Products and systems for the protection and repair of concrete structures - Test methods - Testing of anchoring products by the pull-out method
This European Standard specifies the conditions for carrying out a pull-out test on a reinforcing steel bar (rebar) anchored in a concrete block.
The test applies to products based on hydraulic binders or synthetic resins or mixtures of these. It does not include those products intended to be used as grout around tendons used for the prestressing of concrete
Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Prüfung von Verankerungsprodukten mit der Ausziehprüfung
Diese Europäische Norm legt die Bedingungen für die Durchführung einer Ausziehprüfung an einem in einem Betonblock verankerten Bewehrungsstab fest.
Die Prüfung wird bei Produkten angewendet, die auf hydraulischen Bindemitteln oder Kunstharz beziehungsweise daraus bestehenden Gemischen beruhen. Sie gilt nicht für Produkte, die für die Verwendung als Verpressgut um Zugglieder in Spannbeton vorgesehen sind.
Produits et systemes pour la protection et la réparation des structures en béton - Méthodes d'essais - Essai d'arrachement d'une armature du béton pour les produits d'ancrage
La présente Norme européenne spécifie les conditions de réalisation d’un essai d’arrachement d’une barre d’armature en acier scellée dans un bloc de béton.
L’essai s’applique aux produits à base de liants hydrauliques, de résines synthétiques ou de mélanges des deux. Elle n’est pas applicable aux produits destinés à être utilisés en tant que coulis autour des câbles de précontrainte du béton.

EN 1881:2006 (E) 3 Foreword This document (EN 1881:2006) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by December 2008. It has been prepared by Sub-committee SC 8 "Protection and repair of concrete structures", the secretariat of which is held by AFNOR. This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It describes a method of test for determining the pull out resistance offered by a bonding grout or mortar used to anchor reinforcing bar. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 1881:2006 (E) 4 1 Scope This European Standard specifies the conditions for carrying out a pull-out test on a reinforcing steel bar (rebar) anchored in a concrete block. The test applies to products based on hydraulic binders or synthetic resins or mixtures of these. It does not include those products intended to be used as grout around tendons used for the prestressing of concrete. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The force and displacement of the rebar relative to the test-piece are measured. The test is performed on concrete, type C (0,40) in accordance with EN 1766. The test shall be carried out on dry and/or wet concrete, as described in 5.4.1 and 5.4.2, and the product may be applied vertically, horizontally or overhead, or in any combination, as requested by the manufacturer. NOTE If a bar is tested after being installed overhead it is not necessary to carry out additional tests in the other orientations. 4 Apparatus The following apparatus is required. 4.1 One mixer for concrete. 4.2 One mixer for the product to be tested. 4.3 Moulds for the preparation of concrete blocks of minimum dimensions (400 × 400 × 250) mm. 4.4 One concrete vibrator, 25 mm diameter
(EN 12390-2). 4.5 One rotary percussive drill or one diamond drill, or both, as specified by the manufacturer. 4.6 Three ribbed steel bars type B500B, diameter 16 mm, with a related rib area of 0.075 to 0.085 in
