“…Those very small liquid bridges in the dry zone will delay evaporation until the end of drying [54,59]. Some studies also demonstrated that the liquid bridges between clay particles have obvious stratification, i.e, the density of water is not homogeneous [24,57,[60][61][62]. Due to capillary action, tensile stress will be generated inside the water molecules, thereby reducing the water density and increasing the water volume [24,62].…”

Micro-computed tomography and low-field nuclear magnetic technologies were employed to investigate the evolution of the water occurrence and particle behaviors of the montmorillonite-kaolinite-quartz sand mixtures along a wetting-drying cycle. During the wetting-drying process, the total saturation was linearly related to the sample height. The cutoff values between the adsorbed water, capillary water and bulk water were roughly determined as 2.5 ms and 50 ms, respectively. In the wetting stage, the swelling under lower water content was dominated by adsorbed water, but it mainly depended on the linear increase in capillary water under higher water content. In the drying stage, the water distribution along the height was divided into apparent dry region, capillary flow region and saturated region. With continuous drying, the first region gradually expanded and the second reduced. Compared with nondeformable porous media, the range of them was smaller. If further dried to 5% water content, there will be only adsorbed water. The capillary water content was found to be linear with the sample height during drying. Consequently, the inconsistency of swelling-shrinkage deformations was mainly attributed to the hysteresis of capillary water. This work will provide basic experimental data and guidance for the subsequent simulations and theoretical model.

This work focuses on investigating the correlation between the evolution of liquid bridges and moisture migration in solid bulk cargo liquefaction. We experimentally investigate the stability of liquid bridges in static and dynamic particles. The liquid-holding capacity of static particles is determined and the formation and fracturing of liquid bridges are related to the particle distribution and particle radius. The spacing of the bottom particles determines the maximum liquid-holding capacity, while the space between the upper particles and the bottom particles determines the fracture position. The particles with larger radii have an increased liquid-holding capacity and a low volumetric moisture content, which confirms that cargo that consists entirely of large particles would be apt to have seepage and would not liquefy. Moisture migration for pendular and funicular liquid bridges during stretching and squeezing is captured. We indicate that the fusion behavior of liquid bridges is an important inducement for moisture migration, and it dramatically decreases the liquid-holding capacity. The findings suggest that cargo with low water content would still cause liquefaction and that the water content should be reduced further for the safe transport of solid bulk cargo.
