Influence of Heat Treatment Conditions on Strength Properties of Poplar Wood (Populus deltoides) [PDF]

Iranian Journal of Wood and Paper Industries, 2012
In this research heat treatments of poplar wood in 2 different mediums (hot water and steam) at 185ºC were done in the sealed autoclave for 1 and 3 hours. Specimens were compared in density and mechanical properties.

Influence of materials' hygric properties on the hygrothermal performance of internal thermal insulation composite systems

Energy and Built Environment, 2023
Internal thermal insulation composite system (ITICS) can be an important measure for the energy-saving retrofitting of buildings. However, ITICS may cause harmful effects on the hygrothermal performance of building envelopes.

Study on the Effect of Combined Nanosilver- Hygrothermal Treatments on Wood Properties [PDF]

Iranian Journal of Wood and Paper Industries, 2014
In this research, the combined effect of impregnation of wood with nanosilver solution and hygrothermal treatment on some physical and mechanical properties of beech (Fagus orientalis Lipskey) and spruce (Piceaabies) woods was studied.

Multiscale Interfacial Engineering Enables Robust Reconstituted Wood

Advanced Science, EarlyView.
Conventional adhesives used in wood composites create heterogeneous interfaces that cause stress concentration under humid or aqueous conditions, thereby compromising long‐term stability. A synergistic strategy integrating interfacial reconstruction and water‐induced regeneration transforms heterogeneous interfaces into homogeneous ones with ...

The Significance of Using Temperature-Dependent Material Properties in Hygrothermal Performance Assessment of Exterior Wall Systems

Buildings
The reliability of hygrothermal models depends on the quality of their inputs. Conventionally, thermal and moisture properties are treated as temperature-independent, yet previous studies have shown that many of these properties are temperature-dependent.

STUDY OF MECHANICAL AND HYGROTHERMAL PROPERTIES OF AGGLOMERATED CORK

Mechanika, 2012
The mode of development of sandwich panels with cork core by the method infusion cannot prevent the resin from penetrating inside cork. This study characterizes white cork agglomerated before and after the development of sandwich panels to see the influence of the resin on the mechanical and hygrothermic characteristics of cork.

Tuning Acetal and Disulfide Network Dynamics in Dynamic Diamine‐Cured Partially Bio‐Epoxy Networks

Journal of Applied Polymer Science, EarlyView.
This study investigates the development of high‐performance, sustainable vitrimers by balancing partially bio‐based epoxy resins with dynamic hardener chemistry. The research identifies how resin architecture and specific curing agents influence thermal stability, bond‐exchange kinetics, and environmental durability.

Hygrothermal performance and damage risk of green roofs

, 2022
S.141-163Green roofs become more and more popular especially in cities where they can help to improve the microclimate by reduced peak temperatures compared to conventional roof surfaces. They also reduce the gutter loads by rain water retention and save

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.

Exploring the variability of hygrothermal material properties in historic bricks in London [PDF]

, 2023
In the UK, a large number of traditional buildings are made of solid brick walls. If appropriate retrofit measures are taken, these buildings can contribute to achieving the UK Government's pledge to reduce greenhouse gas emissions.
