This European Standard specifies a method for the determination of the early age linear shrinkage of structural bonding agents covered by EN 1501-1 and EN 1504-4. It describes the procedures for the measurement of linear shrinkage from initial gel of polymer, in the form of unrestrained thin strips less than 10 mm in thickness. It is intended for measurement of early age shrinkage, for example up to 24 hours.

Diese Europäische Norm beschreibt ein Verfahren zur Bestimmung der zeitlichen Verlaufs des linearen Schwindens von Klebstoffen und Mörteln nach EN 1501-1 und prEN 1504-4. Sie beschreibt die Durchführung der Messung des unbehinderten linearen Schwindens von dünnen (20 mm) Mörtelproben vom Stadium der Gelb- bildung an (bis zu mehreren Stunden). Das Verfahren dient der Messung des frühzeitigen Schwindens, z.B. bis zu 24 h. Das Verfahren gilt auch für Polymer-/Zementmörtel für die Instandsetzung mit einem Größtkorn des Zuschlags von nicht mehr als 5 mm.

Overview

SIST EN 12617-3:2002 is a European standard developed by CEN that specifies a precise test method for determining the early age linear shrinkage of structural bonding agents used in concrete repair and protection. This standard applies to bonding agents covered by EN 1504-1 and EN 1504-4 standards. It is focused on measuring linear shrinkage from the initial polymer gel stage, particularly within the critical early curing period of up to 24 hours. By providing standardized procedures and equipment specifications, SIST EN 12617-3:2002 ensures reliable and consistent evaluation of dimensional stability in bonding agents, vital for concrete structure durability and performance.

Key Topics

• Purpose: Measures early age linear shrinkage of structural bonding polymers, critical for assessing shrinkage-induced stress risks during curing.
• Scope: Applies to bonding agents less than 10 mm thick, in unrestrained thin strips.
• Test Principle: A polymer sample is placed in a steel trough with sliding ends; linear displacement transducers track contraction or expansion as polymer cures.
• Equipment Requirements:
  • Steel mould lined with PTFE to prevent adhesion.
  • Sliding end parts with prepared surfaces for polymer adherence.
  • Linear displacement transducers with ±0.01 mm accuracy.
  • Thermocouples for temperature monitoring.
  • Environmental cabinet maintaining precise temperature (21 ± 2 °C) and humidity (60 ± 10 %) conditions.
• Test Procedure:
  • Sample preparation following manufacturer’s instructions.
  • Conditioning in environmental cabinet.
  • Real-time recording of specimen contraction and temperature up to 48 hours, with frequent data intervals in first 24 hours.
• Calculations:
  • Thermal expansion of the mould is accounted for.
  • Shrinkage strain expressed as a percentage of effective hardened specimen length.
• Test Report Requirements:
  • Detailed test conditions, sample data, equipment details, and results including shrinkage over time curves and maximum shrinkage strain.

Applications

SIST EN 12617-3:2002 is essential for manufacturers, testing laboratories, and construction professionals involved in the development, quality control, and certification of structural bonding agents for concrete protection and repair. Its practical applications include:

• Quality Assurance: Ensures bonding agents meet dimensional stability requirements to prevent premature cracking and bond failure.
• Product Development: Assists manufacturers in optimizing polymer formulations for reduced shrinkage during early curing.
• Structural Safety: Helps engineers assess potential risks of shrinkage-induced stresses affecting repaired concrete elements.
• Compliance Testing: Supports conformity assessment in line with EN 1504 series standards on structural bonding and concrete repair products.
• Research: Facilitates comparative studies and innovation in polymer-based bonding agents used in infrastructure maintenance.
