On 16 cement pastes made from cements of different clinker composition and containing different amounts and forms of calcium sulfate the composition was determined at the beginning and end of setting. It appears that in cements of "normal" composition the setting is associated mainly with the hydrat

The composition of the calcium silicate hydrate (C-S-H) present in Portland cement pastes from eight days to five years old, and in concrete samples ten years old, has been determined by electron probe mlcro-analysis. The dependence of C-S-H composition on water/cement ratios has also been studied.
