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

Finely divided fumed silica (Aerosil) has been used as a model substance to interpret the change in fractal dimension and specific surface of hardened cement paste (hcp) with relative humidity. Hcp is essentially a surface fractal at relative humidities below ca. 40% where the specific surface dimin
A freshly made Portland cement paste is a very unusual fluid. It behaves like a colloidal suspension, although cement particles are much coarser than conventional colloid size. The origins of this colloidal behaviour of a cement paste have been traced to high density and high viscosity of the paste
