Products and systems for the protection and repair of concrete structures - Test methods - Part 2: Determination of the adhesion of injection products, with our without thermal cycling - Adhesion by tensile bond strength

This Part of this European Standard describes a test method to determine the adhesion to hydraulic concrete of injection products. The test can be applied to polymer and cementetious injection products.
The injection may be performed upon cracks in the dry, damp, wet or with water flowing through them. The tensile bond test 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.
The test can provide an opportunity for subjective assessment of injectability.

Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Teil 2: Bestimmung der Haftzugfestigkeit von Rissfüllstoffen mit oder ohne thermische Behandlung - Haftzugfestigkeit

Dieses Dokument beschreibt ein Prüfverfahren zur Bestimmung der Haftzugfestigkeit von Rissfüllstoffen in Bezug auf hydraulischen Beton. Diese Prüfung kann auf polymere oder zementgebundene Rissfüllstoffe angewendet werden.
Die Injektion kann in trockene, feuchte, nasse oder wasserführende Risse erfolgen. Die Prüfung der Haftzugfestigkeit sollte nach der erforderlichen 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.
Die Prüfung stellt eine Möglichkeit für die subjektive Bewertung der Injizierbarkeit dar.

Produits et systemes pour la protection et la réparation des structures en béton - Méthodes d'essai - Partie 2: Détermination de l'adhérence des produits d'injection, apres cycles thermiques ou non - Adhérence par résistance en traction

Le présent document décrit une méthode d'essai qui permet de déterminer l'adhérence des produits d'injection au béton hydraulique. L'essai est applicable aux produits d'injection polymeres et a base de ciment.
L'injection peut etre réalisée dans les fissures seches, humides, mouillées ou dans lesquelles l'eau circule. Il convient de toujours effectuer l'essai d'adhérence en traction apres la période de conservation dans les conditions normalisées d'essai détaillées ci-dessous ; toutefois, il peut en outre etre effectué sur un autre ensemble d'éprouvettes apres une période de vieillissement artificiel par cycles thermiques.
L'essai permet aussi une évaluation subjective de l'injectabilité.

These composite specimens are obtained by sawing or coring a composite test piece prepared by injecting the product into an artificial crack whose moisture content is controlled (dry, damp, wet or under water). The artificial crack is formed by placing two concrete slabs face to face. NOTE This artificial crack is preferred to natural crack obtained by splitting, due to a better control of the contact area between injection grout and concrete substrate, which is of importance in the measured load. The standard conditions of test shall be (21 ± 2) °C and (60 ± 10) % R.H. SIST EN 12618-2:2004
