Comparison of Approximate Soil Thermal Conductivity Calculations with Laboratory Measurements and New Estimation Methods for Sandy Clayey Silt

Abstract:

In this paper, the most common approximate thermal conductivity calculation methods were compared through Hungarian soil samples with laboratory measurement results and the representative values of EN ISO 13370:2007. Based on the results, the soil’s thermal conductivity can be estimated using the modified Johansen method for higher sand containing samples, and de Vries’s method for the high silt and clay containing samples. In the light of the test results, two new methods were developed, which can be used for sandy clay silt samples. These gave almost identical results compared to the measured values and were also more accurate than the other estimations in the analysed situations.
