Phase change materials (PCMs) are an attractive solution for reducing energy usage because of their efficient latent heat storage abilities. This paper examined chemical and physical properties of micro-PCMs before and after their integration with concrete samples. A Thermal Constants Analyser (TPS) measured the thermal conductivity of the PCM-concrete using the transient plane source (TPS) method. Results showed that overall, the thermal conductivity of the concrete was unchanged after the ...
The authors prepare two series of wood sand concretes by using two types of sand concretes (dune and river) and variable amounts of wood shavings in the mixture. The mechanical and thermal properties of the concretes were then studied, using the transient plane source (TPS) technique. The addition of wood shavings to the sand concrete mix improved the strength of the concretes, and didn't have much of an effect on ...
Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of concrete and wood samples were measured at elevated temperatures. The measured values are compared to established literature values and show good agreement....
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 ...
The goal of this study was to obtain information on thermal properties of three types of concrete over a wide temperature range (20°C to 800°C). The three types of concrete are: high-strength concrete (HSC), self-consolidating concrete (SCC) and fly-ash concrete (FAC). The thermal data collected included thermal conductivity, specific heat and thermal expansion of the concrete samples using the TPS method. The effect of steel, propylene and other hybrid fibers ...
