Overview

EN 12618-1:2003 - published by CEN - is the reference European test method for assessing the adhesion and elongation capacity of injection products with limited ductility used to fill cracks and cavities in concrete structures. The standard defines specimen preparation, conditioning, injection and tensile testing procedures to determine bond strength and ductile performance of injection materials intended for concrete repair.

Key topics and technical requirements

• Scope: Tests determine adhesive bond capacity and elongation after injection into cracks of defined widths and moisture conditions.
• Specimens and test matrix:
  • Cubic concrete specimens made from reference concretes (EN 1766).
  • Two crack widths typically used: 0.3 mm and 0.5 mm.
  • Three crack moisture states: W (water‑filled), M (moist) and D (dry).
  • Three replicate specimens per condition (18 specimens total).
• Conditioning and temperatures:
  • Injection product and specimens conditioned at 21 ± 2 °C before injection.
  • Tensile/elongation testing performed at 3 ± 2 °C.
• Equipment and performance criteria:
  • Tensile test machine with axial self‑aligning loading, minimum 50 kN capacity and adjustable speed (0.01 mm/min).
  • Displacement measurement accuracy 0.001 mm (displacement transducer, gauge).
  • Pressure gauge suitable up to 6 MPa for monitoring injection pressure.
• Procedure highlights:
  • Injection via central packer; venting via side tube; stop when leakage occurs or 6 MPa reached.
  • Record load–deformation curves; note mode of failure (cohesive vs adhesive) and filling degree.
• Calculations and reporting:
  • Tensile strength = maximum load / injected cross‑sectional area (N/mm²).
  • Elongation at failure = mean of four side measurements relative to initial crack width.
  • Test report must include full specimen and test details, equipment, batch information, and results (see standard for full list).

Practical applications and users

• Who uses it:
  • Test laboratories performing type or batch testing of injection resins and grouts.
  • Manufacturers developing or certifying injection products for concrete repair.
  • Specifiers, engineers and contractors verifying product suitability for crack injection works.
  • Certification bodies and quality control teams demonstrating compliance with product standards.
• Why it matters:
  • Provides reproducible, comparable data on bond and ductility for selection of injection materials in structural repairs, leak sealing and crack rehabilitation.
  • Helps ensure long‑term performance where limited ductility and good adhesion are required.
