Overview

EN 13894-1:2003 specifies a laboratory method to determine how dynamic loading during cure affects the strength development of structural bonding agents used in the protection and repair of concrete structures. The method uses a thick adherent shear test specimen and compares specimens cured under cyclic strain with stationary control specimens to derive a failure strength ratio.

This Part 1 procedure is intended for laboratory assessment and quality validation of adhesives and bonding agents while they cure under simulated service-like dynamic loading.

Key Topics

• Test specimen and geometry: thick adherent shear test specimen with a bonded area of 225 mm² and a target glueline thickness of (1.0 ± 0.1) mm.
• Surface preparation: degrease, grit-blast to SA 2 1/2 per EN ISO 8501-1:2001, vacuum to remove dust and mask butting surfaces with PVC tape.
• Dynamic loading parameters:
  • Strain cycled between 20 m/m and 170 m/m using a sine wave
  • Frequency (2 ± 0.1) Hz
  • Cycling begins 20 minutes after adhesive mixing and continues for 48 hours while curing
  • Curing temperature maintained at (21 ± 2) °C (ensure dynamic apparatus does not raise temperature)
• Curing and control specimens:
  • Cycled specimens: 3 pairs (6 specimens) subjected to dynamic straining, then 5 days stationary cure before testing
  • Control specimens: 3 pairs cured stationary at zero strain for 7 days
• Mechanical testing:
  • Strain control via electrical resistance strain gauge
  • Dynamic machine: minimum 10 kN capacity, capable of required cyclic strain and frequency
  • Static testing: tension to failure at 1 mm/min, load accuracy 0.1 kN
• Failure assessment:
  • Type A: cohesive failure within adhesive
  • Type B: adhesive failure at an interface
  • If mixed modes occur, record percentage area for each type (e.g., A:B = 70:30)
• Metrics:
  • Failure strength per specimen = failure load / 225 mm²
  • Failure strength ratio = mean failure strength (cycled) / mean failure strength (control)
• Report requirements: reference to method, laboratory and manufacturer details, specimen preparation and storage, individual failure loads, failure modes and the computed failure strength ratio.

Applications

• Practical tool for quality control of structural bonding agents and adhesives used in concrete repair.
• Supports material selection and acceptance testing where structures may experience dynamic loads during cure (e.g., near machinery, traffic or vibrating environments).
• Provides objective data to compare product performance and to document compliance for repair specifications.

Related Standards

• EN ISO 8501-1:2001 - referenced for steel substrate surface cleanliness and preparation (SA 2 1/2).
• Prepared by CEN/TC 104 (Sub‑Committee 8) and approved by CEN; intended for adoption as a national standard by CEN members.
