✦ Synopsis

The polymorphism of Ca3SiO 5 has been studied microscopically by following changes in optic properties and modes of twinning of the crystal as a function of temperature.

Besides the six modifications already established, a hitherto-unidentified monoclinic phase MS, which can be characterized only by microscopy at present, has been found to exist just below the rhombohedral phase (R). The transitions T2~-~T 3 and MI+-~M 2 that give clear thermal effects on the DTA curve show no corresponding change under the microscope.

The hydration of CasSiO= (CmS) was studied using the ESCA-technique and Krypfon-ddsorption measurements. The different hydration rates in the induction period and in the acceleration period are attributed to definite changes in the Ca/Si-ratio at the C3S surface and in the specific surface area.
