In the scope of nuclear waste disposal facilities active clays are beneficial in comparison to other materials due to their higher swelling and sealing abilities. A unique correlation has previously been established between the final swelling pressure and the dry density of MX-80 bentonite. Additionally, it has been demonstrated that the final swelling pressure is independent of the material's...
The ability of a saturated swelling porous medium to swell can be measured using a reverse osmotic swelling experiment [3]. This experiment demonstrates that the liquid pressure inside a swelling porous medium (termed vicinal fluid) is different from that of fluid outside the porous medium in equilibrium with it (termed bulk fluid), and this in turn affects the flow of fluid and the speed of...
This study focuses on the electrokinetic conditioning of expansive soils, emphasizing the physiochemical aspects – an area frequently overlooked in prior research. Expansive soils, known for their propensity to swell and shrink in response to moisture fluctuations, present formidable challenges in geotechnical engineering. These volumetric alterations can lead to soil heave and settlement,...
The evolving pore structure in soil, influenced by various physico-chemical activities such as erosion, climate change, mechanical loading, and chemical weathering, can lead to catastrophic events like landslides and slope failures. One significant factor contributing to pore structure changes in soil is the cyclic drying and wetting process, which profoundly impacts various soil properties....
Granular soft materials (e.g., hydrogel spheres) have gained considerable attention due to their potential applications in drug delivery and tissue regeneration. To enable widespread applications of these materials in practical settings, it is crucial to accurately characterise the mechanical property (e.g., Young’s modules). Typically, the elastic properties can be determined through...
Poroviscoelastic equations coupled with the hybrid mixture theory (HMT) based fluid transport equations were studied for conventional and microwave frying of foods. In poroviscoelastic foods, the porous structure, fluid flow paths, and mechanical behavior continuously change during frying. As frying progresses, smaller pores merge to form larger pores, cell wall thickness changes, pore sizes...
