The ambient temperature has a strong influence on the kinetics and phase formation during the hydration of hydraulic binders. Therefore for the description of hydraulic reaction, the strict observance of exact temperatures is necessary.
For this reason a compact sample holder with a temperature range of -3°C - 80°C, especially suited for the demands of the hydration reaction investigations in cement chemistry, was developed.
To enable tempering direct at the sample, heating and cooling is done by a peltier element. The sample holder with about 80 mm in diameter and a height of 30 mm has only a weight of 150 g and is inserted in the XRD device like a normal sample holder.
