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.

In order to evaluate the hydration process assumed by the Le-Chatelier theory for portland cement, the morphology and chemical composition of the residue left after the evaporation of the liquid phase was studied by electron microprobe and electronmicroscopy. The association Ca-Si-AI and the isolate
