Methods of testing cement - Part 8: Heat of hydration - Solution method

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

Prüfverfahren für Zement - Teil 8: Hydratationswärme - Lösungsverfahren

Diese Europäische Norm beschreibt ein Verfahren zur Messung der Hydratationswärme von Zementen mit Hilfe eines Lösungskalorimeters, das so genannte Lösungsverfahren. Die Hydratationswärme wird in Joule je Gramm Zement angegeben.
Diese Europäische Norm gilt für Zemente und hydraulische Bindemittel, ungeachtet ihrer chemischen Zusam-men¬setzung.
ANMERKUNG 1   Ein anderes Verfahren, das so genannte teiladiabatische Verfahren, ist in EN 196-9 beschrieben. Beide Verfahren können unabhängig voneinander angewendet werden.
ANMERKUNG 2   Es wurde nachgewiesen, dass sich die beste Korrelation zwischen den beiden Verfahren nach sieben Tagen bei Hydratation nach dem Lösungsverfahren (EN 196-8) und nach 41 h bei Hydratation nach dem teiladia¬batischen Verfahren (EN 196-9) ergibt.

Méthodes d'essais des ciments - Partie 8: Chaleur d'hydratation - Méthode par dissolution

La présente norme européenne décrit une méthode de mesure de la chaleur d’hydratation des ciments par
calorimétrie de dissolution, appelée méthode par dissolution. La chaleur d’hydratation est exprimée en joules
par gramme de ciment.
La présente norme s’applique aux ciments et aux liants hydrauliques quelle que soit leur composition
chimique.
NOTE 1 Une autre méthode, dite méthode semi-adiabatique, est décrite dans la norme EN 196-9. Les deux
méthodes peuvent être utilisées indépendamment.
NOTE 2 Il a été démontré que la meilleure corrélation entre les deux méthodes est obtenue en comparant les valeurs
à 7 jours par la méthode par dissolution (EN 196-8) et à 41 heures par la méthode semi-adiabatique (EN 196-9).

Metode preskušanja cementa - 8. del: Toplota hidratacije - Metoda raztapljanja

Ta evropski standard opisuje metodo za določanje toplote hidratacije cementov s pomočjo kalorimetrije raztapljanja, ki je znana tudi kot metoda raztapljana. Toplota hidratacije je izražena v joulih na gram cementa. Ta standard velja za cemente in hidravlična veziva, ne glede na njihovo kemično sestavo.
