Army Vehicle Primer Properties During Wet-Dry Cycling

Corrosion, 2009
The standard QUV/Prohesion accelerated testing method simulates weathering conditions by exposing coatings to alternating wet and dry conditions. The degradation of the coatings is influenced by the transport of water and ionic species across the coating to the substrate.

Dimensional variations of Roman masonry subjected to wetting-drying cycles

Conservation and Management of Archaeological Sites, 2001
AbstractMany Roman monuments made of opus caementicium are subjected to wetting and drying phenomena caused by water or/and humidity from the ground. The action of water impregnation on the hypothetical dimensional changes in this Roman concrete has not been considered in the literature and no experimental data are available.The purpose of this work ...

Modelling Wet-Dry Cycles in the Binary Polymer Model

2023
A key question concerning the origin of life is whether polymers, such as nucleic acids and proteins, can spontaneously form in prebiotic conditions. Several studies have shown that, by alternating (i) a phase in which a system is in a water-rich condition and (ii) one in which there is a relatively small amount of water, it is possible to achieve ...

Effective stress in swelling soils during wetting drying cycles

Engineering Geology, 2016
Abstract In this study, the cyclic evolution of an effective stress parameter χ is determined for different swelling soils. This parameter can be modelled using the macro-, meso- and microscales in interaction, stemming from mercury intrusion porosimetry (MIP) tests.

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.

Durability of stabilized base courses subjected to wet–dry cycles

International Journal of Pavement Engineering, 2007
A laboratory study was undertaken to evaluate the durability of cementitiously stabilized aggregate specimens subjected to wet–dry (W-D) cycles, representing a base course in a pavement structure. Specifically, cylindrical specimens of aggregates stabilized with 15% cement kiln dust (CKD), 10% class C fly ash, or 10% fluidized bed ash were prepared ...

Autogenous healing of engineered cementitious composites under wet–dry cycles

Cement and Concrete Research, 2009
Abstract Self-healing of Engineered Cementitious Composites (ECC) subjected to two different cyclic wetting and drying regimes was investigated in this paper. To quantify self-healing, resonant frequency measurements were conducted throughout wetting–drying cycles followed by uniaxial tensile testing of self-healing ECC specimens.

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.
