Agro-composite materials were produced from flax shaves and the properties of these composites were determined experimentally. The structure and morphology of the composites was determined by scanning electron microscopy (SEM), and their thermal conductivities were determined using the transient plane source method. These properties, as well as mechanical, hydric, and acoustic properties were determined as a function of the structure and size of the flax shaves....
The authors prepare two series of wood sand concretes by using two types of sand concretes (dune and river) and variable amounts of wood shavings in the mixture. The mechanical and thermal properties of the concretes were then studied, using the transient plane source (TPS) technique. The addition of wood shavings to the sand concrete mix improved the strength of the concretes, and didn't have much of an effect on ...
Through the use of wood shavings as a filler for sand concretes, the authors have been able to improve the thermal properties of the prepared concrete as well as reuse a waste product. The previously used concrete had a higher thermal conductivity and higher density, and through the addition of wood shavings to the concrete mixture, the density and thermal conductivity of the composites have been lowered. The transient plane ...
For the prediction of thermal conductivity using theoretical models of a composite or mixture of components, the thermal conductivities of the individual components must be known. In this study, the needle probe method was used to measure the thermal conductivity of a mixture of powder and fluid, and using the law of mixtures (Hashin-Shtrikman bounds) the thermal conductivity of the solid phase is estimated. A much simpler method exists though ...
The authors of this article look to use shredded waste tires as a component of a cement composite in order to reuse the discarded material as well as improve the thermal properties of the composite. The TPS method was used in order to determine thermal conductivities of the dry components of the composite, and the auto-coherent homogenisation model was used to determine the thermal conductivity of the rubber/cement/air ...
