Abstract: The characterization of the thermophysical properties of construction materials holds a significant position in the field of buildings and industry. Among the current material options, white earth has witnessed renewed attention due to the ongoing energy and housing crisis. In comparison to conventional construction materials, such as cement, concrete, and steel, white earth in its natural state, can serve as a building material without considerable energy consumption. Its implementation carries notable environmental, social, and cultural benefits.
The objective of this study is to determine the thermal parameters, including thermal conductivity, volumetric heat capacity, specific heat, thermal diffusivity, and bulk density of this material at an ambient temperature of 20°C. The study further explores the effect of compaction rate (ranging from 0 to 1kg) and bulk density on the material’s properties. The results demonstrate that the thermal conductivity increased by 25%, rising from 0.76 to 0.953W/m/K, in response to compaction. The volumetric heat capacity is increased by 15%, while the thermal diffusivity exhibited an increase of only 10%.
