| Abstract: | The morphological changes accompanying the conversion of the hexagonal CaO·Al2O3·10H2O phase to the cubic 3CaO·Al2O3·6H2O phase were studied by scanning electron microscopy. The hydration and conversion reactions were monitored by X-ray diffraction analysis. From the micrographs, it was inferred that changes in the pore structure and the presence of large cubic crystals of questionable adhesive value were probably the principal factors responsible for the loss of strength in converted calcium aluminate cement pastes. |
