Calcium-Silicate-Hydrates (C-S-H phases, C=CaO, S=SiO2, H=H2O) are the essential product of the cement hydration responsible for the performance of the resulting concrete.Hydrothermally synthesized phases in the system CaO-SiO2-H2O (CSH), the main constituents of aerated concrete and borehole cementing products, are also increasingly used as precursors for development of novel cementitious materials.Especially the compound -Ca2[HSiO4](OH)-C2SH) possesses a great potential for production of sustainable building materials like cements based on hydraulic calcium hydrosilicates (h-CHS, "Celitement").The hydrothermal synthesis of -C2SH is a rather complicated process, dominated by nucleation, extreme disequilibria and strong dependence upon starting materials and water/solid-ratio (w/s).
