The density related properties (specific gravity, density, apparent porosity), and thermal transport properties were determined for diorite and granite rocks taken from the Shewa-Shahbaz Garhi volcanic complex, Pakistan. All measurements were made at varying temperatures from 253-333 K to determine the effect of temperature on the properties. It was found that all of the properties investigated depended on the chemical composition of the rock samples. For a given sample, the ...
The transient plane source (TPS) technique was used to measure the thermal conductivity of three ceramic fibres with varying amounts of aluminium content. Specifically, the effect of temperature, press load per unit area and the aluminium content on thermal conductivity was studied. The three ceramic fibres studied were VK-60, ABK and Nextel/VK-80. It was experimentally determined that an increase in aluminium content resulted in decreased thermal conductivity of the ...
