For many precast applications concrete undergoes a period of curing at elevated temperatures to accelerate the development of strength. In many cases the concrete may continue to hydrate after the heat treatment. Relatively little work has been published on the direct observation of the microstructu

## 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
This paper describes the structural changes of C-S-H caused by curing at different relative humidities (R. II.) and temperatures using XRD, 2gSi NMR and thermal analysis. The results show that within the relative humidity range studied (9%-100%), the polymerization of C-S-H does not change, but that
