Overview

EN 12636:1999 (adopted as SIST EN 12636:2000) is a European Standard published by CEN that specifies test methods for determining the adhesion of concrete to concrete. It covers procedures to measure the bond strength of structural bonding agents used when placing fresh concrete onto a hardened concrete substrate or when joining hardened repair mortars/overlays to existing concrete. The standard is intended for products and systems for the protection and repair of concrete structures.

Key topics and technical requirements

• Scope and applicability
  • Methods address bonding between fresh or hardened concrete and a hardened concrete substrate.
  • Applies to assessment of structural bonding agents and repair systems used on concrete structures.
• Test principles
  • Standard defines how to prepare and condition specimens, apply bonding agents, and create bonded test assemblies.
  • Procedures include controlled curing and subsequent mechanical testing to quantify adhesion or bond strength.
• Measurement and evaluation
  • Results focus on adhesion (bond) strength and observation of failure modes (e.g., cohesive failure within the repair material or adhesive failure at the interface).
  • Emphasis on reproducibility, specimen preparation, and recording environmental and curing conditions that affect bond results.
• Documentation
  • Test reports should record materials, substrate condition, conditioning history, test method used, measured bond strength and observed failure type.

Applications and who uses this standard

EN 12636 is practical for:

• Manufacturers of repair mortars, adhesives and bonding agents - to verify product performance and support datasheets.
• Testing laboratories - to carry out standardized adhesion tests and generate comparable data for certification and quality control.
• Structural and repair engineers - to select suitable bonding systems and to specify required bond performance in repair contracts.
• Contractors and asset owners - to assess compatibility and long-term performance of repair interventions on bridges, tunnels, buildings and other concrete infrastructure. Use cases include evaluating overlay systems, cast-on-site repairs, bonded precast elements and quality control of on-site bonding operations.

Related standards

• EN 1504 series (products and systems for the protection and repair of concrete structures) - for performance requirements and product specifications.
• National adoptions such as SIST EN 12636:2000 indicate local implementation and recognition of EN 12636.
