AbstractPseudomorphs of the original cement grains in hardened pastes result from differences in hydration products deposited within and between the original grain boundaries. Structures of the various hydration products, as seen in the electron microscope are described. Pose size distributions for cement pastes obtained by a variety of methods are consistent. Surface area values measured by nitrogen, adsorption decrease with the water-cement ratio. The distinctions between capillary, gel, and non-evaporable water are reviewed. The gel water resembles interlayer water in clays.
