Structure and porosity of smectitic mudrocks as affected by experimental wetting—drying cycles and freezing—thawing cycles

CATENA, 1996
Abstract The erosion rates in the Vallcebre basin (Pyrenees) are controlled predominantly by the physical weathering rate of bare regolith, i.e. mudrocks. To obtain information on the influence of thermic and moisture regimes on the weathering dynamics, laboratory experiments were carried out to investigate how freezing—thawing or wetting—drying ...

Combined effects of salts and wetting–drying cycles on granite weathering

Bulletin of Engineering Geology and the Environment, 2020
Granite is one of the most applied building materials globally. Salt weathering affects the aesthetic properties of granite and reduces its durability. Accelerated granite weathering tests were conducted to study the combined effects of salts and wetting–drying cycles.

Experimental Study on the Effects of Wetting-Drying Cycles of Compacted Loess

Advanced Materials Research, 2013
It rains more concentrated in the summer with high temperature and strong evaporation in Gansu province, wetting-drying cycles usually occur in the embankment. Different collapse and uneven settlement appeared on the embankment in loess areas. Based on those engineering disease, through wetting-drying cycles tests of compacted loess, results show that ...

Effect of Wet-Dry Cycling on Swelling and Hydraulic Conductivity of GCLs

Journal of Geotechnical and Geoenvironmental Engineering, 2000
Atterberg limits, free swell, and hydraulic conductivity tests were conducted to assess how wet-dry cycling affects the plasticity and swell of bentonite, and the hydraulic conductivity of geosynth...

Water-retention curves of loess under wetting−drying cycles

Géotechnique Letters, 2019
Water-retention curves (WRCs) of intact, compacted and reconstituted loess were investigated using a pressure plate extractor. All specimens were prepared having the same initial density and subjected to two cycles of drying and wetting in the suction range of 0−400 kPa.

The effects of repeated wet-dry cycles as a component of bone weathering

Journal of Archaeological Science: Reports, 2018
Abstract Subaerial weathering is a taphonomic process that affects many archaeological and paleontological bone assemblages and is characterized by surface bleaching, loss of organic component, and progressive cracking and splintering of the bones. Although the mechanisms of such changes are not well understood, previous research has indicated that ...

Suction controlled wetting-drying cycles on a compacted scaly clay

2005
Due to their structural features and natural water content, scaly clays are being used in Sicily in the construction of core earth dams and waste isolation fills. A reliable design of the earth constructions requires the characterisation of the behaviour of the compacted scaly clay in unsaturated conditions.

Moisture transport in concrete during wetting/drying cycles

Chemistry and Materials Research, 2013
An accurate description of moisture transport in concrete is significant to determine the service life of a concrete structure. Many authors managed to describe the global moisture transport in concrete during wetting/drying cycles by using Fick’s laws of diffusion.
