Methods of testing cement - Part 9: Heat of hydration - Semi-adiabatic method

This European Standard describes a method of measuring the heat of hydration of cements by means of semi-adiabatic calorimetry, also known as the Langavant method. The aim of the test is the continuous measurement of the heat of hydration of cement during the first few days. The heat of hydration is expressed in joules per gram of cement.
This standard is applicable to all cements and hydraulic binders, whatever their chemical composition, with the exception of quick-setting cements.
NOTE 1   An alternative procedure, called the solution method, is described in EN 196-8. Either procedure can be used independently.
NOTE 2   It has been demonstrated that the best correlation between the two methods is obtained at 41 h for the semi-adiabatic method (EN 196-9) compared with seven days for the heat of solution method (EN 196-8).

Prüfverfahren für Zement - Teil 9: Hydratationswärme - Teiladiabatisches Verfahren

Diese Europäische Norm beschreibt ein Verfahren zur Messung der Hydratationswärme von Zementen mit Hilfe der teiladiabatischen Kalorimetrie, das so genannte Langavant-Verfahren. Ziel dieser Prüfung ist die kontinuierliche Messung der Hydratationswärme von Zement während der ersten Tage. Die Hydratations¬wärme wird in Joule je Gramm Zement angegeben.
Diese Europäische Norm ist anwendbar für alle hydraulischen Bindemittel, ungeachtet ihrer chemischen Zusammensetzung, mit Ausnahme von schnell erstarrenden Zementen.
ANMERKUNG 1   Ein anderes Verfahren, das so genannte Lösungsverfahren, ist in EN 196-8 beschrieben. Beide Verfahren können unabhängig voneinander angewendet werden.
ANMERKUNG 2   Es wurde nachgewiesen, dass sich die beste Korrelation zwischen den beiden Verfahren nach 41 h für das teiladiabatische Verfahren (EN 196-9) und nach 7 Tagen für das Lösungsverfahren (EN 196-8) ergibt.

Méthodes d'essais des ciments - Partie 9: Chaleur d'hydratation - Méthode semi-adiabatique

La présente norme européenne décrit une méthode de mesure de la chaleur d'hydratation
des ciments par calorimétrie semi-adiabatique, dite méthode de Langavant. L'essai a pour but
de mesurer en continu la chaleur d'hydratation du ciment au cours des tout premiers jours. La
chaleur d’hydratation est exprimée en joules par gramme de ciment.
La présente norme s'applique à tous les ciments et liants hydrauliques, quelle que soit leur
composition chimique, à l'exception des ciments à prise rapide.
NOTE 1 Une autre méthode dite méthode de dissolution est décrite dans l’EN 196-8. Les deux
méthodes peuvent être utilisées indépendamment.
NOTE 2 Il a été démontré que la meilleure corrélation entre les deux méthodes est obtenue à 41 h
par la méthode semi-adiabatique (EN 196-9), et à 7 jours par la méthode de dissolution (EN 196-8).

Metode preskušanja cementa - 9. del: Toplota hidratacije - Semiadiabatska metoda

Ta evropski standard opisuje metodo za merjenje toplote hidratacije cementov s pomočjo semiadiabatske metode, ki je znana tudi kot Langavantova metoda. Namen preskusa je neprekinjeno merjenje toplote hidratacije cementa prvih nekaj dni. Toplota hidratacije je izražena v joulih na gram cementa. Ta standard velja za vse cemente in hidravlična veziva, ne glede na njihovo kemično sestavo, z izjemo hitrovezočih cementov.
