Crystallization of a liquid similar to that present in Portland cement at clinkering temperatures has been studied. Its composition (in wt %) is CaO = 54.8, A~203 = 22.7, Fez03 = 16.5, Si02 = 6.0. Prolonged crystallization or slow cooling yields the equilibrium phases: C3A, ferrite close to C,AF, an

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.
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 phase constitution of alite in portland cement clinker highly depends not only on the chemical composition of a raw mix but also on the kinetics of crystallization from the interstitial melt. From the melt of high supersaturation alite can be crystallized so quickly as to take up foreign ions i
