Admixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling
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.

Overview
EN 934-2:2009/FprA1 is a CEN European standard amendment for concrete admixtures titled "Admixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling." It specifies definitions, performance requirements and conformity procedures for admixtures used in plain, reinforced and prestressed concrete produced as site-mixed, ready-mixed or precast concrete. The standard applies to admixtures for concrete of normal consistence and does not cover practical rules for concrete composition, placing or curing, nor some mixes such as semi-dry and earth-moist types.
Key topics and technical requirements
- Definitions and scope: Clear terminology for types of concrete admixtures (now including a new definition for viscosity modifying admixture - VMA).
- Performance requirements: General and type-specific requirements for admixtures used in normal-consistence concrete.
- Viscosity modifying admixtures (VMA): Amendment A1 adds VMA requirements and test criteria, including:
- Segregation (EN 12350-11 and EN 480-15): control mix SR between 15% and 30%; test mix SR ≤ 70% of control mix value.
- 28‑day compressive strength (EN 12390-3): test mix ≥ 80% of control mix strength.
- Air content (EN 12350-7): test mix air content ≤ 2% (by volume) above control mix unless otherwise declared by manufacturer.
- Conformity control and factory production control: Introduction of a normative Annex B (moved/expanded from prior Table 13) that lists required tests and their frequencies for production control (e.g., homogeneity, density, dry material, pH, chloride, alkali, segregation, compressive strength).
- Marking and labelling: Mandatory labeling and product information to ensure correct use and traceability.
- Referenced test methods: Amendment A1 adds references such as EN 480-15 (test method for VMA), EN 12350-8 and EN 12350-11 (fresh concrete tests), and others from the EN 480 and EN 12350/12390 series.
Practical applications
- Ensures consistent performance of admixtures used to control workability, setting time, air entrainment, water reduction and segregation in concrete production.
- Enables manufacturers to declare properties and conform to EU construction product requirements.
- Supports quality assurance in production of site-mixed, ready-mixed and precast concrete for building, civil engineering and infrastructure projects.
Who should use this standard
- Admixture manufacturers and formulators (product specification, labelling, factory production control).
- Ready-mix and precast concrete producers (selection and verification of admixture performance).
- Test laboratories and conformity assessment bodies (application of EN test methods and frequency tables).
- Specifiers, engineers and contractors seeking compliance with European admixture requirements.
