Abstract

The heat generation characteristics of cements can vary not only by type but also by manufacturer and mining location. Therefore, accurate measurement and modelling of cement hydration heat are essential to minimize the risk of cracking arising from temperature differences and deformations caused by temperature changes. This paper presents a uniquely developed calorimeter equipped with a multi-channel data acquisition system which is also suitable for the standard measurement of cement hydration heat. In this article the calibration process of the digital thermometer was described, as well as the determination of heat loss and its compensation to achieve an adiabatic environment.
