DETERMINATION OF INTENSITY OF HYDRATION HEAT DEVELOPMENT OF SILICATE BINDERS

Chemical mineralogical reactions taking place during hydration of silicate binders display by thermal manifestation qualified as hydration heat. Knowledge of time behavior of intensity of hydration heat development is important for judging properties of binder mixtures and their thermal technical behavior during hydration process. Besides, on the basis of intensity course of hydration heat development, it is possible to conclude a degree of effect on properties of binder mixtures when adding chemical additives. This paper describes possibilities of utilization of isoperibolic calorimeters for assessment of intensity of hydration heat development for cement pastes and possibilities of practical application of these measurements in building practice.
