RELATIONSHIP BETWEEN HYGROTHERMAL PROPERTIES AND CONCRETE STRENGTH

Journal of Environmental Engineering (Transactions of AIJ), 2008
In order to evaluate the influences that differences in concrete strength have on hygrothermal behavior in walls, the water vapor permeability, equilibrium moisture content, hydraulic conductivity and thermal conductivity of concrete samples with three different strengths were measured.

Hygrothermal properties applied in numerical simulation: Interstitial condensation analysis [PDF]

Journal of Building Appraisal, 2009
The problem of moisture damage in buildings has attracted interest from the early days of the last century, but it was only with the development of hygrothermal modelling that the general topic of moisture transport in buildings became the subject of more systematic study.

Evaluation of Moisture Ageing Status of Cross‐Linked Polyethylene Insulation in Power Cables at Different Temperatures

High Voltage, EarlyView.
ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...

Hygrothermal properties of hollow brick masonry used in veneer

Journal of Physics: Conference Series, 2023
Abstract The material properties of a brick masonry are important when modelling or comparing different veneers. The effect of mortar joint, however, is somewhat an unknown variable. In this study, two different firing batches of a hollow burnt-clay brick product were tested for thermal conductivity, water vapor permeability, water ...

Combustion Performance of Silicone Rubber Polymer Insulation Material Under Damp‐Heat Ageing Conditions: Molecular Insights Into the Effects of Structural Changes on Macroscopic Properties

High Voltage, EarlyView.
ABSTRACT Silicone rubber (SR), an organic silicon polymer material, is known for its excellent heat resistance and mechanical properties. It is widely used in composite insulators and cable accessory materials. However, the ageing caused by humidity and heat significantly impacts its performance, an issue that cannot be ignored. This paper investigates

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

Plant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,
