This research looked to investigate the thermal conductivity and heating performance of asphalt mixtures containing steel slag and steel wool fibers (SWF). An instrument was used with the transient plane source method, to evaluate the effect of SWF and steel slag on the thermal conductivity of asphalt. Results showed that as the content of SWF increased to 6%, the asphalt mixtures had a higher thermal conductivity. At 8% SWF content, the uneven ...
This paper used the TPS to measure the thermal conductivity of several different spray applied fire resistive materials between a temperature of 20-1000°C. Mass loss and thermal strain were also investigated. These properties are crucial components of the material, and decide how effectively it will perform in the face of a fire. Temperature was found to have a significant impact on the thermal conductivity, mass loss and thermal strain. ...
The structural integrity of steel members is jeopardized when fire insulation is partially lost. This paper examined the thermal and mechanical properties of fire insulation under elevated temperatures to further understand thermal gradients and develop preventative safety measures. A thermal analyzer measured the thermal conductivity of the insulation material using the transient plane source (TPS) method. Results show that thermal conductivity increases with temperature because the spray-applied fire resistance materials ...
This study developed a model that used a transient plane source (TPS) sensor to measure the specific heat capacity of anisotropic materials. The underside of a sample holder with a diameter of 20 mm, and a height of 5 mm was attached to a Kapton TPS sensor. During measurements, the sample holder was hung inside a steel tube at atmospheric pressure. Results showed that the model underestimated the heat capacity, which suggests ...
