A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.
Methods of testing cement - Part 9: Heat of hydration - Semi-adiabatic method
30-04-2004
22-10-2003
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 1An alternative procedure, called the solution method, is described in EN 196-8. Either procedure can be used independently.NOTE 2It 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 7 days for the heat of solution method (EN 196-8).
