The fractal arrangement of hydrated cement paste
Data from samll-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.U., geometry at most degrees of water saturation is found to be that of a rough surface fractal. The samller-scale, 30 - 200 A.U., geometry is found to be a mass fractal in saturated pastes. This geometry changes gradually with drying, and becomes a rough surface fractal at saturations less than about 50 %. Completely oven dried pastes are found to have a considerably altered geometry.
