This investigation represents an attempt to combine analytical electron microscope analysis of the composition of individual particles separated from hydrated portland cements with a micromorphological examination of the same particles usinq high-resolution scanning electron microscopy.

Analysis of individual particles of substituted ettringite in cement pastes by analytical electron microscopy was combined with micromorphological study of the same particles by SEM and TEM. Aluminum and sulfur were individually deficient in many of the particles, but there was usually enough silico
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.
