Products and systems for the protection and repair of concrete structures - Test methods - Part 3: Determination of the adhesion of injection products, with or without thermal cycling - Slant shear method

This Part of this European Standard describes the method for determining the slant shear bond strength of all injection products intended to restore the integrity of cracked concrete and covered by prEN 1504-5.
The test may be performed upon cracks injected in the dry, damp, wet or with water flowing through them. It should always be carried out after the appropriate period of curing under the standard conditions of test detailed below, but may additionally be performed upon a further set of specimens after a period of artificial ageing by thermal cycling.
Whilst the testing of the repaired crack is normally by short term static load, it may also be performed as a creep test by long term static load, or as a dynamic test by the application of a cyclic load.

Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Teil 3: Bestimmung der Haftzugfestigkeit von Rissfüllstoffen mit oder ohne thermische Behandlung - Schrägscherfestigkeit

Dieses Dokument beschreibt ein Verfahren für die Bestimmung der Schrägscherfestigkeit von Rissfüllstoffen, die für das Wiederherstellen von gerissenem Beton vorgesehen sind und in prEN 1504 5 behandelt werden.
Die Prüfung kann auf Risse angewendet werden, bei denen die Injektion in trockene, feuchte, nasse oder wasserführende Risse erfolgt. Die Prüfung sollte immer nach der entsprechenden Aushärtedauer unter den nachfolgend beschriebenen, genormten Prüfbedingungen erfolgen, kann jedoch zusätzlich an einer weiteren Reihe von Prüfkörpern nach einer künstlichen Alterung durch thermische Behandlung durchgeführt werden.
Während die Prüfung eines instandgesetzten Risses üblicherweise mit kurzzeitiger statischer Belastung durchgeführt wird, kann sie auch als Kriechtest mit einer langzeitigen statischen Belastung oder als dynamische Prüfung durch eine zyklische Beanspruchung durchgeführt werden.

Produits et systèmes pour la protection et la réparation des structures en béton - Méthodes d'essais - Partie 3: Détermination de l'adhérence des produits d'injection, après cycles thermiques ou non - Méthode par cisaillement oblique

Le présent document décrit la méthode permettant de déterminer l'adhérence par cisaillement oblique de tous les produits d'injection destinés à rétablir l'intégrité d'un béton fissuré et couverts par le prEN 1504-5.
L'essai peut être effectué sur des fissures injectées à l'état sec, humide, mouillé ou avec écoulement d'eau. Il convient de toujours l'effectuer après la période de conservation appropriée, dans les conditions normalisées d'essai détaillées ci-après, mais il peut également être effectué sur un autre ensemble d'éprouvettes après une période de vieillissement artificiel par cycles thermiques.
Bien que l'essai sur la fissure réparée soit normalement un essai sous charge statique à court terme, il peut également être effectué sous forme d'un essai de fluage sous charge statique à long terme ou d'un essai dynamique sous l'application d'une charge cyclique.

Overview - EN 12618-3:2004 (Slant shear method)

EN 12618-3:2004 is a CEN test method for determining the slant shear bond strength of injection products used to restore cracked concrete (products covered by prEN 1504-5). The method measures the composite compressive strength of a concrete prism repaired by injection, exposing the repaired joint to a combined shear/compression stress state. Tests can be carried out with or without thermal cycling (artificial ageing) and under varying crack conditions (dry, damp, wet or with flowing water).

Key topics and technical requirements

• Test principle: compressive loading of a repaired prism with the injected joint oriented at 30° to the principal axis (slant shear method), producing a shear:compressive stress ratio of 1.73:1.
• Specimen geometry: composite and control prisms sawn to 55 × 55 × 150 mm from slabs (original slab size 55 × 150 × 150 mm).
• Preparation: controlled slab splitting using trapezoidal plates and elastomeric pads, injection of product per manufacturer’s instructions, and curing:
  • Resin systems: typically 7 days curing under standard test conditions.
  • Cementitious injection systems: typically 28 days.
• Conditioning options: dry, damp, wet, water-filled cracks; optional thermal cycling per EN 13687-4 for artificial ageing.
• Test conditions: standard laboratory environment (21 ± 2) °C, 60 ± 10% RH, specimens conditioned ≥16 h before testing.
• Number of tests: minimum of four composite and four control specimens per set of conditions.
• Loading and measurement: compression testing machine per EN 12390-4; record load at failure and mode of failure. Cross-section measured to nearest 0.5 mm.
• Result expression: compressive strength of the composite prism with failure mode observations; optional long-term creep or dynamic (cyclic) loading variants are permitted.

Practical applications and users

Who uses EN 12618-3:2004:

• Materials manufacturers (injection resins, epoxy/PU grouts) for product development and internal QA.
• Independent testing laboratories performing bond-strength verification and conformity testing.
• Consulting engineers and specifiers evaluating repair systems for structural integrity.
• Contractors validating performance for specific site conditions (wet cracks, injection against water head).
• Certification bodies and authorities assessing compliance with prEN 1504-5 requirements.

Practical benefits:

• Provides repeatable, comparable data on adhesion of injection products to cracked concrete.
• Supports selection of systems for different environmental conditions and thermal compatibility.
• Helps link repair performance to conventional concrete design parameters via composite compressive strength.
