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....
Efficient thermal insulation is becoming increasingly important as people spend more time in buildings. Aerogel blankets are highly porous materials made of polymeric fibers coated with aerogel particles that are used for building insulation. This paper aimed to explore the effect of moisture on the thermal properties of insulating aerogel blankets, because in humid environments, condensation within building insulation heightens thermal conductivity. The thermal constants analyzer TPS measured the thermal ...
In this study, three series of high-volume fly ash (HVFA) mortars and concretes were studied using the transient plane source (TPS) technique. Each series of sample contained varying weight % of fly ash from 0 to 75%. The three sample sets were prepared by different laboratories and the results were compared. Thermal conductivity and specific heat capacity were measured, and the authors detailed their method of doing this. It was determined that the ...
Using the Transient Plane Source technique, various geopolymers, metakaolin-derived sodium (Na), sodium-potassium (NaK) and potassium (K), were tested to determine the effect of varying environmental conditions, such as temperature and humidity, on thermal conductivity. The results concluded that the thermal properties of the geopolymers derived from metakaolin are not greatly affected by the Si/Al ratio in the as-cured state. When the sodium geopolymers were tested at 50% relative humidity, the ...
