Hygrothermal properties of earth bricks
Energy and Buildings, 2014Abstract The comfort of the occupants and the quality of indoor air are becoming important parameters in the selection of building materials for use inside buildings. Earth is a material that seems to meet all the requirements, essentially because of its low environmental impact and its strong hygroscopic properties, as observed in historic earth ...

Effect of Uncertainty in the Hygrothermal Properties on Hygrothermal Modeling
2020Building envelopes are subject to the transient climate conditions. Moisture transfer which is coupled with heat transfer is an important issue in the field of building science. The moisture transfer and accumulation within building envelopes can lead to poor thermal performance, metal corrosion, wood decay, structure deterioration, microbial and mold ...

Hygrothermal Properties of Epoxy Film Adhesives
The Journal of Adhesion, 1989Abstract The hygrothermal response of high performance epoxy film adhesives, in their bulk state, has been characterized over a wide range of temperatures, following exposure to a combination of humidity (95% R.H.) and heat (50°C). Experimental results have indicated that the testing temperature has a pronounced effect on both tensile modulus and ...

Hygrothermal Material Properties Database
Defect and Diffusion Forum, 2015The principles and tools for the development of a stochastic data base that can be useful for researchers and practitioners is an objective of this work. This paper explores the construction of that data base, focusing on material properties. Principles for that construction are proposed, including: selected properties, required raw data and ...

Hygrothermal Effects on Mechanical Properties of Lumber
Journal of Structural Engineering, 1992As part of a parent study of possible environmental effects on the long‐term load‐carrying performance of structural lumber, the material characteristics of a lumber sample are evaluated in several hygrothermal states. The modulus of elasticity and modulus of rupture of sorted groups of select structural Douglas‐fir 2×4 lumber are determined from ...

Elastic properties of hygrothermally conditioned glare laminate
International Journal of Engineering Science, 2007The influences of hygrothermal conditioning on mechanical properties of a fiber/metal laminate (FML) have been investigated by tensile and compression tests. The environmental action, such as high moisture concentration, high temperatures, corrosive fluids or ultraviolet radiation (UV), can affect the performance of advanced composites during service ...

Hygrothermal Properties of Steel Fiber Reinforced Concretes
Applied Mechanics and Materials, 2016This paper defines the hygrothermal material properties (thermal conductivity, density, specific heat capacity, vapor diffusion coefficient and resistance, moisture storage function, water absorption coefficient and liquid transport coefficient) of steel fiber reinforced concretes that are widely used for industrial floors, based on laboratory ...

Hygrothermal Properties of Highly Toughened Epoxy Adhesives
The Journal of Adhesion, 2010The absorption and desorption of water in two different rubber-toughened epoxy adhesives was measured gravimetrically over a relatively wide range of temperature and relative humidity (RH). The data were fitted to a new diffusion model in which Fick's law was assumed to act in two sequential stages, each with its own diffusion coefficient and saturated

Mineral fibre filled cavity wall: Hygrothermal properties
Building Services Engineering Research and Technology, 1991An experimental study of the heat and moisture transfer processes in an insulated cavity wall was carried out under controlled steady-state winter conditions applicable to the UK, in a wall laboratory at Salford University. The overall test area of each wall, between the indoor and outdoor climatic chambers was 3 m x 3 m.
