Cracking of silty mudstone subjected to wetting-drying cycles
Journal of Rock Mechanics and Geotechnical EngineeringCracking affected by wetting-drying cycles is a major cause of shallow failure of soft rock slopes. Knowledge of rock tensile properties and cracking behaviors helps better assess the stability of soft rock slopes. This study aims to examine the cracking

Effect of wetting-drying cycles on soil desiccation cracking behaviour [PDF]
E3S Web of Conferences, 2016 Better understanding the desiccation cracking process is essential in analysing drought effects on soil hydraulic and mechanical properties through consideration of the atmosphere-ground interaction.

Visualizing RNA polymers produced by hot wet-dry cycling [PDF]
Scientific Reports, 2022 Abstract It is possible that the transition from abiotic systems to life relied on RNA polymers that served as ribozyme-like catalysts and for storing genetic information. The source of such polymers is uncertain, but previous investigations reported that wet–dry cycles simulating prebiotic hot springs provide sufficient energy to drive ...

Strength Deterioration Mechanism of Bentonite Modified Loess After Wetting- Drying Cycles [PDF]
Scientific Reports, 2021 Abstract The employment of bentonite modified loess (BML) is a common method of constructing the anti-seepage lining of landfills in the loess region of China, and its long-term secure performance is threatened by wetting-drying (W-D) cycles.

Volume Changes and Mechanical Properties of Expansive Mudstone below Canals under Wet‐Dry/Wet‐Dry‐Freeze‐Thaw Cycles [PDF]
Advances in Civil Engineering, 2021 The complex environment in northern China is the main reason for degradation of expansive mudstone below the canals, which resulted in instability and damage of canal slopes. In this study, a serial of laboratory tests was conducted to explore the volume changes and mechanical behaviors of expansive mudstone below the canals in Xinjiang.

Sustained wet–dry cycling on early Mars
Nature, 2023 The presence of perennially wet surface environments on early Mars is well documented1,2, but little is known about short-term episodicity in the early hydroclimate3. Post-depositional processes driven by such short-term fluctuations may produce distinct structures, yet these are rarely preserved in the sedimentary record4.

Prebiotic condensation through wet–dry cycling regulated by deliquescence [PDF]
Nature Communications, 2019 AbstractWet–dry cycling is widely regarded as a means of driving condensation reactions under prebiotic conditions to generate mixtures of prospective biopolymers. A criticism of this model is its reliance on unpredictable rehydration events, like rainstorms. Here, we report the ability of deliquescent minerals to mediate the oligomerization of glycine

Durability against Wetting-Drying Cycles of Sustainable Biopolymer-Treated Soil
Polymers, 2022 The world today is more oriented towards sustainable and environmental-friendly solutions in every field of science, technology, and engineering. Therefore, novel sustainable and eco-friendly approaches for soil improvement have also emerged. One of the effective, promising, and green solutions is the utilization of biopolymers.

Wet–dry cycles impact DOM retention in subsurface soils [PDF]
Biogeosciences, 2018 Abstract. Transport and reactivity of carbon in the critical zone are highly controlled by reactions of dissolved organic matter (DOM) with subsurface soils, including adsorption, transformation and exchange. These reactions are dependent on frequent wet–dry cycles common to the unsaturated zone, particularly in semi-arid regions. To test for an effect

Chloride Ion Penetration into Cracked UHPFRC During Wetting-drying Cycles
, 2021 The subject of this paper is the extent to which, during wetting–drying cycles, chloride ions can penetrate Ultra-high-Performance Fibre Reinforced Cementitious Composites (UHPFRC) specimens subjected to combined mechanical and environmental load. Pre-cracking was obtained by subjecting prismatic specimens (40 × 40 × 60mm3) to four-point bending until ...
