This study investigated the relationship between hygrothermal properties and bulk density of compressed earthen bricks. Thermal conductivity of compressed earthen samples was measured using a thermal apparatus with transient plane source method. Compressed earthen material with lower bulk density was found to have a lower thermal conductivity than higher bulk density materials since low bulk density samples have more pores filled with air....
Bentonite buffer is a key element in a high-level radioactive waste (HLW) repository as it dissipates decay heat from the waste to the surrounding rock. This article looked at Kyeongju bentonite as a candidate buffer material and investigated the dependence of thermal conductivity on various experimental conditions. A thermal analyzer instrument was used to measure thermal conductivity using the transient plane source method. Thermal conductivity was found to increase with ...
Hydronic Pavement (HP) is a potential alternative method of spreading sand and salt on slippery road surfaces through embedded pipes that circulate brine, oils, or glycol-water. The present study analyzes the thermal properties involved in designing a HP system. The transient plane source method was used to analyze thermal properties of asphalt with various sensor sizes. Results showed that thermal conductivity varied around 6-14% based on the different depths of ...
This paper analyzes the effects of temperature and air humidity on the thermophysical properties of laterite rocks. Thermal conductivity was measured using a thermal analyzer instrument and the sample and sensor were placed in an airtight humidity chamber. In this method, the TPS element acted as both a temperature sensor and heating element. Thermal conductivity was found to increase by 14.7% with an increase in relative humidity of ambient air....
A comparative study was conducted on the properties of lightweight cementitious composites (LWCCs) mixed with four types of filler particles; EPS beads, dry-expanded plastic microspheres, hollow glass microspheres, and fly ash cenospheres. Thermal conductivity was tested using the transient plane source method. Results showed that thermal conductivity of LWCCs are dictated by the volume of lightweight functional filler (LWF) used and are insensitive to the type of LWF....
