Microstructural evolution of expansive clay during drying–wetting cycle

Acta Geotechnica, 2020
This paper presents a comprehensive investigation on the microstructural evolutions of expansive clay during a drying–wetting cycle, including pore size distribution (PSD) via mercury intrusion porosimetry and water distribution via nuclear magnetic resonance (NMR).

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 ...

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 ...

Creep damage properties of sandstone under dry-wet cycles

Journal of Mountain Science, 2020
Rock creep properties can be used to predict the long-term stability in rock engineering. In reservoir bank slopes, sandstones which are frequently used in the bank slope undergoing long-term effects of dry-wet (DW) cycles due to periodic water inundation and drainage may gradually accumulate creep deformation, resulting in rock structure’s damage or ...

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.

Chloride migration in PPF concrete under dry-wet cycle

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
In order to study the Cl− penetration depth in polypropylene fiber concrete with different volume, indoor artificial method was used to simulate dry-wet cycle, and the concentrations of AgNO 3 solution indicator on the Cl− concentration at the color change boundary of the specimens was investigated.
