Products and systems for the protection and repair of concrete structures - Test methods - Part 4: Determination of shrinkage and expansion
This European Standard specifies a method for measuring the dimensional stability (i.e. the shrinkage and expansion movement) due to changes in the moisture content of hydraulic mortars or concretes (CC) or polymer hydraulic cement mortars or concretes (PCC) as defined in EN 1504-1. Two methods are proposed, namely a procedure for unrestrained movement and a procedure for restrained movement.
The provisions of the standard are applicable to grout, mortar or concrete products or systems with a maximum aggregate size of 10 mm.
Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken - Prüfverfahren - Teil 4: Bestimmung des Schwindens und Quellens
Diese Europäische Norm ist Teil einer Reihe von Normen über Produkte und Systeme für den Schutz und die Instandsetzung von Betontragwerken. Diese Europäische Norm beschreibt ein Verfahren zur Messung der Maßbeständigkeit (d.h. des Schindens und Quellens) aufgrund von Änderungen des Feuchtegehalts von Produkten und Systemen für die Instandsetzung mit HC-, PCC-, und PC-Bindemitteln nach EN 1504-1.
Produits et systemes de protection et de réparation des structures en béton - Méthodes d'essai - Partie 4: Détermination du retrait et de l'expansion
La présente Norme européenne décrit une méthode de mesure de la stabilité dimensionnelle (expansion / retrait) résultant des variations de teneur en eau des mortiers hydrauliques ou bétons hydrauliques (CC), ou des mortiers ou bétons de ciment hydrauliques polymeres (PCC) tels que définis dans l'EN 1504-1. Deux méthodes sont proposées : un mode opératoire pour le mouvement libre et un mode opératoire pour le mouvement empeché.
La présente Norme européenne s'applique aux coulis, mortiers, ou aux produits ou systemes pour béton dont la taille des granulats ne dépasse pas 10 mm.

The first method measures the unrestrained shrinkage andexpansion, while the second method measures the effects of restraint on the unrestrained shrinkage andexpansion.It is one of a series of inter-related parts dealing with dimensional stability of repair products and systems.

Each compartment shall be provided a hole atthe centre of each end face to hold a measurement stud that is to be embedded in the specimen.5.2 Measurement studsStuds made of stainless steel, or other hard material that does not react with the mortar. Typical designs for Type 1recessed stud and Type 2 projecting stud are shown in Figures 1 and 2 respectively.NOTEThe design of the studs and the embedment method need to be compatible with the measuring apparatus used(see 5.3).5.3 Measuring apparatusApparatus used to measure the length of the test specimens. It shall be adjustable to give sufficient length tomeasure the minimum specimen length ± 5 mm and have an accuracy of measurement of ± 0,001 mm. It shallhave suitable fittings to receive the measurement studs (see 5.2).5.4 Calibration rodA rod made of invar metal or other material that has a similar coefficient of expansion over the range of testtemperatures. The calibration rod shall be (160 ± 1) mm in length and with ends of the same shape as themeasurement studs (see 5.2).NOTEIt is recommended that a second identical rod be available to serve as check for wear on the first rod and theseatings of the measuring apparatus (see 5.3), by comparing their apparent lengths at three-monthly intervals.SIST EN 12617-4:2002
