geliefert wird, als auch für Mörtel, der auf der Baustelle hergestellt wird, verwendet werden.
Festlegungen zur praktischen Anwendung von Zusatzmitteln für Mauermörtel sind nicht Bestandteil dieser Europäischen Norm, sondern werden durch EN 998-1 und EN 998-2 erfasst.

Il s'applique à deux types d'adjuvants, les adjuvants fortement retardateurs de prise et les adjuvants entraîneurs d'air / plastifiants utilisés dans le mortier prêt à l'emploi ainsi que dans le mortier fabriqué sur chantier.
Les dispositions relatives à l’utilisation d'adjuvants de mortier à maçonner ne font pas partie de la présente norme européenne, mais de l’EN 998-1 et de l'EN 998-2.

Ta evropski standard določa ter opredeljuje zahteve in merila za skladnost za dodatke pri uporabi v zidarski malti, ki temelji na cementu. Pokriva dve vrsti dodatkov, dolgoobstojne in aerirane dodatke/plastifikatorje, ki se uporabljajo v svežih mešanicah in zidarski malti, pripravljeni na mestu samem. Določbe za uporabo dodatkov za zidarsko malto niso del tega evropskega standarda; vključene so v standarda EN 998-1 in EN 998-2.

Overview

EN 934-3:2009+A1:2012 is the CEN European Standard that defines requirements, conformity criteria, and marking and labelling rules for admixtures for masonry mortar. It applies to admixtures used in cement‑based masonry mortars - specifically two types: air‑entraining/plasticising admixtures and long‑term retarding admixtures for masonry mortar. The standard covers ready‑mixed and site‑made mortars and links to CE‑marking provisions and factory production control.

Key topics and technical requirements

• Definitions and scope - clarifies terms such as air entraining/plasticizing and long‑term set retarding admixtures and specifies performance and compliance dosage concepts.
• Performance requirements - additional, type‑specific requirements are given in tables:
  • Air‑entraining/plasticising admixtures - target total air content A1 = (17 ± 3) % by volume; air content stability after 1 h and extended mixing; water reduction ≥ 8% for standard consistence; compressive strength at 28 days ≥ 70% of control.
  • Long‑term retarding admixtures (ready to use mortar) - target air content A2 = (17 ± 3) %; consistence after 28 h within 15 mm of initial value; air content after 28 h ≥ 0.70 A2; resistance to penetration after 72 h ≥ 1.0 N/mm²; compressive strength at 28 days ≥ 70% of control.
• Test methods and sampling - references EN 480 series (notably EN 480‑13) and EN 1015 methods for consistency, air content, workable life/penetration resistance and compressive strength. Sampling and conformity control follow EN 934‑6.
• Conformity control - factory production control test frequencies and initial type testing requirements are specified to ensure ongoing compliance.
• Marking and labelling - mandatory information includes admixture designation (type, EN number, table code such as “EN 934‑3; T.3”), batch number, storage instructions and expiry, safety guidance, and manufacturer’s recommended dosage. Annex ZA addresses CE‑marking and related regulatory clauses.
• Dangerous substances - guidance on content and release of hazardous substances (informative Annex A).

Applications

• Ensures reliable performance of admixtures used in masonry mortar for open‑laying, blockwork and pointed restoration where controlled air content, workability and retardation are required.
• Used to verify products supplied to construction projects, support CE‑marking and meet project specification and regulatory compliance.

Who uses this standard

• Admixture manufacturers and formulators
• Construction product certifiers and testing laboratories
• Quality managers, specifiers and contractors working with masonry mortar
• Regulatory authorities and conformity assessment bodies
