Hydrothermal studies showed the location of scawtite in the narrow internal tetrahedron foshagite-xonotlite-CO2-H20 of the system CaO-SiO2-C02-H20 and its compatibility with the calcium silicate hydrates in the 4-phase assemblages. The phase assemblages in this region involve scawtite, foshagite, xo

✦ Synopsis
Tobermorite formation
was studied in the system C; C3S-S-A-N-H in suspension at 180°C. Tobermorites forw~d were ~vestigated by the molybdate method and by ='AI and ~Si MAS NMR with a purpose to evaluate the influence of aluminum and sodium ions on the changes of secondary arrangements of basic silicate anion structure.

An equilibrium phase diagram has been calculated for the CaO-A1203-CaSO4-K20-H20 system at 25°C for several KOH concentrations. These KOH concentrations were chosen to relate to cement pore fluid compositions and published experimental data. In addition to the hydrates found in the CaO-A1203-CaSO4-H
The individual subsystems of the basic five component oxide system CaO-SiO2-AI203-Fe203-SO 3 are analysed for their subsolidus phase relationship. The study is confined to the portion of the system in which C2S, the key mineralogical component of belite clinker is present. As a result eighteen equil
