PROPERTIES AND STRUCTURE OF OIL SHALE PASTES I: COMPOSITION AND PHYSICAL FEATURES

The composition and physical features of oil shale ash pastes were determined and compared with the corresponding properties of portland cement paste. In the first part presented here, the composition, chemically combined water, porosity (total, capillary and gel porosity), pore-size and pore-size distribution, and specific surface area were determined by water vapor adsorption, mercury penetration and x-ray diffraction. It was established that the structural features and the factors which control and determine these features, are essentially the same in both the ash and the portland cement pastes. In the ash paste, however, total porosity remained virtually unchanged with time. This aspect, as well as the mechanical properties of the ash paste, are presented and discussed in the second part of the paper. (Author/TRRL)
