Studies of porous hydrated portland cement have been carried out to assess quantitatively some aspects of microstructural deformation due to applied stress. Hydrated portland cement paste cured for six years at a water/cement ratio of 0.6 was sliced into discs 1.25 m~ thick. These were positioned in
Data from small-angle X-ray scattering experiments are used to determine the fractal types and dimensions of hydrated portland cement pastes over a range of length scales. The larger-scale, 200-1500 A, geometry at most degrees of water saturation is found to be that of a rough surface fractal. The s
