Drying-wetting cycles consistently increase net nitrogen mineralization in 25 agricultural soils across intensity and number of drying-wetting cycles

Science of the Total Environment, 2020
An increase in extreme weather events such as heavy rainfall and extreme drought causes intensive and frequent drying-wetting (DW) cycles, which have strong effects on the availability of nitrogen (N) for plant growth and development. How the effects of DW cycles on N turnover vary with the intensity and number of DW cycles and soil properties has not ...

Influence of wetting–drying cycles on the compression behavior of a compacted loess from microstructure analysis

Bulletin of Engineering Geology and the Environment, 2022
This study explores the compression deformation characteristics of compacted loess after different wetting–drying (WD) cycles, by tracking microstructure changes by scanning electron microscope (SEM), laser particle size analyzer, Fourier transform ...

Evolution of mechanical behaviours of an expansive soil during drying-wetting, freeze–thaw, and drying-wetting-freeze–thaw cycles

Bulletin of Engineering Geology and the Environment, 2021
This paper investigates the volumetric, microstructural, and shear behaviours of an expansive soil during multiple drying-wetting (DW), freeze–thaw (FT), and drying-wetting-freeze–thaw (DWFT) cycles. Specimens compacted at natural moisture content and dry density were subjected to 1, 4, 6, and 10 DW, FT, or DWFT cycles. Volumetric changes were recorded

Interior Humidity of Concrete under Dry-Wet Cycles

Journal of Materials in Civil Engineering, 2012
The dry-wet cycle is one of the aggressive environmental conditions suffered by concrete. This paper focuses on the experimental study and theoretical simulation of water distribution in normal- and high-strength concrete through dry-wet cycles. The experimental results show that under dry-wet cycles, the variation in the interior humidity of concrete ...

Model of chloride penetration into cracked concrete subject to drying–wetting cycles

Construction and Building Materials, 2012
Abstract Drying and wetting cycles condition is always identified as the most unfavorable environment condition for reinforce concrete structure subjected to chloride-induced deterioration processes. When a crack occurs, it accelerates the ingress of chloride ions and affects durability.

Study on Dynamic Characteristics of Diorite Under Dry–Wet Cycle

Rock Mechanics and Rock Engineering, 2021
During the construction of tunnels in the central and western regions of China, diorite is frequently affected by vibration, blasting and water which will lead to the questions of the quality and operational safety of project. However, there are few studies on the dynamic characteristics of diorite under the action of dry–wet cycles.
