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 ...

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)

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 ...

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.

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,

The Uniaxial Creep Characteristics of Red Sandstone under Dry‐Wet Cycles [PDF]
Advances in Civil Engineering, 2020 Water is one of the most important factors that affect the long‐term stability of geotechnical engineering structures. Rainfall often results in periodic changes in the water content in underground rock, which is subjected to alternating dry‐wet cycles. In this paper, in order to study the short‐term and long‐term mechanical properties of red sandstone

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 ...
