Experimental Study of Thermal Stability of Building Materials

As of today, the energy issues remain relevant not only in civil construction but also in transport infrastructure. Nowadays, as the concern of sustainability and energy efficiency increases, it is important to evaluate a great number of resources and their behavior while exposed to diverse climate conditions. Therefore, the aim of this paper is to analyse the relation between the thermostability of the materials with its properties as density and specific heat, through experiments with various structural materials. The experiments were carried out in a thermal chamber with the temperature ranging from zero to 20 degrees C (periodic and non-periodic) without thermal insulation materials and with sensors installed all over the structure checking the temperature. Subsequently, graphics were drawn overlapped in order to compare the results obtained; showing how heterogeneous is the heat transfer in different parts of the structure within clay brick (full-bodied), lightweight concrete and reinforced concrete. Finally, the results show that clay brick is more thermally stable, in comparison with samples shown in this article.
