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 systemes pour la protection et la réparation des structures en béton - Méthodes d'essais - Partie 3: Détermination de l'adhérence des produits d'injection, apres 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 a rétablir l'intégrité d'un béton fissuré et couverts par le prEN 1504-5.
L'essai peut etre effectué sur des fissures injectées a l'état sec, humide, mouillé ou avec écoulement d'eau. Il convient de toujours l'effectuer apres la période de conservation appropriée, dans les conditions normalisées d'essai détaillées ci-apres, mais il peut également etre effectué sur un autre ensemble d'éprouvettes apres une période de vieillissement artificiel par cycles thermiques.
Bien que l'essai sur la fissure réparée soit normalement un essai sous charge statique a court terme, il peut également etre effectué sous forme d'un essai de fluage sous charge statique a long terme ou d'un essai dynamique sous l'application d'une charge cyclique.

EN 12618-3:2004 (E) 5 4 Test method 4.1 Principle The principle of this test is the compressive testing of a restored concrete prism that is scarf jointed at 30° to its main axis, the joint having been formed by the injection repair of a straight line crack in the concrete (see Figure 3). The joint is thus subjected to a combination of shear and compressive stresses. The result is presented as the compressive strength of the composite prism (with observations upon the mode of failure), since this is easily related to conventional concrete appraisal and design procedures. The test specimens are produced by sawing prisms from concrete slabs which have been split in a controlled manner and repaired by injecting the product or system under test. Control specimens of concrete used in the preparation of the slab are also prepared and tested in a similar manner to provide comparative information. 4.2 Apparatus 4.2.1 Compression testing machine conforming to EN 12390-4. 4.2.2 Moulds for casting the concrete slabs shall comply with the accuracy and tolerance requirements of EN 12390-1 and shall be of a size to produce slabs having the dimensions specified in 4.3.8. NOTE A suitable two-gang mould may be made by preparing a steel block 150 mm x 155 mm x 40 mm and machining a slot to receive it in two opposite faces of a 150 mm cube mould complying with EN 12390-1. This then forms two mould cavities each 55 mm wide. 4.2.3 Trapezoidal mild steel plates, having dimensions shown in Figure 1, subject to a tolerance of ± 0,5 mm. 4.2.4 Elastomeric pads 150 mm x 150 mm. The characteristics of the elastomeric material need to be such as to ensure a relatively straight crack when splitting a slab. 10 mm thick reinforced rubber sheet as used in conveyor belting has been found to be suitable, as has 6 mm thick unreinforced polyurethane elastomer sheet of 90 Shore A hardness. 4.2.5 Diamond saw, suitably mounted and capable of producing clean vertical cuts through the 55 mm thickness of the concrete slab. 4.3 Preparations 4.3.1 Preparation of concrete slabs The slabs shall be cast from a reference concrete of the type MC (0,40) or MC (0,45) as defined in EN 1766. After de-moulding they shall be cured for a total of 28 days in accordance with EN 12390-2 before any further conditioning or use. 4.3.2 Slab splitting Assemble the concrete slab with the trapezoidal plates and elastomeric pads as shown in Figure 1. Place this assembly between the platens of a press1) and apply load evenly and smoothly until the slab fractures. This is illustrated at Figure 2. Release the load and remove the assembly carefully from the press. Hold the two halves of the slab lightly together, to prevent loss of any debris from the crack. This may be done by lightly clamping the slab, or by fitting a stou
