โœฆ Synopsis

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 smaller-scale, 30-200 6L, 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.

The photoacoustic signal strength was measured on a series of similar portland cement pastes dried to different water contents. Under appropriate conditions this signal is a function of only the paste's specific heat capacity and thermal conductivity. Because of this, inferences can be made about th

The objective of this study was to determine the changes in the hydration process of cement paste as increasing amounts of silica fume are incorporated at high and low w/(c+sf) ratios. The hydration process of cement/silica fume paste was followed from the estimation of heat of hydration, Ca(OH)2 co
