When testing the thermal conductivity of moist specimens, an analysis of heat and mass transfer must be conducted. Thermal conductivity measurements require a temperature gradient within the sample, however when measuring moist materials, the temperature gradient causes the moisture to be transported and dispersed within the material. During testing, phase changes can also be experienced, which may lead to latent heat. For this experiment, the thermal properties of moist autoclaved ...
This article studied the thermal conductivity of samples of autoclaved aerated concrete with various densities at high temperatures in order to produce data that could be used to assess and predict the performance of buildings during a fire. The mica sensor was employed for high temperature measurements. The values obtained by the authors experimentally were then compared against the reference values provided by national and international standards for high temperature ...
