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 [PDF]
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 ...

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 ...

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)

Effect of Dry‐Wet Cycles and Freeze‐Thaw Cycles on the Antierosion Ability of Fiber‐Reinforced Loess [PDF]
Advances in Materials Science and Engineering, 2021 Compared with plain soil, polypropylene (PP) fiber‐reinforced soil has markedly improved mechanical properties and can be used in slope protection projects. To investigate the reduction law of the antierosion ability parameters of PP fiber‐reinforced loess under dry‐wet (D‐W) cycles and freeze‐thaw (F‐T) cycles, we took loess from Yan’an, China, mixed ...

Concrete shrinkage and creep under drying/wetting cycles
Cement and Concrete Research, 2021 Abstract Concrete shrinkage and creep under variable hydric conditions are important factors for the safety and durability of concrete especially in nuclear reactor or nuclear waste storage background. A large (and long – more than 900 days) experimental campaign, conducted on two different concretes, has therefore been designed to study the strains ...
