✦ Synopsis

On a series of fully hydrated OPC pastes hydrated at two temperatures (20 and 90 °C) and on tricalcium silicate pastes hydrated at 20 o the bound water, chemical shrinkage and density of hydrates were determined. Significant differences were found between the compared groups of materials with respect to these parameters. Effects brought about by variations of the initial water-solid ratio were less significant. The absolute values of bound water content and density varied depending on how the bound water was defined and determined.

In as series of cements made out of clinkers with variable C3A/C4AF ratios and containing different amounts of gypsum, the strength development and the composition of the hydrated material were studied. For a single clinker composition the obtained strength appears to be just a function of porosity.
