Effect of Drying - Wetting Cycles on Triaxial Compression Mechanical Properties of Sandstone [PDF]
Journal of Engineering Science and Technology Review, 2016 To investigate the geological hazards caused by the action of drying-wetting cycle on rocks, we conducted a conventional triaxial compression test on sandstone under a high number of repeated drying-wetting cycles. By using the TAW-2000D microcomputer-controlled electro-hydraulic servo triaxial rock testing machine, this study investigated the ...

Impact of drying-wetting cycles on the small strain behaviour of compacted clay
Transportation Geotechnics, 2023 Small strain shear modulus (Gmax) is an important parameter for assessing the performance of compacted soils that underlie typical transport infrastructure assets such as railway tracks.

Physical Properties of Sandy Soil Affected by Soil Conditioner Under Wetting and Drying cycles
Journal of Agricultural and Marine Sciences, 1998 Information on the effectiveness of soil conditioners over a prolonged period is scarce. A laboratory experiment was undertaken to evaluate the effectiveness of a polyacrylamide (Broadleaf P4) soil conditioner on the physical properties of sandy soil ...

Investigation of Changes to Triaxial Shear Strength Parameters and Microstructure of Yili Loess with Drying-Wetting Cycles. [PDF]
Materials (Basel), 2021 This research examined the drying–wetting cycles induced changes in undrained triaxial shear strength parameters and microstructural changes of Yili loess. The drying–wetting cycles were selected as 0, 1, 3, 5, 10, 20 and 30.

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.

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 ...

Effect of Dry‐Wet Cycling on the Mechanical Properties of High‐Water Materials [PDF]
Advances in Civil Engineering, 2020 As a new grouting reinforcement material, high‐water materials (HWMs) are being increasingly applied in different fields. This means that the environment in which these HWMs are employed are varied and increasingly complex. The dehydrating and saturation cycle of HWM caused by changes in the environment is referred to as the dry‐wet cycle.
