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,

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 ...

Drying-Wetting Cycles: Effect on Deep Soil Carbon [PDF]
Soil Systems, 2018 In the Southeast United States (U.S.), the climate is predicted to be warmer and have more severe drought in the summer. Decreasing rainfall in summer months should create more severe soil drying, which will eventually affect re-wetting cycles deeper in the soil profile.

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 ...

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.
