Athabasca bitumen packed with glass beads of different permeabilities is used as a porous medium in a cylindrical geometry.
The CB react due to changes in the initial physicochemical conditions (pH and redox potential, aqueous species concentrations) and/or the introduction of "foreign" materials (iron, steel, concrete, glass, bitumen, etc).
We build our cities from stone, brick, steel, concrete, glass and bitumen – all derived from nature.
In this study, we focus on the rheology of SBS modified bitumen near and below the glass transition temperature (Tg) using the 4-mm DSR technique.
As is seen in this snapshot, a glass micromodel saturated with bitumen was secured at the centre of the inverted-bell jar using a model holder.
Fractional instantaneous heat losses from the porous media under radiation heat transfer mechanism were calculated during the actual pore-scale SAGD experiments considering the fraction of the swept area of glass micromodels, real-time bitumen-steam interface tracking, and energy dissipation calculations using information derived from the heat loss experiments.
One of these is the use of additive materials and in this study, the potential of cellulose and glass fibres to modify the rheological properties of bitumen has been investigated.
Micromodels of capillary networks etched on glass plates were developed, fabricated and then saturated with bitumen at lab conditions.
Bitumen films with a thickness of 350 400 μm were prepared on glass microscope slides and studied using atomic force microscopy (AFM) in tapping mode.
The Dirty House, built for the artists Sue Webster and Tim Noble, in Shoreditch, confronts the street with mirror-glass windows and a rough-textured layer of bitumen paint, the kind that is applied to lampposts to make them graffitiproof.
