Overview

prEN 1504-3 (CEN draft) defines requirements, identification and performance characteristics for repair concrete and mortars used to restore or replace defective concrete and to protect reinforcement. The standard covers both structural and non-structural repair methods and supports conformity assessment and factory production control (AVCP). It addresses characteristics relevant to mechanical resistance, durability and safety in case of fire.

Key Topics

• Performance characteristics relevant to mechanical resistance and stability, including:
  • shrinkage
  • permeability to gases
  • capillary absorption
  • diffusion of chloride ions
  • resistance to carbonation
  • thermal compatibility
  • adhesion
• Reaction to fire and associated test methods and classifications for safety in case of fire
• Identification characteristics and product classes to facilitate specification and traceability
• Quality control and AVCP processes: type testing, sampling and factory production control (FPC)
• Special applications and related test procedures for overlays, sprayed concrete and structural strengthening

The document references established test standards (for example EN 12190 for compressive strength, EN 13687 for thermal compatibility and EN 13501-1 for reaction to fire) to ensure consistent verification of performance.

Applications

prEN 1504-3 is intended for specifiers, manufacturers and contractors involved in concrete repair and asset preservation. Typical applications include:

• Hand-applied repair mortars for local concrete restoration
• Recasting with repair concrete to replace degraded sections
• Sprayed concrete or mortar for large-scale repair or rehabilitation
• Adding mortar or concrete for structural strengthening or to increase cover
• Applying overlays to improve physical or chemical resistance
• Replacing carbonated cover to restore reinforcement passivity

Key practical benefits:

• Improved durability and extended service life of concrete elements
• Clear criteria for mechanical performance and durability, aiding material selection
• Defined AVCP and FPC requirements to support consistent on-site quality
• Consideration of fire safety alongside mechanical and durability properties

Performance characteristics for “all intended” uses refer to the usually minimum required properties for the
addressed repair method according to this standard. This does not affect the content of the declaration of
performance by the product manufacturer with regard to the number of declared performance characteristics
or the no performance determined (NPD) option. Performance characteristics for “certain intended” uses are
effective for ensuring the performance of repair products or systems, e.g. in particular climatic conditions
(frost, moisture, sea water, de-icing salt) or special mechanical stresses.
Performance characteristics which are required for “all intended” uses are marked with ■. All other
performance characteristics which are marked with □ may be required for “certain intended” uses.
The repair system shall be selected based on an assessment of the actual or potential causes of deterioration

6.3 Special applications
For the performance characteristics for special applications of repair products or missing harmonized
European test methods see Annex B, Table B.1.
6.4 Dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content should
be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is available at
the Construction website on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/.
6.5 Reaction to fire

fl
without the necessity of a test
In the case of products which contain ≤ 1 percent by weight or volume of organic material, depending on
which fraction is the less advantageous, it is assumed that in accordance with the provisions of EC Decision
96/603/EC, including changes, they fulfil the requirements of the performance classes A1 or A1 respectively
fl
on the characteristics in respect of fire behaviour without the necessity of a test.
6.5.1.2.2 Other products
Products which do not fall within the area of application 6.5.1.2.1 shall be tested and classified in accordance
with EN 13501-1:
a) either without the necessity of further testing (CWFT) (Classified Without Further Testing), as stated in

Table 5 where it is proven that the product for repair fulfils the requirements of the class stated therein;
b) or on the basis of the testing of the product repair in accordance with the Standards stated in EN 13501-1

stated in a) is strived for.
NOTE Where the application of the products for repair is not subject to national statutory provisions, the Class F may
be declared for this characteristic. This corresponds to the NPD option (No Performance Determined).
