Silica aerogels have extremely low thermal conductivities, potentially making them effective thermal insulators. In this study, the thermal conductivities of various samples were explored using the Transient Plane Source (TPS) Method. Samples of the silica aerogels were approximately 1.3 cm thick and between 4.1-4.3 cm in diameter, and were tested at different temperatures. Results showed that as the temperature of the samples increased from 25-50 Ā°C, thermal conductivity increased exponentially. As ...
In this paper, the physical characteristics of concretes containing three types of aggregates were examined under high temperatures. A thermal analyzer measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of well-crystallized concretes had a stronger inverse relationship with temperature than the poorly-crystallized samples did. As well, high-performance concretes retained their thermally conductive properties better than normal concretes....
