Overview

EN 12617-2:2004 is a European standard developed by CEN that specifies a test method for determining the volumetric shrinkage of crack injection products formulated with polymer thermosetting binders. This standard primarily addresses products based on epoxy and polyester binders that cure at ambient temperature or below. The accurate measurement of volumetric shrinkage is critical for assessing the performance and durability of materials used in the protection and repair of concrete structures.

Key Topics

• Scope of Standard: Focuses on thermosetting polymer binder-based crack injection products, measuring their volumetric shrinkage upon curing.
• Test Principle: Volumetric shrinkage is determined by measuring the percentage change in density between the uncured components and the cured product at controlled temperatures (21 ± 2 °C).
• Materials Covered: Products mainly include epoxy and polyester resins formulated for crack repair in concrete structures.
• Density Measurement: Initial density is calculated from the weighted densities of resin components before polymerization, while final density is measured using buoyancy in a silicone oil bath.
• Apparatus Requirements:
  • Analytical balance with accuracy to 0.001 g
  • Density measurement device
  • Silicone oil bath maintained at (21 ± 0.5) °C
  • Test tubes treated with silicone release agent
  • Thermometer, stopwatch, desiccator, and temperature-controlled environment
• Test Procedure:
  • Calculate density of resin components prior to curing based on EN ISO 2811-2.
  • Polymerize a standard specimen at ambient temperature.
  • Measure apparent mass of cured specimen in silicone oil to determine density.
  • Calculate volumetric shrinkage as a percentage difference based on densities before and after curing.
• Reporting: Test reports must include product details, preparation and curing conditions, density values, calculated shrinkage, and any deviations or special circumstances.

Applications

• Concrete Repair and Protection: This standard is essential for manufacturers and quality control laboratories testing crack injection products to ensure reliable performance in repairing concrete infrastructure.
• Material Development: Guides researchers and developers in characterizing new polymer-based injection resins and optimizing formulations for minimal shrinkage.
• Compliance and Quality Assurance: Helps construction and engineering firms verify that repair materials meet European standards for durability and structural integrity.
• Product Certification: Supports certification bodies in validating crack injection products under standardized test conditions before market approval.

Related Standards

• EN ISO 2811-2: Paints and varnishes – Determination of density – Part 2: Immersed body (plummet) method, which is referenced for measuring component densities prior to curing.
• EN 12617-1: Products and systems for the protection and repair of concrete structures – Test methods – Part 1, which may cover complementary test methodologies related to polymer-based repair materials.
• Other CEN standards related to concrete repair materials for comprehensive quality assurance in construction and restoration projects.
