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.

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.

WETTING AND DRYING CYCLES EFFECT ON DURABILITY OF GYPSUM SOILS TREATED WITH CALCIUM CHLORIDE OR CEMENT ADDITIVES [PDF]
Tikrit Journal of Engineering Sciences, 2021 The study consists of two stages: the first one is to improve the gypsum soil with cement or calcium chloride and the second stage is to expose these soil specimens to series of wetting and drying cycles .Three soil specimens were taken and marked ...

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 ...

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.

The effect of drying-wetting cycles on the seismic properties of an anisotropic claystone [PDF]
, 2009 The evolution of bar and shear wave velocities during a drying wetting cycle on a claystone is presented. There is a clear relationship with total suction, established by means of the material water retention curve. The stiffening effect of drying decreases with sample damage.

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.

Dry–wet cycles increase pesticide residue release from soil [PDF]
Environmental Toxicology and Chemistry, 2012 AbstractSoil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9–17 years) 14C-labeled residues of the herbicides ethidimuron (ETD)

Aging of recycled aggregates mortars by drying-wetting cycles
Construction and Building Materials, 2021 ABSTRACT: Due to the large amount of CO2 emissions produced nowadays by the construction sector, the scientific community is looking for measures that will bring constructions to the be as environmental-friendly as possible. One of the most popular lines of research is the use of construction waste as recycled aggregates for the production of recycled ...

Dynamic strength of fly ash-modified loess subgrade under influences of drying-wetting cycle
Yantu gongcheng xuebao, 2020 The traffic load and the drying-wetting cycle have an important influence on the strength characteristics and stability of fly ash-modified loess subgrade. To illustrate the influences of drying-wetting cycle on the strength of the fly ash-modified loess,
