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.

EN 12617-4:2002 (E)3ForewordThis document EN 12617-4:2002 has been prepared by Technical Committee CEN/TC 104 "Concrete and relatedproducts", 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of an identical text orby endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latestby December 2002.It was prepared by sub-committee 8 "Products and systems for the protection and repair of concrete structures",the secretariat of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 ofconcrete structures.This European Standard describes two methods for determining the dimensional stability of repair products andsystems subject to conditions of drying and immersion. 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. Theother parts are:prEN 12617-1, Products and systems for the protection and repair of concrete structures - Test methods – Part 1:Determination of linear shrinkage.prEN 12617-2, Products and systems for the protection and repair of concrete structures - Test methods – Part 2:Determination of volumetric shrinkage.EN 12617-3, Products and systems for the protection and repair of concrete structures - Test methods - Part 3:Determination of early age linear shrinkage for structural bonding agents.Annex A is normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.SIST EN 12617-4:2002

Two methods are proposed, namely aprocedure 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 maximumaggregate size of 10 mm.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

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
