Abstract: 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 Hot Disk TPS system was used, and the mica Hot Disk 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 situations. These reference values were much lower than the experimentally obtained numbers, and the authors suggest a review is needed to determine whether the standards in place are up to date.
