Calcium silicate hydrate - Wikipedia

Webbelite phase. Heating at the temperature of 800°C leads to transformation of CSH phases to wollastonite (CS) and belite phase (C2S) in dependence on ash matter quality in the mixture. Formation of gehlenite that is known as a retarder of cement hydratation, and WebFormation of an impermeable hydrate layer (CSH) on the surface of the C 3 S particle precludes the further dissolution of C 3 S. The hydrate layer has a lower C/S ratio compared to C 3 S. As a result Ca 2+ is released into the liquid phase (which contains OH - ), and a silica rich layer forms on the surface of the C 3 S particle.
