Microstructure and Mechanical Properties of Expansive Clay under Drying–Wetting Cycle
Applied Sciences, 2023 Expansive clay is one of the most widely distributed soils in the world. Due to its rich content of strongly hydrophilic minerals—such as montmorillonite—expansive clay exhibits substantial swelling and shrinkage properties, and overconsolidation.

An insight into drying-wetting cycles of peat
E3S Web of Conferences, 2023 A relevant part of the geotechnical infrastructure in the north of Europe and overseas is built on soft organic soils, including peat. Peat is extremely vulnerable to climate-related hazards as increased temperature accelerates drying, shrinkage and decomposition of the organic matter.

Deterioration of the Internal Structure of Loess under Dry‐Wet Cycles [PDF]
Advances in Civil Engineering, 2020 To understand the structural damage evolution process of loess under the action of dry‐wet cycles, a triaxial test of a dry‐wet cycle was performed by considering three influencing factors: initial moisture content, amplitude of the dry‐wet cycle, and number of dry‐wet cycles.

Effects of Sodium Sulfate Attack on Concrete Incorporated with Drying‐Wetting Cycles [PDF]
Advances in Civil Engineering, 2021 It has been widely observed that sulfate attack can damage the durability of concrete. This research investigated the mass loss and damage degree of concrete under sodium sulfate attack incorporated with drying‐wetting cycles. The impact factors, including water‐binder ratio, solution concentration of sodium sulfate, fly ash content, curing time, and ...

Study on the Mechanical Properties of Red Clay under Drying‐Wetting Cycles [PDF]
Advances in Materials Science and Engineering, 2021 To study the mechanical properties of red clay under repeated dry and wet cycle test conditions, in this paper, the disturbed red clay in an engineering area in Liuzhou, Guangxi Province, was taken as the research object. By artificially controlling different dry and wet cycles in the laboratory, a direct shear test and triaxial consolidation drainage ...

Permeability and Microstructure of a Saline Intact Loess after Dry‐Wet Cycles [PDF]
Advances in Civil Engineering, 2021 Influenced by both dry‐wet cycles and salt weathering, the loess will exhibit significant changes in microstructure and permeability, which threatens the stability of loess slopes. Triaxial permeability tests and industrial computed tomography (CT) scans were carried out on saline intact loess with sodium sulfate.

Damage Features of Altered Rock Subjected to Drying‐Wetting Cycles [PDF]
Advances in Civil Engineering, 2018 An abandoned open pit was used as a tailing pond for a concentrating mill, with the height of the water surface subject to cyclic fluctuation. The effects of drying and wetting cycles on the mechanical parameters of pit rock were tested. Interactions of the hydrochemical environment, due to the dissolution of tailings, and drying and wetting cycles ...

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis [PDF]
Life, 2016 The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some manner, how were they sufficiently persistent to engage in further chemistry.
