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

Schemes are presented showing phase assemblages compatible at subsolidus temperatures. Melting commences at about 825°C in as
## 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
The CaO-A1203-CaSO4-H20 system has been investigated at 50°C and 85°C, by calculations of the equilibrium solubility surfaces of AH3, C3AH6, CH, ettringite, monosulphoaluminate and gypsum. The results indicate that monosulphoaluminate becomes a stable phase at elevated temperature. Since ettringite
