An equation for determining the effective thermal conductivity of fire resistive materials using a slug calorimeter was developed, and effective thermal conductivities were measured during heating and cooling cycles of these materials. The obtained values were compared to those obtained through measurements using the hot wire, and transient plane source methods. It was determined that the obtained values were in good agreement with those measured using these two methods. The ...
An investigation was conducted to determine the thermal properties of different types of gypsum boards from the USA and Japan. The thermal conductivity and specific heat were determined at room temperature using the transient plane source technique. Measurements were first performed with the paper backing still on the boards, and then once the backing had been removed. Removing the paper resulted in a change in the specific heat, but the ...
