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.

1) The compression test machine at 4.2.1 may be used for this purpose, but a simple hand operated press of lesser specification will suffice. A force of about 300 kN may be required to split the plaque. SIST EN 12618-3:2004

6 NOTE This will normally give a crack width of the order of 0,2 mm to 0,5 mm. If it is desired to investigate the performance of the injection product in repairing wider cracks, the two halves of the slab may be further separated; this fact then need to be stated in the test report. 4.3.3 Preparation for injection Prepare the two ends of the crack, i.e. at the 55 mm faces, for injection by the procedure recommended by the supplier of the injection product. This may involve bonding metal or plastic tubes over the crack for use as inlet and outlet ports, or leaving a short length of crack unsealed if the injection nozzle is to be applied direct to the concrete. Seal the remainder of the crack periphery by the procedure recommended by the supplier of the injection product. Before injection of the repair composition, condition the prepared split slab in the environment under which the injection of the product is to proceed : Dry cracks. If the repair is to be carried out in dry concrete, allow the split slab to dry in air at the standard conditions of test for a period of not less than 16 h. Damp cracks. If the injection product is to be evaluated for the repair of damp concrete, treat as detailed below for wet cracks. At the end of the 48 h saturation period, remove the slab from the water and allow it to drain for 30 min before proceeding to inject. Wet cracks. If the repair is to be carried out in wet conditions, force water through the crack to displace all trapped air and then totally immerse the slab in lime-saturated water for a period of not less than 48 h. When ready to proceed with the injection, remove the slab from the water, allow the excess water to run out and then fit the injection hoses without any further delay. Water-filled cracks. If injection is to be carried out in water filled cracks, the delivery hose of the injection equipment shall be fitted to the entry port whilst the slab is still under water. For convenience of injection, the slab may then be removed from the conditioning tank, without allowing the water to drain out of the crack. If it is required to prove that the resin system can be injected against a head of water, a water supply at the desired pressure may be connected to the outlet port. 4.3.4 Injection of the repair composition Condition the components of the injection system and the mixing vessel at the standard conditions of test (or other specified conditions) for at least 16 h before proceeding. Support the slab with its principal axis vertical. The lower end of the crack shall be the entry port for the resin injection. Mix the components of the injection system in accordance with the manufacturer's instructions. Introduce the mixed product into the crack via the entry port by the method stated in the
