Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
In order to test the protective capabilities of body armor, a clay box is placed behind the armor during testing and the penetration depth into the clay is measured after firing. Procedures for the preparation of the Plastilina clay used to make these boxes require that the clay be pre-conditioned in an oven prior to testing. The objectives of this work were to determine if the cooling of the clay ...
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 ...
Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of concrete and wood samples were measured at elevated temperatures. The measured values are compared to established literature values and show good agreement....
In this study, three series of high-volume fly ash (HVFA) mortars and concretes were studied using the transient plane source (TPS) technique. Each series of sample contained varying weight % of fly ash from 0 to 75%. The three sample sets were prepared by different laboratories and the results were compared. Thermal conductivity and specific heat capacity were measured, and the authors detailed their method of doing this. It was determined that the ...
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 ...
