The purpose of this study was to measure the thermal conductivity of cementitious Kaolite 1600 for its potential to replace the radioactive materials in ES-2 containers. A thermal constants analyzer measured the thermal conductivity of the Kaolite samples using the transient plane source (TPS) method. Results showed that despite different densities, the thermal conductivities of the samples were similar up to 100 °C. Similar to ceramics and other insulating materials, the thermal ...
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 ...
This article describes comprehensive testing performed to increase understanding of how the thermal conductivity of ceramic fibers is affected. Non fibrous material content, temperature, and pressure were the main parameters investigated. Three different ceramic fiber samples were used in the research. Researchers discovered that the incorporation of aluminum reduced the thermal conductivity and consequently improved the insulation performance of the sample. An increase in pressure increased the thermal conductivity of ...
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. ...
Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...
