Products and systems for the protection and repair of concrete structures - Test methods - Determination of modulus of elasticity in compression
This European Standard specifies two methods for determining the modulus of elasticity in compression for repair products and systems.
Method 1 is for products and systems with high creep characteristics typically those containing polymer binders (PC).
Method 2 is for products and systems with low creep characteristics typically those containing polymer modified (PCC) and cementitious (CC) binders.

Diese Europäische Norm legt zwei Verfahren zur Bestimmung des Elastizitätsmoduls im Druckversuch von Instandsetzungsprodukten und -systemen fest.
Verfahren 1 gilt für Produkte und Systeme mit ausgeprägten Kriecheigenschaften; diese sind üblicherweise diejenigen, die polymere Bindemittel (PC) enthalten.
Verfahren 2 gilt für Produkte und Systeme mit geringen Kriecheigenschaften; diese sind üblicherweise diejenigen, die Bindemittel mit Polymerzusätzen (PCC) oder zementhaltige Bindemittel (CC) enthalten.
Produits et systemes de protection et de réparation des structures en béton - Méthodes d'essai - Détermination du module d'élasticité en compression
La présente Norme européenne spécifie deux méthodes permettant de déterminer le module d’élasticité en compression des produits et systemes de réparation.
La méthode 1 s’applique aux produits et systemes a déformation de fluage élevée, typiquement ceux contenant des liants polymeres (PC).
La méthode 2 s’applique aux produits et systemes a faible déformation de fluage, typiquement les mortiers hydrauliques (CC) et les mortiers hydrauliques modifiés par l’ajout de polymere (PCC).

EN 196-1, Methods of testing cement — Part 1: Determination of strength EN 1504-1:2005, Products and systems for the protection and repair of concrete structures — Definitions, requirements, quality control and evaluation of conformity — Part 1: Definitions EN 1504-3:2005, Products and systems for the protection and repair of concrete structures — Definitions, requirements, quality control and evaluation of conformity — Part 3: Structural and non-structural repair EN 12190, Products and systems for the protection and repair of concrete structures — Test methods — Determination of compressive strength of repair mortar EN 12390-3, Testing hardened concrete — Part 3: Compressive strength of test specimens EN 12390-4, Testing hardened concrete — Part 4: Compressive strength — Specification for testing machines 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1504-1:2005 and EN 1504-3:2005 and the following apply. 3.1 compressive stress compressive force carried at any time by the test specimen per unit of the original cross-section 3.2 compressive strain ratio of the change in the distance between two reference points along the axis of the test specimen per unit length of the original distance 3.3 secant modulus ratio of stress to a corresponding strain, measured relative to a level of pre-stress applied to firmly bed the specimen, platens and ball seating NOTE The secant modulus is also known as the static modulus of elasticity in compression as defined in ISO 6784. 3.4 creep additional time-dependent strain that occurs in a test specimen under a constant applied stress
EN 13412:2006 (E) 5 4 Principle The principle of the test is to measure the secant modulus of the specimen by applying a controlled axial compressive load to a prism with a 4:1 aspect ratio and relating a longitudinal compressive strain to the compressive stress, thus inducing it. Two methods are used: Method 1 is for products and systems with high creep characteristics, typically those containing polymer binders (PC), where a high rate of loading is necessary to counteract the effects of creep, which can significantly reduce the calculated value of the secant modulus. Method 2 is for products and systems with low creep characteristics, typically those containing polymer modified (PCC) and cementitious (CC) binders. 5 Equipment 5.1 Mortar mixer, in accordance with EN 196-1, or a forced action pan mixer. 5.2 Moulds, prisms with a dimension of 40 mm × 40 m
