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 ...

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
