Thermal Conductivity Performance Characterization of Innovative Cement-based Construction Materials

Energy demands continue to rise because of increasing population and urbanization. Maintaining a comfortable indoor temperature accounts for a significant portion of energy use worldwide, and innovative new insulative and efficient materials for building structures are at the forefront of energy conservation worldwide.  

Cement and concrete play major roles in the construction industry and researchers are seeking ways of creating better materials that provide high levels of insulation without sacrificing structural strength. Thermal conductivity is critical in the development of these materials as lower thermal conductivity values correlate to better insulative systems – but in temperate climates, too low thermal conductivity can lead to thermal strain effects and premature cracking (e.g. of cement foundations and walls). Materials scientists and engineers in the field of cement-based construction materials employ a range of innovative technologies, such as thermally conductive or insulative fillers, and microencapsulated PCMs, to tailor thermal performance of a cement-based material to the application. 

With Trident, testing thermal conductivity of these materials is easy, as sample sizes do not need to be adjusted and can be tested in a matter of seconds.  Both MTPS and TPS transient sensor can be used, depending on the objectives of the testing. Join us on Thursday October 29th, 2020 to learn more about the thermal conductivity characterization of these materials – we’ll be highlighting work from the Swineburn University of Technology and CSIRO in Australia, from the Melbourne School of Engineering in Australia, from the CSIR-Central Building Research Institute in India, and Beykent University and Istanbul University in Turkey
