Interior Humidity of Concrete under Dry-Wet Cycles
Journal of Materials in Civil Engineering, 2012The 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, 2012Abstract 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, 2021During 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.

Dry/wet cycling reduces spore germination and viability in six peatland bryophytes
Plant Biology, 2023Abstract Dry/wet cycling driven by water level fluctuation in wetlands may strongly influence the destiny of seeds. However, how dry/wet cycling affects spore survival and germinability in peatland bryophytes is poorly understood. Six peatland bryophytes, three hummock‐ and three hollow‐dwelling Sphagnum species, were chosen as study species.

On the mechanical damage to tailings sands subjected to dry–wet cycles
Bulletin of Engineering Geology and the Environment, 2018The safety of tailings ponds is considered to be one of the greatest environmental challenges in the field of energy and mining engineering. Impacted by factors such as rainfall infiltration, recycling water, dry beach face evaporation, tailings sands close to the saturation line in tailings ponds are subject to frequent dry–wet (DW) cycles.

Simulation of chloride ion transport in concrete under wetting–drying cycle
, 2020In the corrosive environment of chloride, the drying–wetting alternating zones are most seriously eroded by harmful media. Firstly, based on the new porosity and tortuosity model, considering the interaction between the transport of water and the ...

Degradation mechanisms of Portland cement mortar under seawater attack and drying-wetting cycles
, 2020This study investigates the degradation mechanisms of Portland cement mortar under multiple salts attack and drying-wetting cycle condition. The results indicate that the sulfate combined with chloride salts retard the chloride diffusion and mitigate the
