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 ...
The thermal and mechanical properties of 4 different types of concrete were studied in the temperature range of 20°C to 800°C. Thermal properties studied include: thermal conductivity, specific heat and thermal expansion. Data generated from the testing of these samples using the TPS method were used in order to generate simplified expressions of thermal and mechanical properties as a function of time....
Since cracking in concrete is usually caused by thermal processes, relevant thermophysical properties such as heat capacity and thermal conductivity are important. This article details the measurement of thermal conductivity and heat capacity using the transient plane source method of two different (0.3 and 0.4) water-to-cement (w/c) ratio hydrated cement pastes. These thermophysical properties are measured during the initial application of the cement as well as over a period of 28 days. ...
